I have a job with a fairly large conference center (100' x 100') where the consultant designed the system with ceiling speakers. It has been installed per the consultant design and the end user isn't happy with it. The problem is that the ceiling is very high (25') and the dispersion of the speakers at that height is such that it is feeding back sound right into the microphones on the stage. We are not able to get enough microphone gain into the speakers without going into feedback. I proposed a solution using surface mounted "box" style speakers that could be mounted on the ceiling in front of the stage aiming toward the back of the room. With the speakers being directional there should be very little sound coming back to the stage. I need a throw of around 80' to get to the back of the room. I intend to use the speakers for speech only. I have 2 channels at 250w 70v each available. I want to have a wide horizontal dispersion to cover the room but a narrow vertical dispersion to prevent sound coming back onto the stage. My question is this - what speakers should I use? We are new Klipsch Pro dealers and I'm not as familiar with Klipsch speakers as other brands. I'm considering the KI-102-T-SMA-II or the CA-800T. Both have a 60w tap. There is a fairly substantial price difference between the two with the KI-102 being much more expensive. What are the factors that might cause one speaker to work better vs the other. Which would be the better choise? Klipsch CA-800-T-Spec-Sheet.pdf Klipsch KI-102-SMA-II-Data-Sheet-v08.pdf

I think a small admission fee ~$5 would give a perception of more "value" and help with revenue also. I would be willing to volunteer what time I have to the cause.

If you're not keeping them, where are you and what do you want for them? I have a pair that cosmetically are a bit beat up, but they sound great.

Is the idea for the museum to be free or would admission generate revenue?

Yes - by "them" I was referring to a single cabinet with 2 drivers. Didn't mean to confuse anyone. Should have said "it" instead of them. Anyone interested?

I love the positive comments, but I still have them and I'm moving soon and don't want to have to find a storage building for these when I move. Anyone interested?

I had them set up where they were flat down to around 30hz with some help from a parametric EQ. These are meant to pump out a LOT of bass for a commercial movie theater, but with the right setup they can be some pretty powerful subs in a traditional home theater. I have 2 kids now and I haven't really sent a good signal through them in almost 5 years. I'm moving and downsizing so these need to find another home.

This is from their cinema series but I've seen it used in pro sound as well - both touring and installations. I had it in my home theater. Back when I was single I could really rock out watching movies. But now with kids I rarely have a chance to really get it breathing. I am going to be moving as well so I don't have room for it at the new house. EDIT - I already moved and I've had these sitting in storage for over a year. They need a home.

SOLD I have finally finished restoring the Heresy speakers I bought from an estate sale a few months ago. These are vintage Klipsch Heresy I speakers with consecutive serial numbers. Walnut oil finish. HWO is shown on label. Some of the pictures of the inside were taken before the caps were replaced. Serial numbers 71S211 and 71S212. Restoration included: 2 New K-22 woofers (new as in I bought them on eBay in greatcondition) new grill cloth purchased from Bob Crites to match the factory cloth 4 new 2uF capacitors (2 per speaker) Complete sanding of entire surface of both speakers to remove any nicks and imperfections in the wood New hand rubbed stain which is a matte walnut finish Text 214-783-4955 $500 firm. Cash only. Pickup in Lewisville. Shipping is possible, but would rather sell to someone local in Dallas because it's a PITA to ship something heavy like this. I'll have to calculate shipping if you're not in the area.

I recently finished upgrading and restoring a pair of early Heresy I's and as part of that upgrade I replaced the caps. They sounded great to me, but several members here said that replacing the caps was an essential part of the upgrade, so I did. After I took out the old caps, I measured them.....and low and behold - they measured right where they should be. Since I already had replaced the caps I left the new ones in. Now I have a perfectly working pair of original Heresy caps for sale. I'm asking $40 for all 4 caps. Local pickup in Lewisville. Shipping would be extra. Text me at 214-783-4955 Patrick

In Frisco. These have been used in a smoke-free home for the past 10 years as part of a surround system in my master bedroom. Top notch condition and they sound great. I'm upgrading to a different Klipsch set and these sadly need to go. Ad posted here: http://dallas.craigslist.org/dal/ele/5495051795.html $250 - pickup in Frisco Text at 214-783-4955 Patrick

I ran across a pair of Quartets for sale that appear to be in good condition. The problem is that they are about a 3 hour drive one-way to get them. The seller has offered to drop the price down to $150 for the pair. I have a pair of KG4s right now that are in my primary listening system and I'm almost finished restoring a pair of Heresy I's (just waiting for a set of caps to arrive) that I plan to sell. How to the Quartets compare in the lineup of Klipsch speakers?

My company sells these (or one of the other models in the same line) in every job. http://commercial.snapav.com/p-1686-wb-600ch-svce-12.aspx I especially like the small units that fit behind a flat panel TV or at a projector. For a UPS solution - we use: http://commercial.snapav.com/p-529-ep-400-ups-8htr-1000.aspx

My initial cost was very low to get them. It was from an estate sale and they didn't know what they were. I already have some KG4s in my bedroom and a pair of KLF-30s in my theater with a vintage Forte II as the center channel. I don't need them for personal use, so I've been doing what I can to get the most value out of them for resale. My cost is in replacing one of the woofers, buying new grill cloth from Crite, getting a new gold Klipsch badge from eBay and a few hours of time sanding and refinishing. I'm guessing the 150hz dip is caused from having them sitting on a bookshelf about 4' off the floor. I'm sure if I put that on the ground it would be smoother. Based on the frequency response, are the caps still good? I can replace them but would it help? Does it mean anything to the value to be able to say "with new caps"?

I wanted to compare the new driver to the original K-22 before I took it out and replaced it with another K-22 that I bought since the consensus was that the value was severely diminished without the original K-22 driver. I also bought new caps, but as a comparison I wanted to get measurements on how they sounded both before and after replacing the caps. I took measurements with 2 different RTA applications. I used an Earthworks calibration mic and a Biamp Nexia to generate the pink noise. I had the speakers sitting on top of a bookshelf that was around 4' off the floor and about 6" from the back wall. I put the mic on a stand so it was about 1 meter directly in front of the speakers. In my listening over the past couple of weeks I noticed that the new speakers sounded very similar to the K-22. I had 4 of 5 people in my office come in and sit in a chair while I turned one speaker off then the other and asked if they heard a difference between the two. Granted this was an unscientific test, but none of them could tell a difference between the two when seated about 10 feet in front of them. I have posted the RTA graphs from both software applications and made note of which one was using the K-22 and which was the new woofer. I've had comments about the speaker being work less without the original drivers, but in all honesty, which is going to sound better - a 40 yr old woofer that more than likely doesn't perform like it did when it was new, or a brand new driver with very similar T/S parameters that performs almost identical when measured? Plus the new woofer has 350w RMS power handling which is significantly higher than the K-22. Take a look at the RTAs and tell me what you think. Ignore the scale on the left. This wasn't calibrated to 1w/1m. I turned the volume up loud enough to get a good reading. The relative SPL is accurate, but not the scale. Is this response curve typical of the Heresy I's? I notice a large dip around 150 hz and another dip at 4100 hz? Is this a room response artifact? What does this say about the state of the capacitors? In listening to these, they sound bright and crisp, not like how I've read speakers sounding that needs caps replaced. I have bought new caps and planned on replacing them, but if the existing ones are still working well, is that necessary?

For something simple to build, the Eminence LAB15 in a 4 cu ft enclosure will extend to 34 at -3db while taking a lot of power (600 watts RMS, 1200 watts peak). You can get a precut sub box here for $160: http://www.parts-express.com/denovo-audio-knock-down-mdf-40-cu-ft-subwoofer-cabinet-with-blank-baffle--300-7088 The LAB 15 driver is here: http://www.parts-express.com/eminence-lab15-15-pro-audio-subwoofer-speaker--290-575%C2'> $285 The 4 ohm version is discounted right now to $199. With a 11 cu ft box the -3db point is 26. A more realistic (for me) 5 cu ft box will give a -3db of 32. I'm strongly considering building the 4 ohm version in a 5 cu ft box.

Thanks for the info. This would mean that they were among the last Heresys made before the Heresy II came out. I think I'll take a flyer and buy them. I won't be able to know about the mid driver until I get them.

I found speakers advertised on CL as Heresys (didn't say I, II or III), but the prior owner painted them black, put plastic corner guards on them and put a pair of handles on the side. I might buy them if I can find out more about their origin. The serial numbers are 158Y728 and 158Y746. I found something about the code used and from interpreting that I think the 158 means first day (or first month) of the year 85. Or that might be completely wrong and it could be the codes used for speakers from '62 to '83 using the letter format. 1962-1983 Letter format A=62 F=67 K=72 R=77 X=82 B=63 G=68 L=73 S=78 Y=83 C=64 H=69 M=74 T=79 D=65 I=70 N=75 U=80 E=66 J=71 P=76 W=81 In that case could it mean the 158th day of 1983 (hence the Y)? Anyone know what the serial number means? Thanks

Online auction. I've bought from the auctioneer before. Items are available for preview, but the location was a couple of hours away from me so I didn't see it in person. Another reason why I backed out of the bidding.

It ended at $2200. I just didn't have that much cash laying around. And not seeing the condition was scary. All I could see was a box. Too much risk, but I'd like to talk to the guy that did end up winning it.

I wish I could have pushed it further, but at $1500 I had to stop. A couple of other people were still pushing it up so I'll see where it ends.

Wow - that's a heavy turntable. It's an auction and right now the turntable is going for $750 - not sure how high I want to push it.

Yes I'm in the Dallas area. What do you think these items are worth?

Pics attached to this message. What I'm asking is what they're worth. That will let me know how much I'll offer the estate. Yes it's a Nakamichi vacuum stabilizer. Plus there is a Yamaha amp and preamp combo and the PA5 amp along with the Akai reel to reel deck.

I ran across a few items in an estate sale - all new in the box. Not sure why the guy who owned these bought them and never used them. I have no personal use for them myself, but I might get them anyway to sell. Before I put them on eBay, would anyone here have any interest? Akai GX-747 with DC-635 dust cover Nakamichi Dragon auto reverse cassette deck Nakamichi TX-1000 turntable Nakamichi VS-100 vacuum stabalizer Nakamichi PA-5 amp Any interest?
