  1. This is long so please bear with me. I’m tackling a big project in salvaging my Klipschorns from top to bottom. I wrote two people that I have come to find out produce crossover upgrades. I will start with my email to them and follow with an answer from each. What I’m looking for, is I have NO experience with either of these two shops and hope to run into those who have who can shed some light in which way to go. I sent this to ALK Engineering and Critesspeakers.com. They were both nice enough to reply the following day. Again, I know it’s long and really appreciate your help! ------------- Hello, In searching out new crossovers for my Klipschorns I ran across your website. I bought my speakers in 1977 and have moved them around the country with me. In 1987 I updated the crossovers from Klipsch and have done nothing with them since. Five years ago I moved into a new home where there was no place to place them. I was going to build a room in an outbuilding but that has yet to materialize until now. As you can see from the picture, everything is a mess. The storage garage they were in had a flood and while they were untouched by the water themselves, the humidity did a number on them. And there were rats. I love these speakers and they have served me well and when I put them in storage five years ago they, in my ears, were flawless. Now, about me. I’ve been in radio / audio all my life. I do voiceover work and I deal with sound all day, every day. At 60+ years old, I don’t know how much of my hearing is diminished. I do know that I love audio, clear, clean audio and I get a great deal of enjoyment out of reproduction as close to the source as possible. With that being said, I am going to go through these speakers meticulously, wet sanding the walnut, cleaning out the insides and replacing what needs to be replaced. Some guys are audiophiles beyond what I think they can actually hear and I don’t want to go that route, but I do want to get the most accurate and homogenous sound that I am able to appreciate with these speakers. I know this is a long email. Short answers are fine. With what I’ve described both with what you see and my personal information, what would you recommend. Thanks! Rick Riley ------- Reply from ALK: I am not sure what effect humidity has on a speaker, but it certainly isn't good! In any case, the crossover needs to be upgraded since all Klipsch crossover are poor designs to begin with! The AP12-AK3 and ES5800 is a good choice. You might pop the woofer hatch to see the condition of the woofer driver cone. Humidity might not be so good for a paper cone. I doubt any serious damage to the K55 or K77 though. -------- Reply from Critespeakers.com: Rick, The upgrade you did in 1987 actually created some future problems you would not have had without the upgrade. The upgrade to the AK-3 also made the Khorn essentially non-user serviceable with all connections soldered and with part of the crossover inside the bass bin and the rest visible on the shelf. Originally, the Khorn was made with consideration for easy service with a terminal strip on the crossover and easy to connect terminals on all the drivers. Some of the problems created in the upgrade are not really the fault of Klipsch. They did not know the monster cable they used was poor quality and often after a few years you can see the wires turning green inside the clear insulation. They also did not know that the supplier of the midrange drivers would go bankrupt and no longer supply the drivers or any spare parts like diaphragms to repair them. When that bankruptcy happened, Klipsch went back to the exact same driver you replaced and still uses it even today in the new Khorns. And the AA crossovers you replaced with the AK-3 are still considered by many the best crossovers Klipsch ever built. My recommendations to you would be that you put them back to a condition where any future maintenance is easy again with the following parts. Pair of CT120 tweeters. These new tweeters go all the way to 20khz and are a lot smoother and cleaner sounding than the K-77. The best if the K-77 tweeters can only go up to around 15khz. Pair of Type A crossovers. The type A is a very simple crossover but many consider it the best sounding crossover. It has no tweeter protection and none is needed if you go to the CT120 tweeters. You can read about them here: https://critesspeakers.com/new-tweeter-replacement-for.html Pair of A-55G midrange drivers. These have only about half the distortion of the K-55 drivers and have a smoother frequency response. You can read about this new midrange driver here: https://critesspeakers.com/k-55-replacement-the-new-a.html You could continue to use the K-33E woofers you have if they are working well. If you do want to change them, we have our CW1526C woofers. These have a nice heavy cast aluminum frame and that frame does not drain off any magnet power like the steel frame you have now does and the effect is slightly better performance at the lowest frequencies. Prices would be: Pair of CT120 tweeters $225.00 Pair of Type A crossovers $210.00 Pair of A-55G midrange drivers $350.00 Pair of midrange horn to driver gaskets $2.00 Pair of CW1526C woofers $295.00.
  2. First questions. Has anyone ever tried removing the passive radiators and sealing the back of Forte II's? Second question. Should I buy ALK Engineering Crossovers or Bob Crites Crossovers for my Forte II's?
  3. These are 1.5 years old, first used in my Lascala last year. I then ran these in my Belle for a while, and have now gone a different route for the Belle. The 5800es can be used in other applications, as im sure the ap12-500 may as well. Lots of info on these at Alk website. This being my second system did not see much use and are in the same condition i got them in. Pic of my Belle or for reference only as they...are not included;) While you may desire me to seperate these so you can use the 5800es in some other application thats not going to happen. Unless 2 people jist HAPPEN along and want both sides, i will not separate. I am no spring chicken here, and can ship safely quite easily. Cost of 4 pieces for 2 speakers is 550. Free shipping. Friends and family only.
  4. Hi Guys , I would appreciate a bit of help with the KLIPSCH KP-362 Crossover networks , something seems to be very odd - much obliged --I added a few pictures - picture 1 is the actual crossover and the speaker terminals - picture 2 is the KP 301 II SCHEMATIC which I thought would be the same -however these 2 are very different -does anyone have an insight into the klipsch pro networks for the kp 362 --and is the picture no 1 the real Mc-Coy
  5. Selling my Dx38 I bought off a forum member. Its in very good condition and has jubilee settings already installed. $300 + shipping. Location: Maine.
  6. Hi, I want to update the crossovers on my 1979 Klipschorns but am not ready to alter "my original ones".... Does anyone have AA crossovers they would be willing to sell? I would consider original ones to re-cap, recapped ones, or upgraded crossovers that work with this model Klipschorns. Let me know what you have. Thanks, Jo
  7. I have a pair of Klipschorns I purchased in 1977. In 1989 I updated the crossovers, drivers and such. Don’t know the specifics but just ordered an update ‘kit’ from Klipsch. Question: I moved, haven’t used them in two years and want to put them into a new, custom built room. I’m an audiophile in ears only and don’t get into the mechanics of using electronics like the new Xbang z1v0059 crossover with the latest Blastophere ST50009s3’s (fictitious of course). The speakers sounded great when I put them in storage two years ago and hoping they will when I hook them up again. BUT, is there an update issued since 1989 that would be worth the cost and effort for my new application?
  8. For sale is the 60th Anniversary K-Horn crossover which appeared on E-bay last year, and which was mentioned on the forum. I believe this could be AK-5 considering the date of the 60th but there is no label saying so. This is a single cross-over composed of two circuit boards, one for bass, one for mid and tweeter, as shown in the combined photos attached. As part of the sale I promise not to divulge, anywhere, information which would aid in reverse engineering such as providing a clone to anyone, photographs of components, photographs of the copper side of the pcbs, or schematics -- for a period of four years, or until similar information becomes available to the public through other sources. Price is $500. I will pay for shipping in the lower 48 via ground (UPS is easiest for me). We can make arrangements for other destinations if necessary. WMcD
  9. Well, I will soon be taking inheritance of some Cornwalls ! What year I am not exact but the pristine condition and the age of the owner I am going to guess 1990's ? I think that puts them in the II range if I read right? My question here is I have read the Caps need replacing at 20+ yrs ? does this sound reasonable and if so what about the rest. Inductors, transformers? I can ohm out a transformer but other then visual I have no way to test a Capacitor....This a good problem to have as these will be a gift! Way to excited
  10. The ordering process was painless and the package even got here a day early. I am hoping to add the new crossovers tomorrow after my 5 year-old goes to preschool -- as any parent will tell you, tinkering with stereos with a 5-year old at home is a recipe for disaster, especially if you live in an apartment. My speakers sound amazing as is -- I'm presently listening to Paul Desmond's Glad to be Unhappy as we speak and it's like a massage for your ears. I'm waiting to hear what they will sound like with refreshed crossovers and will keep everybody posted. (I also got the titanium tweeters and am planning to put them in next. I first wanted to make sure the crossover upgrade wasn't beyond my limited capabilities before tampering with fragile diaphragms. This may seem overly cautious until you've seen some of my previous misadventures in electronics).
  11. First post here...noob to the site. Bear with me....I'm old too! Testing the waters, updating my Vintage K-horns and looking to finance it...at least partially anyway, through the sale of some vintage parts. I don't really know the value and need some guidance....some price range perhaps. I bought my Khorns in the early 80's. I sent a letter (dating myself here) to Klipsch inquiring about updates to my new acquisitions and they responded with the history of my speakers (built in 1977, BBU) and told me about the upgrades available at that time. That was 1984, I have the original 1977 vintage K33 woofers in pristine condition, in Klipsch boxes, and the 1984 "upgrade" crossovers the AK-7's. they are also in excellent condition save for some dust and what seems to be the standard cankered and corroded driver leads, greenish in color within the insulation. I would appreciate any insight my fellow Klipsch fans can provide!
  12. For sale a pair of KG4 crossovers. They are out of a pair that I used to own. The capacitors have been updated. The 3uf and 8uf with Solen FastCaps and the 33uf with a bipolar electrolytic, I think it is Bendix but not certain. The mounting cups are NOT included, just what you see in the pix. $40 (PayPal) shipped in the lower 48. Thanks
  13. So I saw a listing this morning for replica Klipschorn cabinets, made to PWK specs. No drivers or crossovers. The owner recommends re-veneering since they were built 30 years ago. Would you go for it? If so, what would be your total budget for the cabs, drivers and crossovers? How much work would it take to do it right?
  14. There's a pair of Classic RF-7 speakers for sale in my area, with factory-upgraded crossovers. I'm interested but not finding much info on them. Can anyone tell me: - How do Classic RF-7's compare with RF-7II's sonically? - Are Classic RF-7's better for 2-channel music or 5.1 home theater? What types of music or movies are they best suited for? (my AVR is a Yamaha A-3000, my 2-channel amps are Odyssey Stratos Monos) - When would you choose La Scala's over Classic RF-7's or RF-7II's? Thanks in advance for enabling my latest obsession...
  15. Up for sale - a pair of AA crossovers. These are the original AAs from my ’75 Klipschorns. I dropped in a pair of ALK Universals a while ago, and originally thought I’d keep these ‘just in case’. I realize now that I don’t need to have a fallback for the Universals, so I’m letting these go. With an empty nest (second child is in college) and a few new projects on the near horizon, I am reluctantly starting to thin out my ‘extra’ toys in anticipation if the inevitable “let’s downsize” discussion with the wife. I will also be listing a few pairs of speakers in the near future. I can provide additional pics if requested. Asking $150 $125 plus shipping. SOLD Pending funds to Fjd.
  16. Greetings Kilpsch family! I just put Crites crossovers and new tweeter diaphragms in my Forte IIs. I should have paid more attention to the way the speaker wires were connected, I noted the phase of the squawker, but not the woofer. I know the tweeters are correct, because they are marked. The squawker was still connected in one of the speakers so I am pretty sure that's right. Does the phase of the woofer make any difference? My friend has an identical pair and his seem to get richer bottom end. He seems to think it does not matter, so I thought I'd put this to the experts. I'd appreciate any help on this. Thanks! Leon
  17. Hello, I am very new to this community, starting just today. I am the original owner of a pair of 1981 Belle Klipsches. A while back I had occasion to email back and forth with a tech at Klipsch about whether my speakers needed anything to keep them sounding good. He recommended buying crossover kits. Since I am not the best with a soldering iron, I sort of dismissed the idea. However, in discussing the issue with a learned colleague, I am reconsidering the change. My speakers are in mint condition and they still sound great to me. However, if a crossover kit will help make them sound even better, I am for it and I will figure out how to get the updates installed. Can anyone tell me: Are the kits worth the money and time it takes to install them? What changes can I expect to hear in the sound with the new mods? How difficult are they to install? What is included in a kit? How expensive are the kits and where do I get them> Anything else I should know about the kits? I also have a pair of mint 1978 Heresys. Should I upgrade these in any way? These are used as the main front speakers in my basement home theater while the Belles are my "high end" system speakers. Thank you! Scott in Minneapolis
  18. I've been cleaning up a pair of Klipsch Quartet's that I'll be powering with my Amps & Sound Classic Wonder single ended 6B4G triode tube amp. The squawkers and tweeters both run too high in comparison to the woofers, and I'd like to reduce them by about 5dB. Currently I have a pair of Heresy II's that I'm using $89 ALK Engineering transformer tweeter attenuators (set a -5db). What value of resisters can I use to accomplish the exact same thing without spending $89 a set? Thanks, Mike
  19. I bought new crossovers from ALK Engineering. I was wondering if anyone would be interested in the stock crossovers from a C3? They're in like-new condition. They were use three or four year before I switched them out? I can't see any reason why they couldn't be used in a C1 or C2.
  20. I have dabbled in speaker design the better part of 40 years, I've found crossover design equal parts of math, quality components and black art. I loved my CW3's right out of the box, but quickly found high powered transistor amps and horns do not make a good mix. As nice as my McIntosh MA6600 is, I discovered it (200 watts) quickly over-drove the horns, luckily I kept my Luxman MB3045 mono block tube amps (45 watts), using the Mac as a pre-amp, that made all the difference in the world. Those who know me will tell you, I never leave well enough alone. Soon I started researching crossover networks and the name ALK Engineering kept popping up. After a few emails with Al I settled on a gentle slope woofer to squawker network (AP12-600) and an extreme slope squawker to, tweeter network (ES5800). Where I'm at: the attenuation that is right for quite music is too much midrange for loud music. I think the gentle slop is over lapping in the mid range too much. So do I take the plunge and get the ES600? (at $960) If I do, is there any market for a used AP12-600? (list is $350) I am entertaining offers and advice. Thank you in advance. - TT
  21. Greetings to all, as I am a new member on your community. I am writing to share my impressions after upgrading my WD Kel84, a 15W, push pull stereo intergraded amplifier with four El84 on the power amp. http://www.world-designs.co.uk/acatalog/kel84.pdf It was bought as a kit 14 years ago from World Audio Designs in UK. First years was a truly success, matching it with a pair of Klipsch RB-35, (8 ohms / 96dB). I still can remember the warm and detailed sound I had for the first time in my life. Then after some years of great listening I got married , so the amp wasn’t fitting well on the small apartment we rent for some years…. After 5 years that my Kel84 and RB-35 were sitting (well protected) on a basement, I decided to bring them back to life. I notice that my low frequencies were not so present and tide as the old days, so as the middle frequencies were a bit muddy. I decided then to replace the electrolytic capacitors on the power supply unit, with doubling their capacity to 220uF/450v for better stability. The tubes were from the original order from WD with not so many hours on their back. Also I change my cables (speaker and interconnects) with quality ones. These changes were for better of course, but did not achieve the sound I remember. So I decided to go for the XL Upgrade that the World Audio Designs still offering. That upgrade contains almost everything, except the transformers and the chassis, with audiofile components as said. From new improved PCB to high quality capacitors and wiring. After a succesfull (technically) upgrade, I have notice that the sound for sure it has changed in many ways. First I have more 'solid body' on sound and more tighten low frequencies with a 'booming' feeling some times. I used to have a lack of low frequencies. So far so good. The problem it concerns me is the 'muddy' picture on sound with an obvious lack in details, plus a noticeable roll off in high frequencies. My aesthetic feeling is that it gives me a very very sweet and tight, but seamless (lack in details) sound. In audition, things are satisfying in easy listening, like classical or smooth jazz piano trios, but when music becomes more complicated, like classical or jazz big bands things are getting really muddy. The same occures in Rythm and blues or Rock music. Just to mention that I had to use an EQ even for the easy listening part. Also to mention that the same feeling applies to all of my inputs (cd, pc, turntable). As far I am aware, when we talk about 'roll off or cut off in high frequencies' in amplification, usually we care about capacitors, because El84 valves are capable in handling a lot higher band of frequencies than the acoustic spectrum. So I wonder if the upgrade (mainly in capacitors) was succesfull or not. Just to be sure I tested my speakers on a different amplifier (Yamaha DSP AX-620) and hey… I got the same effect…. Now I am totally confused. Is it the amp or the speakers? Is there a possibility for a burned out tweeter or a worn component in crossovers? The speakers are in excellent cosmetic condition and at a facile optical and aural test everything seems fine. Any suggestion would be very helpfull and just to notice that I am an electronic technician my self, so I will be capable for some tests or a simple repair. Any help or suggestion would be very helpful. Best regards Nikolaos Markopoulos Athens Greece

    Heresy

    If I opened up my '85 heresies and found E-2 crossovers, would that be a upgrade from a previous owner?
  23. So I had told myself that I'd wait to post anything for a few days, in regards to the new crossovers I purchased, but I felt like the events that took place in my listening room and my ears tonight might be worth sharing. So I have a pair of 88 CW II's and decided to replace the stock crossovers. Many of you here on the forum aided in my decision by offering advice, opinions and comments when I had posted on the forum about this topic. So thank you to those that participated in that thread. Ultimately the big Thanks goes out to Dean G at Aletheia Audio as I ended up choosing to go with his services. Dean replaced the caps in my stock network with Clarity Cap ESA's a sonicap and I think a couple of mundorfs. I could be wrong on that perhaps Dean will share the specifics. As I said I had planned to wait a few days before sharing my impressions. I know that there are differing opinions on the subject of break in time so I thought to be fair to both camps I'd just wait until a reasonable amount of juice had flowed through the networks before sharing impressions and opinions on them. I've decided against that as I thought some might be interested in hearing my experience as it un folds. I came home from work and waisted no time getting them reinstalled. I listened to a fairly wide array of music last night. I started with a couple of what I consider great albums from a musical, a performance and a production level. These first two albums both featured female vocals, Madeliene Peyroux, Half the Perfect World and Patricia Barbers, Cafe Blue. The cornwalls presented the music with precision and extreme clarity. There also seemed to be more low end present than I recall with the, 25 year old, stock networks which was the initial reason I suspected they were overdue for a change. Beyond that, however, I didn't find the music to be as engaging in some strange way. It felt a bit sterile or tight. The stereo image was a bit less pronounced than what I had remembered with the stock networks. The separation of instruments wasn't as defined and overall the sound stage seemed some what compressed, a bit more of a 2d image than three dimensional. I continued to run them through there paces with music ranging from Pink Floyd's Wish you were here to Steely Dan's Cant buy a thrill to various jazz recordings and ended the night with the Rachel Podger and Brecon Baroque's, 2013, Bach: double and triple concertos. I let them play all night as I went to sleep, playing classical streaming thru MOG via apple tv. Tonight, same story came home and fired up the amp and started out real mellow with Olafur Arnalds, Living Room Songs. Honestly I didn't pay much attention as I said hi to the fam and got settled in. Next I threw up Ry Cooder and Manuel Galban's Mambo Sinuendo. This album served as background music as we ate dinner. After Dinner I sat down and put Dire Straits Brother in Arms on. I've heard this album a ton of times. I see this album as a great studio album. I've heard it so many times though it doesn't really get me excited anymore out of familiarity. First track, so far away sounds good, clean and maybe a little more open than where I thought things were last night. Second track, Money for nothing, again i've heard this song so many times its hard for me to really get into it, it's one of those songs thats been played so much that it kind of becomes background music. NOT THIS TIME! Damn! where'd that come from?!? the intro literally had my heart pumping, I reached for the remote and turned it up. I wanted to hear more! After the big drum crescendo and the song really gets going I hit stop. Literally my heart was racing from the rush the music just delivered. I went and got my wife to see if she'd give me her opinion on the sound of the speakers with the new crossovers. She sat down I started to play Money for nothing. She sat there with no expression listening. Again, for me hearing the first 60 secs was like wow but I let it play for another minute until I couldn't stay silent anymore. I asked her if she thought this track sounded good. She said "I've never heard that song like that. Is that a different version? They don't play that intro on the radio." It's like the speakers are opening like a flower in bloom tonight, literally.Each track just gets a bit deeper a bit juicier. My beloved center image and sound stage is back and deeper and wider. The 3d like quality present and the music is alive and vivid in the room. I'll stop here..... I should mention that Sharon Jones and the Dap Kings, Give the People What They Want followed Dire Straits and was an amazing listen, again vivid. Everything thats come through tonight is sounding great and shimmering the music is palpable on night two with Aletheia Audio's rebuilt Cornwall II crossovers. Stay tuned
  24. Hi Klipsch Folks, Have recently acquired (from the widow of a Belle Klipsch owner) a trove of up-grade parts. They consist of brand new and un-used crossovers as well as new tweeters and mid range drive units (not the horns themselves). In addition to the two tweeters there is an extra tweeter with a broken frame (see pics). It was evidently replaced when it arrived broken. (I haven't checked but I assume it's otherwise functional.) I'm a bit fuzzy about what this equipment is worth but I assume it's upward of $1K. (The Klipsch company themselves evinced complete cluelessness when queried about the worth of these items .) Packing for shipment would be $100 and shipment would be additional. I live in Central CA and can meet anyone driving up/down Rt #5 or Rt#99… for $50.00 (We're South East of Fresno.) This would save packing and shipping expenses. Check pictures and I can answer questions via phone or email. (dbrummitt@gotsky.com) Failing response from this forum I will be listing these on ebay. Thanks for viewing this post, Dan
