Klipsch corner horns in a new room

charles tally — Sat, 21 Nov 2009 01:56:51 GMT

We have a new great room in construction (22' x 28' to be 17' at the centerline peak) that will have a "prowed" end, i.e. instead of 90 degree corners one end will have 105 degree corners. Unfortunately, this is the only end that is suitable for the horns. Will the low end response be hurt terribly with the horns in this configuration? Any suggestions to minimize the loss?

Internal speaker wiring

greg928gts — Thu, 19 Nov 2009 19:20:15 GMT

I would like to get some feedback on what you think about these cables for internal wiring for Khorns between the components and the crossover. I know I don't NEED anything more than 16ga plain wire, but I like the idea of having nice looking wires, even though I know nobody sees the wiring. I still like everything to look really nice.

These are both tinned, twisted pair. Any thoughts on tinned wire versus regular copper strand?

This one is not tinned.

I like to solder ends on like this. I think it's a very clean look. Although, I think I can do better than this with some patience.

Frequency Response Over Different Models

Rivernuggets — Fri, 20 Nov 2009 20:23:11 GMT

Hi all, I've been a Klipsch fan for about 10 years now, but have just hopped onto this Klipsch Community. Have a question that's been in my mind for a while now. Looking at the specs for some expensive models (P-37F for example ) the frequency response seems to be starved in the low end. My technical knowledge will show here, but does the 'low frequency extension' make up for that? And how so? How does LFE in the P series differ from the RF-7's response going down to 32 hz? Thanks in advance for your knowledge.

Strobe light on turntable

Coytee — Thu, 19 Nov 2009 15:22:20 GMT

Should the adjustment for the strobe allow the image to walk both forwards and backwards?

If the image is 'walking' SLOWLY to the right (counter clockwise) does that mean the platter is turning too fast or too slow?

Does the image ever really "lock" into an imovable image and not drift at all?

If it matters, I'm looking at a Thorens TD-124

KLF_20 Cabinets

rick_m — Tue, 10 Nov 2009 05:50:29 GMT

I have a set of KLF-20's and noticed the the rear baffle is loosening up. Overall the speakers are in great shape aside for a little scratch and bruise here and there. I am considering making new cabinets instead of repairing the original ones. Is there any advice or specs that could be very helpful with my project? Thank you!

Dynaco ST-70 amp and Klipsch KLF-20 - buzzing sound

Klipsher20 — Fri, 20 Nov 2009 17:56:13 GMT

Hi all,

I recently acquired the Dynaco ST-70 set, which was serviced,
power plugs replaced to new, capacitors renewed in preamp.
Amp showed suberb graph on spectrum analizer.
There are original Western Germany made tubes.
(Didn't looks at what exact model number yet).

When I connected it to old speakers Sansui x6700 it worked perfectly
(Sensitivity about 94-96).

After connecting amp with Klipsch KLF-20 with sensitivity 100,
there started constant 'zzzzzzzzzzz' sound.
Like ground sound or I felt it was like sound from tubes buzzing.
Overal sounds amazing, but hum sound is pretty big.

Wondering what it might be and how to fix it.
Do you have any ideas or advices?
Thanks,
K

Quintet II and muffled sound

obinnae — Fri, 20 Nov 2009 14:33:07 GMT

I have a set of Quintet IIs +KSW10 sub running off of an Onkyo TX-SR606 receiver. Recently set up the system and have far from clear sound quality coming form the speakers. I've changed the various settings on the receiver with no luck. The sound directly from my TV blows away the sound from the speakers right now. Any advice or thoughts on the issue???

KG4 crossovers

Forte mid range output significantly lower on one speaker

Joe1267 — Thu, 19 Nov 2009 20:05:55 GMT

Subject headings sums up my problem. I have one of my 86 Fortes where the Midrange output is noticably lower on one speaker. I have switched amp channels and the problem stays with the speaker. Other than that, it still sounds good. Treble and bass are as they should be. Am I simply looking at getting the diaphragm replacement kit to fix the issue, or is there potentially something else afoot?? Thanks in advance for any assistance...Joe

Best v. cheap option to power Klipsch KG 2.5's

colinkites2000 — Fri, 20 Nov 2009 06:16:00 GMT

Hello all, I just ordered a pair of Klipsch KG 2.5's. I have about $200 left to power them with something. I was wondering if anyone had any suggestions or what I should look for in terms of watts or spec. I'm not really an audio expert, just want to buy something to listen to. I know my budget is low. Should I just goto Best Buy and get a receiver or try to find some kind of integrated on ebay etc. ? Any input would be greatly appreciated. C

Which horn is better-cast or composite?

robroy3300 — Mon, 16 Nov 2009 19:09:47 GMT

Does anyone prefer the cast aluminium or composite plastic? I need horns for my belle clones,and do not know which I should buy.

The k-505's are what came "stock" according to Klipsch, but I have been told the k-400's sound better!

Any oppinions?

Thanks,

Rob

Port size of KSF8.5

evan judd — Fri, 20 Nov 2009 05:30:44 GMT

I recently got a pair of KSF8.5 one had port ring and the other one had an open port where the port belongs. I am guessing that this effects the accuracy and detail of the bass frequencies coming from these speakers. Does anyone know the diameter, and length of the tubes, so I may be able to fabricate something?

KG-5.2 Woofer Rattle

CallMeJoe — Fri, 20 Nov 2009 03:30:11 GMT

I recently acquired a pair of KG-5.2s and am quite pleased overall, but have one problem to resolve. One of the woofers (K-1001-K) has a rattle at extremely low frequencies that turns into a buzz as the frequency increases. Touching the woofer surround at one particular point kills the noise. I removed the woofer and examined it carefully; it appears that a small part of the surround (perhaps about 3 cm) either was never properly glued, or has somehow come loose.

Thus my question:

Do any of you know a safe way to remove the black plastic trim ring from the front of the woofer basket to gain access to reglue the surround? The trim ring appears glued to the basket, and I would hate to break the plastic attempting a repair.

I suppose that if there is no safe way to remove the trim, I could try to locate an appropriate plastic syringe and inject an adhesive between the back of the surround and the basket, but having full access to the surround while making the repair would seem preferable.

Apologies if this has been covered before, but my search turned up nothing.

Can I date my Cornwalls by serial number?

Naptown Rob — Wed, 18 Nov 2009 13:46:10 GMT

Hello all. I'm a long time Klipsch owner, but new to this community. I recently picked up a used pair of Cornwalls - a speaker I've loved since I worked at a Klipsch dealer as a teenager in 1979. Right now they're hooked up to a Denon AVR 2308CI, and sound wonderful, but soon they'll be mated with a Fisher 500C... Is there an easy way for me to figure out the age of these things? Is there a link for a serial # database? Thanks, Rob PS: Proof that I married the right woman? She told me she thought the Cornwalls would look good with the Fortes stacked on top...

BURNED La Scala

squawker — Tue, 17 Apr 2007 17:33:35 GMT

One of my relatives has a pair of 1978 La Scalas (with type AA crossovers and K77s) that were burned when transported on a trailer that caight on fire. The photo is of the one that got burned the most. The other one looks good after being sanded and horns repainted. The one that got burned the most looks a lot better in the photo now than it did before it was sanded. They still work great! I baby sat this pair for a couple of years and I noticed that the more burned one sounded brighter than the less burned one. Having been a long time Cornwall owner, I assumed that the sound of the brighter, more burned La Scala was normal (like a Cornwall) and possibly the sound of the duller, less burned La Scala was affected by the fire - I focused on the tweeters because that is where the difference could be heard. I never completely bought that theory and left it at that. I recently acquired a nice pair of 1979 La Scalas with type AA crossovers and discovered that the tweeters sounded the same as the less burned La Scala - dull, or topping out at 14KHz. After reading a thousand or so posts on the forum about crossovers, a new theory hit me. What do you think of this? -- the less burned, duller La Scala is normal and the fire turned the more burned La Scala crossover from an AA to an A (at least in part). The fire performed the mod producing a condition of brighter highs. I haven't done any swapping and probably won't.

I've searched and searched and I can only find one post with instructions to change an type AA to an A but it was unclear. Can anyone give me a better set of instructions?

Thanks,

Mark

Difference of front vs rear loaded horns?

Coytee — Wed, 11 Nov 2009 22:31:31 GMT

I get what a front loaded horn is... I'm just confused a bit on... could the rear loaded horn be considered (ever) a compression driver?

Is the logic of the rear loaded that most of the sound comes directly at you and the rear wave does what?

Or.... does most of the sound go to the rear and if so, then the front does what?

Wouldn't you get some kind of cancellations when the rear signal comes out and meets up with the front signal? (if not, what am I missing here)

I do not think I've ever heard some of these single driver, rear loaded horns. Even though they are evidently horns, might one presume that their real strength is one of articulation rather than dymanics? Or... do our Khorn type horns have more dynamics simply because they're far far larger than these smaller units? Would these smaller units have similar dynamics if they were the size of a Khorn?

Just being curious.

Yamaha P 26 direct drive, TT just stoped working, is it worth fixing?

dixierecords — Tue, 17 Nov 2009 02:30:23 GMT

I have a Yamaha P 26 direct drive, I let a friend borrow it & when I go back over a few days later, he says "it don't work". What it's doing is when you push the play button or lift the tone arm, the strobe lights up but the platter will not turn. It's not locked up, you can spin it freely by hand but that's it. Any help could be greatly used. I'm new here and look forward to hangin around.

Behringer DEQ 2496 bit the dust

greg928gts — Sat, 14 Nov 2009 01:46:28 GMT

My Behringer DEQ 2496, four years old, developed a problem a few days ago. I came into the shop and it was turning itself on and off and on and off etc... I normally keep it powered up all the time and just turn the amps off. I turned it off and about an hour later turned it back on again, and it was fine for about a minute and then started the power on off cycle again.

Power supply?

I wonder if this is a Maine saying - My EQ sh*t the bed. Anyone?

surround sound problem

RICK VALLEJOS — Mon, 16 Nov 2009 04:27:31 GMT

I just purchased a pioneer VSX56TXi reciever (used), when its on tv mode I get full 5.1 sound but when I use the blu-ray player it switches to sound just coming out of the RF7 fronts. I have read the owners manual several times but cant figure it out. The blu ray is hooked up via digital cable, any ideas???? Maybe the receiver is too old???

rf-63 rubber or foam surround soft?

shaunm — Tue, 17 Nov 2009 00:29:00 GMT

hi all, i just got my rf-63 it is a wonderful machine. But i noticed that when the rubber or foam surround around the speakers are soft? are they suppose to be like this? do you guys know what i'm talking about? like on some speakers esp. the car subwoofers the surrounds foam or rubber are hard. but on the 63's its soft but yet its so loud and sounds nice.

Is there something wrong with my Adcom GFA5500?

Rhadamanthus — Sun, 15 Nov 2009 02:24:04 GMT

It seems to run hot. I'm comparing it to my Mcintosh MC7270.

Tonight I fired up the old Adcom and let it idle, nothing else turned on, no pre-amp, CD player, nothing. After one hour, it was up to 120 deg. F.

Sound like a problem to you guys? I bought it drand new about 10 years ago. It has never been messed with. Has a soft turn off thump on on channel.

The Mcintosh barely get warm even after hours of use.

I guess I'll busting out the watt meter and see what it's pulling at idle. Then, as someone else suggested on another post, the scope.

I'll look at the output and see if anything shows.

Is it Worth It?: Refurbishing a Turntable

kfoss99 — Mon, 09 Nov 2009 02:47:37 GMT

So, I am need of a second TT. My current one is hooked up to the computer to duplicate and archive some of my LP collection.

A friend gave me an old Yamaha YP-211 that needs a new belt and, probably, an upgraded cartridge.

I was also looking around in my mother's basement and found the old Realistic Direct Drive turntable that I used as a kid. It stopped working properly over ten years ago. I like direct drive tables and am interested in bringing it back from dead.

How much is it get one of these fixed up, if needed. Also, if it will cost as much as a new TT, are these 1970s vintage tables worth it?

Thanks for your assistance,

Karl

Re-Cap Cornwall's

jwilson55 — Wed, 11 Nov 2009 15:04:59 GMT

I have replaced the caps on the B2 crossovers with the kits from B&K. Should the wiring from the crossover's to the the drivers be replaced? This wire appears to be 18 ga. It is the original wiring from Klipsch. These are 82 models speakers.

Thanks,
