  1. I'm with you on the ringing Fritz. Had that for about 3yrs now. There's a thread about it "tinnitus" going on over at the AL/JBL site. I'm tempted to try earplugs all day even at home to see if the ringing stops at night. Its not too terribly bad yet, but can certainly get annoying. Is there anything a person can do about the ringing?
  2. Standing on the flightline during all those F-4 takeoffs and flyovers is getting me back! I've continued reading about this in old threads and "Colen" stated a few years back that although you cannot hear the higher frequencies they do have harmonics that make their way down into what you can hear and make that better so to speak. Reckon thats the case? Im starting to think alot of folks spend money trying to get back something with $$$ that can't be bought. Thats hearing loss due to age and wear. I'm guilty of this myself it seems.
  3. I've been working on my speakers around here. I'm 2 channel only. Felt like my Heresy IIs not up to snuff or something. Well according to this little dilly I'm missing something alright. http://www.dak.com/reviews/3203story.cfm My wife, son and I played the audio tones there and I can hear all the low ones and up to the 12K but not the 16K. [:'(] My wife cannot hear the 12K even. My boy says he hears em all. So I guess I just about don't even need a tweeter! Maybe I should be thinking two way now. Maybe EV had it right with the T35 tweeter dying at 16K after all. I'm kinda discouraged with these finding. Brings up an interesting question though. Can anybody even hear 20K ??? 12K sounds real high IMHO. No wonder we like bass as we get older. Thats what we can hear the best.
  4. Just wondering if anybody is familiar with these speakers or Net Electronics? http://cgi.ebay.com/ALNICO-HORN-TWEETER-TWEETERS-3X7-8-OHMS-2KHZ-20KHZ_W0QQitemZ390029678715QQcmdZViewItemQQptZVintage_Electronics_R2?hash=item390029678715&_trksid=p3286.c0.m14&_trkparms=72%3A1729%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1318%7C301%3A0%7C293%3A1%7C294%3A50
  5. Dustcovers and old turntables can be found at thriftstores. Got one nearby?
  6. Thanks Daddy Dee. Im real happy with the horns. I think they will work out fine for me. The drivers are suspect of course. I have not listened to them yet. Im guessing I can mount them in the horn, hook em up straight to a low powered amp, and have a low listen without crossover for a test. The seller is not interested in taking em back. I have a bad habit of trusting people and this time it may have bitten me a little. Don't really want to file a claim and have to earn that money twice, etc, etc. Now the guy did say the horns and drivers were in studio monitors together??? I noticed US Speaker has a 3way crossover 500z & 3500hz which might just work out with an Eminence APT 200 tweeter. Just to experiment I have active crossovers that might just help me figure it all out. If I have to bail on these I might try the Selenium D250X drivers from parts-express. As one might suspect, we have limited funds and this is a project that will be pretty much cobbled together with less expensive parts. May end up being more of a Frankenspeaker than anything. That said, my 5yr. old and I are gonna have some fun no matter how it turns out. []
  7. I fired off an email to the seller. We'll see what happens. I paid with Paypal so I suspect I can get my money back.
  8. I cannot find any info on em as siren drivers either. I guess female vocals will really wail !!!. [] As for as the impedance, I figured Atlas can make that whatever for whoever. They were on Ebay. Here is the auction. Did you email this guy? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWNX:IT&item=180330175440 Seller states "they have that classic smooth sound" ....I guess thats when listened to from a war zone bunker. I'll be hookin em up and tryin em anyway. Might be music to my ears.
  9. I picked up a pair of these for my Cornscala project and wondering if these will be suitable to cross at 500hz? If not 500 I suspect 600? The horn is 12" deep and the opening is 4.5" tall. The guy I got these from said they were in studio monitors. I also got two drivers that look like Atlas PD5 VH with these horns but the drivers have a bolt through the center of the back. Any thoughts appreciated.
  10. Yet that 7ms is not corrected with passives in the Khorn. Yet folks rave over the sound. How can that be? Seems like the 7ms delay would really mess things up. [*-)]
  11. CB, its my understanding that the batting or fiberfill type stuff adds volume to the cab. In affect the woofer sees that space as larger because of the fill. Any thoughts about that or maybe its it a mute point?
  12. I tried that code back on Monday and it said "somebody elses code"
  13. I wonder if a horn driver is that much different than a soft dome speaker really.
  14. But if you gonna do like me and experiment with crossover points, speaker placement, or amp configurations, then by all means do it and have fun! Some of the best listening in my life was a kid with a noisy old tube radio with "Wolfman Jack" playing the hits.
  15. "Heresy, the Little Big Horn" A smaller speaker with a BIGger sound" Ad slogan, what do ya think? I've been listening to my Heresy IIs and really do enjoy them.
  16. Time alignment, my area of interest lately. With actives you do have the choice to pursue it or not. These speakers from the factory however are NOT aligned. You could also physically align the coils (some speakers easier said than done) vertically if you wanted to. Wow, 9ms seems like an eternity to push or pull a speaker, but what do I know? The actives I have won't even do a 9ms delay.
  17. Oh I think your right. Although I suspect the engineering is about economics as much as performance. Of course it has to be. Anyway I'm looking forward to playing with my own version of the Cornscala at the present. I really prefer the direct woofer. Im building with eminence tweeter (similar to Bobs) and woofer. Atlas driver on the mid and a midhorn thats about 1/2 way between the 400 and 700 in size. I'll admit that attempting to better the original components or speaker ideas is what I'm interested in. I have built several speakers in the past and they were good performers so I have some expectations for myself. From the sound of it you have upgraded some Klipsch engineering yourself.[]
  18. Thanks for the insight and knowledge about it guys. It'ss funny how our perception about what is and is not seems to always change when it comes to speakers. It's said we live our lives in circles and I keep circling around back to the first decent pair of speakers I ever bought. I pair of Technics SB 2680s if I remember right. I've still got em and they sure did sound good last time I listened to them, circling back around.
  19. They look like they are ready for solder to me. I have put it to many similar pins for Uncle Sam in the USAF.
  20. Looking at these speaker designs I can see where the folded horn is at a real disadvantage as far as timing goes. But a cornwalls 15" direct driver and its midhorn are probably very close timing wise. I was all about going active xovers and aligning the drivers. Now I'm not so sure its even worth doing since 99% of these speakers are not aligned and 99% of the users don't even notice or care. Its kind of a bummer really. IGNORANCE is bliss! Kinda like the relationship between K55 and K77 drivers. According to my studies the K77 is about 1/2 a good tweeter and the K55 is just a so so mid driver. I have not listened to all the offerings out there but it does seem there are upgrades available and reasonably cheap.
  21. Coytee, I know you have Jubilees and I think you made some Cornscala type speakers. Have you played with time alignment on those setups?
  22. I know when using active crossovers that electronic delay or driver placement can be considered. How do passive crossovers handle this, if at all? I think I found my answer: sfogg wrote: "Nope. The drivers are out of alignment. Like most things it is a tradeoff. The horns in that layout with the passives basically prevent you from being time aligned while on the flip side you get the distortion/dynamic benefits of the horns. Some are willing to make that tradeoff, some aren't." So if the above statement is correct for all Klipsch Heritage speakers then certainly an alignment impovement could be made. But is this even something the average person can hear? Interesting.
  23. Thats basically it. I want to experiment with horns, active xovers, 15" or bigger woofers on the bottom ported. I want to build the bass bins and then play with the whole thing to see what kind of sound I can get out of it. I like the little tube amps and they seem to be easy for me to find and certainly cheap enough. I do not want it to be real noisy though. I want it have potential for a good sounding system.
