The BBS is full of discussions about tweaks. Search the Updating and Odds & Mods sections for damping and tweaks. John

I think the Type AL-3 is a pretty good design. It has a pair of wires that must be cut for bi-wiring. I have a schematic of it, but it is too big for the Forum. I'll try e-mailing you a copy. John

Which Network do you have? The Type AL-3 was designed to make bi-wiring easy. The rest will be harder but not impossible. John

That sounds a lot like a bad, or misaligned diaphragm. John

The K-43 woofer is what you want. It is designed to be used with the back air chamber volume and the slot size in the throat of the horn. It is sometimes said to have 2 or 3 dB more output than the K-33. John This message has been edited by John Albright on 12-07-2001 at 01:34 PM

Start off by using the original crossover slopes. I don't know which squawker you have, but for the K-55-V and Type AA network, the bass is rolled off at 6 dB/octave above 400 Hz, the squawker is rolled in at 6 dB/octave above 400, has no upper roll off and the tweeter is rolled in at about 18 dB/octave above 6000 Hz. I say about because the high pass filter on the tweeter is not an ideal Butterworth. It has a "bump" in the response of a dB or so at 6k. I believe this is an attemp to EQ the system and make up for the K-55-V's falling response at 6K. The K-55-M doesn't fall off at 6k like the -V does so I believe the networks for that driver roll off at 12 dB/octave above 6k. John

In some models, especially the Belle and K-horn and maybe the Heresy, consecutive serial numbers ensure the wood's grain is "matched". I believe matched in this sense means opposite-hand (mirror image). John

There are a few DIY things you can do for the speakers. Search the BBS for horn damping and cap. There have been many discussions about the Heresy. John

I don't understand all I know about Tratrix curves, but in general, a good quality compression driver should be able to cover 700 to 17k+. It and the horn might not fit into the cabinet, though. John This message has been edited by John Albright on 12-02-2001 at 06:20 PM

You'll get better answers in the ProMedia Forums. This is Home Audio. I think you'll have to listen for yourself. John

The Type AL crossover started in 1982 or perhaps late 1981. John

Karen, you could search the BBs for ALK Crossovers and look here: http://www.alkeng.com/xocomnt.html John

The power ratings are maximums (and without significant distortion at that). You should never use that as a guide to your amplifier size. A Quintet probably should not see more than 25 watts continously or if will fry. John

One pair of my La Scalas is 20 years old and did not "need" any updates. I have modified them slightly, but many would say it wasn't needed. The speakers hold up VERY well for dozens of years. John

I use a KLF-C7 as my center channel with La Scalas as mains and surrounds. The C7 is a pretty good match, if not perfect. A Heresy from the same year would probably be better. I was looking for Heresy surrounds when I found the rear La Scalas cheaper. I use a pair of VMPS Larger Subs driven by a power amp that supplies about 400 watts to each one. When in the corners, they can keep up with the La Scalas. At sane volumes and below their distortion is low enough that they blend well with my La Scalas. Your biggest problem is going to be finding a sub(s) with enough low distortion output to keep up with La Scalas. John

The reason DD is the dominant audio in theaters is advertizing. It's the same reason Bloze sells the most speakers. John This message has been edited by John Albright on 11-28-2001 at 01:23 PM

What are you doing in Morocco?! I love the food and hope to go there myself someday. What about traveling to France to buy Klipsch? Or Spain? John

A small amount of difference is often the voice coil rubbing, probably due to excessive heat. For a really large difference in output I'd look at the crossover for bad solder joints or bad components. first swap the K-55-V from one speaker to the other. If the low output moves it's the driver. You should be able to get it overhauled for about $75. John

Ray, The published graphs of the La Scala I have show it is at least as smooth as the K-horn above 60 Hz. Below that the response drops like a bluff. The La Scala has a 1 or 2 dB hump about 200 Hz that would make the La Scala sound a little "warmer" than the K-horn, but they are remarkably similar in response (above 60). The 45 Hz rating seems iffy. John

Ross, I think you're seeing shadows and reflections, too. John

PhilH mentioned several months ago that ferrofluid is so common now nobody bothers to mention it. I believe he said Klipsch has used it in selected drivers for some time. John

The B is not part of the SN. The N indicates 1974, if I did my math correctly. It should have been a good year. They should have Type AA networks, one of the better designs. John

Thanks! John

65 wpc is enough to push ANY Klipsch speaker. The better question is is the amp of high enough quality to sound good? John
