I missed the nailing part. That Sucks!

You will likely have 10 times the power needed for Klipsch speakers. Since you have RP-3s I doubt bi-wiring will provide any benefits at all. The woofer is self powered so you essentially have a bi-amped speaker system with only one set of speaker cables,

There is no cutting required to get the woofer out of a La Scala. The botton plate unscrews and comes off.
The only place to get K-33s is from Klipsch. Eminence cannot sell them directly. Klipsch only charges $110 each.

The new squawker and tweeter are both less efficient and have a little less max. output. The difference in efficiency is about 1.5 dB, I'm told. They may not have the power handling capability the old ones had.

M.H.,
There cannot be too much difference between the La Scala and Belle. The Belle squawker crosses over 100 Hz higher than the La Scala's 400 Hz. In many years both used the same crossover and they have always used the same drivers in the same year. I lack proof, but I believe the Belle's bass horn is capable of going higher because the effective bend radius is longer than the La Scala's (it is bent more gently). That should make up for the shorter squawker horn. That shorter horn should also be less prone to ringing since it shorter length makes it effectively stiffer.

It would depend entirely on the ribbon and horn in question. The Heritage tweeters only go up to 17K.

You'll have to move the RC-3 farther from the TV. You need to do it just to comfirm the TV is inducing the hum in the speaker. Also try rerouting the speaker wire to the RC-3.

As best as I can remember, it's about +15%.

The K-55-X is so close the the late K-55-V it would scare you. They are still using the K-401 horn. The throat hasn't changed, it's still 1" and the voice coil is still 2". I'll bet that is what you saw. The K-55-X is made by the same outfit that made the K-55-V, but has a new name.

Hi B,
I think I saw him! Just wait till I get to complain about my flickering power switch and hissing processor!
Just kidding! When are you moving? A commute that long stinks!

As long as you don't drive the car amp into distortion there will be no damage at all. However, power amp ratings on car amps are notorious for being overstated. In addition, car amps are rated at 4 ohms or even 2 ohms, but your La Scalas are about 8 ohms.
A car amp rated at 150 watts per channel into 4 ohms would pull over 17 amps. Does it have 2 10 amp fuses? If not, it won't put out 150 watts/ch.
Assuming typical peak power ratings, a 150 watt/ch amp will put out 37.5 watts RMS into 4 ohms and half that into 8 ohms. 19 watts/channel will not make La Scalas rock outdoors. 37.5 watts is about 3 amps into 4 ohms. Does it have two 3 or 4 amp fuses?
Still, as long as you can't hear distortion, you won't hurt anything. Should you actually have 150 watts RMS/ch, you will have plenty of power, as long as the battery lasts.

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.

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.

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!

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.

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!

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

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.

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

In those years the Cornwall II had the horns turned 90 degrees so they would have a lower profile; kind of a low-boy.

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).

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.

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.

Mungkiman,
Can you post pictures? I can scan and post photos if you want. La Scalas ARE nailed and glued together, but there is a woofer access plate on the bottom that is held on with 12 screws. It looks like a riser to some. Are they black lacquer, or covered in black wrinkled vinyl? What is the model name, LS-BR, LS-BL, LSI-xx? If so, the access plate is the bottom plate. No cutting required. I've never seen the bottom of an LSI, but *Klipsch* would never have made a speaker that couldn't be serviced.
