Hi Max,
I think the situation is a little like what we went through in the States with car engine power. They changed the testing procedure and the horsepower looks a lot smaller. Still, a 260 HP '02 Mustang will run faster in a 1/4 mile than the '69 Mach 1 Mustang that was supposed to have 335 HP. I believe the new ratings are more indicative of what you'll get at home.
There have been some changes. The new squawker and tweeter in the KH/LS/B both have a little less output, but are said to be smoother. The crossovers have been tweeked accordingly.

What is the "name" of the '54 xover? Is it K-500-5000?

The T2A has more windings than the T4A. The T2A was to be used in several different speakers. You should be able to use the T4A in place of the T2A, but I wouldn't. I'd preserve your AK-3 network. You can get the T2A under a different part number from UTC in Texas. I'm sure Al Klappenberger would also sell you a pair as well. He uses them in his custom xovers. They are pretty cheap.

The tweeter WILL have a wooden horn. It has been variously described as "laminated" and "Italian". Both may apply.

How's this?

Mark,
Yes, it is the same VMPS and Brian Cheney. I have the old Larger Subwoofers. They are 17.5" x 21.5" x 39". The company is now in El Sobrante, Ca., but that may not be far from San Jose. They make what is called a Super Tower III, now. Have a look.

Thanks!

Mark?,
I use 2 VMPS Larger Subs with 4 La Scalas and a KLF-C7 for my music/HT system. The subs are powered by an Acurus A-250 that puts out between 400 and 450 watts to the 4 ohm load. I have them rolled in below 70 Hz and their level is set so that the system doesn't sound like there is a sub, unlike Circuit City.

Get a pair of Harrison Labs F-mods. They have a web page. An F-Mod is designed to plug into phono jacks and deliver a 12 dB slope for high or low pass. They are probably $10 a pair.

djk,
That sounds like good advise. not knowing the amp's particulars, I discounted clipping and the normal culprit due to the -20 setting. He might easily be overdriving the inputs, though.

Tom,
Being a former nukie (short time), I'm sort of like a reformed smoker about them. We DID need to improve our documentation and control, but we aren't regulation-driven. We're also having a really tough time getting enough boilermakers here in the South.
I like the GT jobs, too. It dissapoints me that one of our combined-cycle units just got canceled.

mdeneen,
My opinion of subwoofers has been the same as yours. However, I have made peace with my LARGE VMPS subs, partly out of necessity and partly because they work very well. As you prefer, the VMPS Larger Subwoofer is actually the bottom end of one of his full range sustems and is used up to about 300 Hz.

With the correct wood putty and sealing techniques you can patch the chips and stain and they won't be seen. I had mine done professionally, so I only have a vague idea what he did, but even knowing where the chip in the "V" was I have trouble finding it. I'm not sure I can find it after 2 years. After the staining he put on a satin polyurethane. check out the front speakers on my web site. One day I'm going to have the rears redone to match (after I buy a Combat Commander and when I have $500 laying around unused).

If you have La Scalas hooked to an 800 watt/channel amp and you keep blowing the squawker and tweeter, you're getting what you deserve! Turn it down!

Engineering became a bean-counter function when we started tracking man-hours spent on a Primevera schedule rather than work accomplished and when the nukies succeded in pushing their procedures over on Fossil Power. Now, I have to have a 37 page DCN to issue 8 engineering drawings.
If I had one employee per megawatt (2 per for a plant under construction) I could play DCNs all day!

I think Gil's right (suprise!?). I looked at the schematic for the AK-3 that a Y2K K-horn would have and I believe the extra inductor steepens the squawker's high pass and it is run without a HF roll-off, just like the K-55-V. I had always thought the -M went a little higher than the -V. Based on my experience with both the -V and -Ms in my La Scalas, I'd expect the combination of the K-55-M and Type A to be a little more forward than the K-55-M/Type AK-3 combo. That's easily cured by changing taps on the autoformer. Be sure to use Solen FastCaps or Hovland Musicaps and good inductors in your homemade Type As and you'll be very satisfied.

I wouldn't advise using the Type A in a Y2K K-horn without mods. It has no HF roll-off for the midrange. The Type A was used with the K-55-V that naturally started rolling off at 4k. BTW, the crossover points for the Type A are 400 and 9k, but all are 6 dB/octave. try adding an inductor the roll off the squawker around 5k at 6 dB/octave.
Otherwise, it will work fine.

You should take it back to the dealer for repair and file a claim with UPS. If it was not new, try 1-800-klipsch or a local Klipsch dealer.

Five Heresies and an RSW-12 or -15 would be a KILLER HT. The front 3 should be from the same year, or be modified to have the same components and network.
Yours are probably what we've nicknamed Heresy 1.5s. They have the HII squawker and HI woofer and tweeter. You need to listen to see, but I'd bet they will be sonically close to the modern HII.

The bid is now $249. The reciever is probably worth that! That is from the mid-70s and is similar the my old CA-800. It could be switched from 60 real watts (45 rated) to 8 watts Class A. It was warm and soft in the bass region, but nice sounding. I like my Acurus/Parasound gear better, but the Yamaha is no slouch.

Forbidden Planet was one of the first DVDs I bought. The first time I showed it to the boys, they were in Mom's lap (both, 8 & 10) whining when the Monster of the Id was burning through the Krell-metal door. They were so into it; it was a hoot!

And we went!
It started out with a choral concert. I didn't know what "In Association with the Chattanooga Choral Arts Association" meant until the show started. It was a little strange. One number was 3 minutes of "Halelulah". It turns out Mr. Brubeck is deeply religious and has written several choral works for his church and others. The Chattanooga Chorus is quite good, though not my cup of tea. I did enjoy the unabashed demonstration of faith.
The second half of the show was traditional Brubeck. He is soon to be 82 and grinned like it hurt for most of the show. I think he enjoyed playing as much as we enjoyed listening. The show was at the Tivoli, a 70-year-old theater that seats 2000, or so. The band was tight and polished. They did not seem to know what Mr. Brubeck was going to play next; they just jumped in as he got to a good place. i found out later, that's part of his "style".
If he comes to your town, don't miss him!

Doug,
It's -6 dB for each doubling of distance. I *believe* you get +3 dB for the second speaker or 2nd pair if they are all playing the same thing.

Be sure to listen to your choice carefully. I favor a 1983 model Heresy for your center.
