I have an answer. The Rollerblocks are Bullshit! (excuse my expletive)
It cannot be both a coupler and a decoupler.
It does NOT use earthquake foundation technology. Earthquake foundations use springs and/or viscoelastic isolation to limit the energy transmitted from the ground the the structure.
Powercords with RF filtering in an environment rich in RF AND connected to a REALLY poor quality power supply would provide a definite benefit. Otherwise, the benefits are entirely psychological. Think about it. How could a teflon water hose provide better water than a viton water hose? That's all a powercord is, a water hose. Once the voltage is changed by the transformer, rectified and filtered by the capacitor bank, there is nothing left of the original AC wave. I assume that the power supply is well made and not one in a Pioneer component.

There is one thing a 3-way Klipsch horn-loaded system CANNOT suffer from and it's Doppler distortion. Horn loading and small diaphragm movements prevent it.
A 2-way monitor with a 6-inch "woofer" crossed at 2k is the prescription for doppler distortion.
Credibility blown.

I have heard the KLF-20s and liked them. I have 4 La Scalas and a KLF-C7 for my HT. I think you'll find the KLF-30 have boomier, deeper bass. You may miss that aspect of the KLF-30s after switching to the Belles. OTOH, the Belles will be cleaner and purer sounding. They will sound more realistic. Acoustic bass notes will be presented as clean and accurate so that you think the instrument in in the room.
I also think you're characterization of the Legend and Reference series a bit harsh. You own several of them, have they been that bad?

Tom,
I saw the pics of those K-horns. It is not a factory mod and the closed backs are not long enough to finish the bass horn, so deep bass performance will suffer if not placed in a corner. The mod seems well done and it will likely make it easier to achieve full performance in a corner, but it is not enough. A K-horn needs 4' from the apex of the corner out along both walls.
I believe the reason Mr. Paul did not enclose the ear of the k-horn was because of other patents and the fact that it was not necessary since it was to be placed tight in a corner anyway.

Yes! It does ring a bell. I prefer the much praised "Hell Freezes Over" in 2-channel over DTS 5.1. I would be very pleased with 3.1 channel movies, even.

Driver, box and port size are all interrelated. I once came by a JBL woofer and tried to make a subwoofer out of it. I could get -3 at 25 Hz out of a ported box the size of a refrigerator. It was very efficient, though.

Oops! All Cornwall drivers are 4 ohm K-33s used in the KH/LS/B.

XP Sux! Use the Mac or Linux. We've had nothing but trouble since we converted to XP at work. Mine crashed twice in the first 2 hours I had it. There's no more "blue screen of death", it's grey!

How loud are you playing when this happens?

I suggest soft jazz, flowers and a carafe of lemon oil.

Stumped,
The difference is compression in the drivers. NO speaker has linear output from 1 watt to max. power. The new frequency bandwidth is most likely from a different testing technique. The older K-horns were said, by Mr. Paul, to be linear up to 63 watts. After that the double the power and get 3 dB didn't work. Heresies would not be linear through as wide a range.
You are not seeing something new. You have just discovered something you didn't know. So far, the HIIs have the same drivers your HIIs have, but that may change, now that the new KH/LS/B drivers are in production.
Klipsch only makes a few if its own drivers, not all.

That sounds like a good enough price to me. The tweeters could be repaired for a little as $26 each, if you can replace the diaphragm yourself. Klipsch will replace them (and probably test the repair) for $75 to $80 each. The gough will have to be filled, sanded and refinished. I have no idea what that might cost. If the finish is dark you'll have a better chance of making it match. I think Gil is right about the crossover; it's probably good. Those tweeters have a continous rating of about 2 watts and a peak rating of about 10 (I've been told several values). djk says the newest replacement diaphragms have a bit higher rating, but I can't remember the value. He's usually right. The other drivers are pretty tough, they should be fine. Listen to them to be sure. An overhaul will be in the $75 to $100 range each. Check the bottoms of the cabinet for water stains and/or delaminations. If there are any, walk. That's too much wrong to be worth the trouble.

Oh, I LOVE the look of the Avantgardes! Many people say they sound really nice, too. They ought to.

I use Parasound amps with my La Scalas. I am VERY pleased with the results. They are very clean, neutral and keep a vice-grip control over the woofers. I use a 1203A and a 1000A. The 1203A operates in Class A up to about 1.25 watts and the 1000A up to about 1.6 watts. With La Scalas, that amounts to loud! I recommend them.

You dont identify the age of your La Scalas, but IMO, the late 70s models with the Type AA network (and K-55-Vs with solder terminals) are the most desireable because they sound better. The difference is small, but there in the lower treble region. I bought one pair of my La Scalas of of E-bay for $450. They had a loose wire. The other pair I bought out of the paper for $1000. They were unfinished. Depending on real condition, They should go for $800 to $1200. I think you'll get the highest price for them on ebay.

Sorry Builder,
I have 2 La Scala grille kits from Klipsch. They are a removable fiberboard panel covered with Heritage cloth and held onto the cabinet with Velcro. The full kit includes 4 pieces of birch quarter-round to be placed around the edges of the HF horn section. I ended up with 2 because I decided to change the finish color of my rear pair.

You're hearing analog!
In spite of the limited dynamic range (severe on some of my rock LPs), surface noise and inconvenience, Vinyl does sound better.

Warren,
You are a Hoot!

There are at least 4 screws holding the network; keep looking. I think some have used audiophile wire on their K-horns. I can't remember too much about the results, though. It seems like nobody hurt the sound, but I don't recall much help either. Try it for yourself. I can't imagine degrading the sound unless you don't use enough strands of magnet wire.

F*********p got himself banned. Nobody put a gun to his keyboard and made him type that stuff. We are responsibile for our own actions and not for the actions of others. No one *forced* F*********p to be a jerk. No one forced him to use the sig he did and that was too far over the line.

The pro Heresies are ported, but it kills the deep bass. The Pro versions are more efficient, but ...

I used to use iescrow.com. They held the money while I got 3 days to evaluate the merchandise and then they released to money or I sent it back. The seller had to get his stuff before I got my money back. It worked great! Sadly, they are no longer in business. I thought E-bay had a similar service available.

It's a Torx bit. You should ba able to buy them at any auto parts store.

2 Heresy's and a C-7, now what?

For surrounds look at the SS-1s. i think you'll like them and they are relatively small.
However, you need a subwoofer first. A 3.1 movie system will be quite satisfying and you don't realize the very low bass you are missing. There are lots of good subs out there, but don't even consider anything less than 12" and 250 watts. You need a great sub to keep pace with Heresies and that -C7.
Want cheap, look at this kit (smaller subwoofer) and a power amp: http://www.vmpsaudio.com/ps2.htm
