I guess that's burning one! John

Heresies about the age of your Cornwalls, so they have the same squawker driver and tweeter, would be the best. I use a KLF-C7 with my La Scalas and it matches well. John

The K-55-M was used by Klipsch until this year. E-V may not have made any new ones for several years and Klipsch may have been using stock-piled drivers. John

Someone will have to take the lead and organize the trip. That someone will have to write some letters and e-mails to pull the trip off. I may just come back for another trip to Hope. The last one was a blast! John

If there was a Type AL-2, I don't have it, but I have a copy of the others. I like the Type A and Type AA best. Watch the mail. John

More Heresies would be the hot ticket! If you can't work in more Heresies, A KLF-C7 will work well for a center and I'd look at RS-3s for surrounds. I use a KLF-C7 with my 4 La Scalas and it is a pretty good match. John

The RSW-15 was VERY impressive when used in a 5.1 system with Jubilees as mains, K-horns (or a series of Heresies) as rears and a Belle as a center. It had the output capability to match the Jubilees. When pushed really hard, its distortion was probably higher than optimum, but it was not objectionable. At sane levels it sounded nice and it could move air! I'd have one. John

One good speaker wire per speaker is enough. Biwiring is running 2 wires from the same amp terminals to each speaker. The speaker must have 2 pair of terminals for biwiring. One pair connects to the woofer only and the other pair connects to the high frequency drivers. The theory is that large current flow in the bass cannot affect the high frequencies because they are carried in the other wire. I do not believe it is audible. John

Tom is generally correct. You will enjoy the addition of subwoofers if they are high output and low distortion. I use 2 VMPS Larger Subs with my La Scalas. The subs are placed in corners and powered by an Acurus amp capable of more than 400 watts/channel. They seem to keep up pretty well and the distortion is low. The Larger Subwoofer has a 12" and a 15" active driver and a 15" passive radiator that's slot-loaded. John

I have a poor copy. If you want to analyze yours it will be O.K. If you want to build a pair, it won't be much help. If I were you I'd build a pair of Type As or Type AAs. The Type ALs sound pretty rough. They have a midrange ring to them that makes French Horns sound like a howl. John

Do your calibrations while seated in your "sweet spot' with the meter pointed at the ceiling at a 45 degree angle from vertical and facing the TV. Don't point the meter at any speaker. John

Watch your Language! We don't need that kind of stuff here! John

30 years? John

The square tweeter is a K-77-M. It was probably a replacement for a defective K-77. The K-77-M has more and smoother VHF performance. Only damp the back (out) side of the horns and don't remove the tweeter's magnet. It isn't supposed to come off. John

You'll get a better answer in the Promedia forums. It does sound like an amp failure, though. John

Ross has a valuable suggestion that will improve the value of the BBS. I like it! I especially like the voluntary, self-policing part of it. John

Those are VERY new, so $400 pretty well qualifies as a steal. They would have sold for ~$1100 a pair. John

The number you provided is the serial number. You have a pair of 1981 Heresies. It should have been a good year. John

Klipsch designed the Z-bracket to flush mount the tweeter in a Belle and K-horn. They require a larger hole for the tweeter so it can fit through to the front. The the Z is used to screw the tweeter to the back of the motorboard while holding it forward flush with the front of the motorboard. It will also work on La Scalas. I con't recommend them for Cornwalls or Heresies due to the cabinet seal that's required. John

What is the serial number of your La Scalas? Which Type of xover do they have (AL-3)? I can e-mail you a schematic of the AL-3, AL & AA. John

Exactly! John

The DC resistance of the K-33 should be 3.2 to 3.6 ohms. John

It should be 3,500 Hz to 17,500 Hz. However, based on the response plots I've seen of the Heritage line, I'd call it 3,500 to 15,000. John

Ross, Yes, I did it to my front La Scalas to the squawker opening. I went to Home Depot and bought their heaviest self adhesive felt and cut it into 3/4" strips. I stuck that to the edges of the plywood where the squawker horn "looks" through. I disassembled my tweeters to front mount them; don't do it, get Z-brackets! It's been so long I can't remember how it affected the sound. I don't think I did that much for the squawker. John
