Al's crossovers primarily use better components. In fact, they are pretty much the state of the atr, hence the price. The crossover points and slopes remain about the same as the AK/AL-x series. The tweeters have less protection, but fewer components to interfere with the sound. The impedance curve is pretty well flat from about 80 Hz to 20k. Al uses a trick with a resistor to control the impedance in the midrange so it doesn't get so high. That should be good for tube amps. The Klipsch networks tend to have more losses in the tweeter circuit so Al's networks sound a little hotter. I prefer them to the Type AL by a long margin. John

I see new drivers and different crossover frequencies! The K-horn and Belle crossover to the squawker is 450, but the La Scala is still 400, curious. John

According to BobG, some time ago, the tweeter in the C7 is actually turned wrong for horizontal use. If you turn the speaker on its end, vertically, the tweeter has the intended dispersion pattern. He encouraged me to look at a pair of C7s for my rear channels. I founs a second pair of La Scalas cheaper, in the end. i say go for it! John

It looks like Tom has several nice money pits! My favorite Colt is a Series 80 Satin Nickle Gov't, Model. I've only seen the one. Most people have never seen one. I also have a DW 41V with 4" and 8" bbls. Shoots great! I could never get a handload to work well in it, though. I always had unburned powder left and poor groups. When a Ruger Blackhawk in .44 Mag. hurt my hand, I bought the .41. It turns out a .41 Mag. has more energy than some .44 loads. John

O.K. Dean, Let's have it, Dish. I remember BobG mentioning the Super Klipsch, but I thought that was the Jubilee. Tell us about elaborate cabinet designs! John

Jobman, Somebody on the BBS wanted a single walnut Belle, would you? John

Rush is a Liberal! Not me! I'm also partial to Colts, but 1911s. The OACP makes a great tool for CCW. The AWA Peacekeeper does look like a lot for the money. I understand a Custom Shop Colt goes for about $3500. I have a little of everything from the attached BP replica to the 1911s mentioned.

Mislabeled, sort of. These will go cheap. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1344408545 John

Boy, I hate you had to sell one of your handguns! That sucks! John

In those years the Cornwall II had the horns turned 90 degrees so they would have a lower profile; kind of a low-boy. John This message has been edited by John Albright on 04-06-2002 at 03:35 PM

Use a multimeter and check its DC resistance. It should be about 3/4 of its rating. It it's infinity you have an open voice coil and need a new diaphragm (assuming it is replacable). John

Production is not scheduled until mid-April. There is information about the new Heritage out "there". Essentially, Klipsch is going back to the future with the lone. New versions of the K-55-V and K-77-M will be used and a new crossover network is required. K-horn is to be issued first, La Scala next, and Belle and Heresy later. Heresy III would be a good development name, but I don't know what the official name will be. The bass horns and squawker horns were not changed. R&D on the drivers and crossover caused the delays. There was apparently some difficulty at the OEMs. I have some theories as to what may have been going on, but no facts. The new drivers are said to be smoother and the result is a warmer speaker. A retrofit kit is also expected some time in the future. John This message has been edited by John Albright on 04-06-2002 at 12:57 PM

The Heritage Series is still made. Production was restarted this month after about a year's hiatus for a driver replacement and crossover redesign. I think most of the time was to allow the OEM to do some R&D on the drivers and to let its ownership settle down. John

The Klipsch Tech probably meant it can put out 130 watts/channel. John

Well, he didn't say "passive bi-amping". JohnJohn, you might try Harrison F-mods on the inputs of your amps for the crossover. They are only in 12 dB/octave and in discrete frequencies, but you can get high and low pass at the same frequency. John This message has been edited by John Albright on 04-04-2002 at 01:12 PM

Yes, It is! It's shown in the proper placement for the older CII. In that position, the long axis of the horns is horizontal. Note the riser on the bottom, often thought of as the "side". John This message has been edited by John Albright on 04-09-2002 at 12:19 PM

You need an electronic crossover. It goes between the preamp and the power amps. You should use the same crossover frequency and slopes in the original crossover. John

NO. The 50 watt rating is for a continout load. You will not put 110 watts from your receiver into the speakers. The distortion would be horrible. John

If I were going to build my own cabinets, I'd build a "J"-shaped bass horn sometimes called a scoop. Mr. Paul designed one and published it in a paper I have. It would be taller than a La Scala, but I believe it could have a lower cutoff frequency and therefore deeper bass response. You'd use the rest of the La Scala components as is. John

You can certainly install 2 new K-33-Es from Klipsch. Al Klappenberger has a crossover designed for the Cornwalls. You MIGHT even get Klipsch to construct a new set of the correct crossovers in the lab, but I doubt that the originals are bad. Are they leaking or are the terminals corroded? John

I've seen pictures in a Klipsch brochure of the first Cornwall IIs laying on their side so that the horns were horizontal and the pair was symetrical with the horns to the outside. It was sort of a lowboy configuration. That picture also showed a "normal" pair of Cornwalls. The old Cornwall IIs are rare. John

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1341159358http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1341893486 Look at these. John

Rat shack sells crossovers. It won't be that simple, though. The horn is much more efficient than the woofers, so the crossover needs built-in attenuation. The best thing to do is to rebuild the originals with superior parts of the same value. John

Hi Ray, How're you doing? John

The only omportant part of the xover that would be affected by corrosion would be the connections. Unscrew them and clean the terminals and that's all they'll need. I have ALK xovers and like them a lot. I think they are a bit better than the Type AA and miles better than the Type AL I had in one pair of my La Scalas. they are said to sound a lot like the type AK-3 and by inference the Type AL-3. As for the cabinets, only a cabinet maker can tell you how much they need to have done to them. By your description, it sounds like little or nothing. The drivers will not require rebuilding unless insects or rodents have damaged the woofers. The first step looks like getting them out and giving them a good cleaning and oiling with lemon oil or other good furniture oil/cleaner. I think you answered your own question about a sane expenditure. You might also call Klipsch and price a new pair of bass horns or a even a new pair of complete cabinets. There are authentic plans out there you could use to have a cabinet maker build you a set as well, but the bass horn is a HUGE amount of work. These last options are in case your cabinets are beyond repair. John This message has been edited by John Albright on 03-27-2002 at 03:40 PM
