  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. I think the loudness button went away because it could never be right due to differing speaker efficiencies. I never used the button/switch type because it was always too much for the speakers I had.

    My old Yamaha integrated amp had a variable loudness control. You were supposed to set the volume control at a loud level and then use the variable loudness knob to reduce the volume from your preset level. It was a good system and with my speakers some of the positions of the loudness pot were spot on. Most had a little too much or too little compensation. By adjusting the loudness and volume knobs you could always find a setting that gave a pleasing result. Given the choice, I would like to have such a control again.

  10. Vito,

    You will want a good subwoofer to go with your Heresies. The Heresies' "quickness" and high output will require a pretty good sub to both match output and to blend in so it sounds similar. I'm not aware of what is for sale in Italy, so i can't recommend a particular subwoofer.

  11. The new tweeter is made with the T-35 tooling, but since E-V quit making it years ago, it shouldn't be considered a T-35.

    The sensitivity is -1.5 dB.

    After the change to the K-55-?, the nominal crossover point has been 400 Hz. I doubt the squawker could take over at 250 Hz when the horn's cut-off is 263 Hz. However, since the crossover slope was 6 dB/octave for most models, the squawker would certainly be active well below 400 Hz.

    I think 4500 is a better upper frequency limit for the K-55-X (aka K-55-V rev 2).

  12. The Klipsch type AA and Al's networks are both major improvements over the Type AL. I have not heard the Klipsch Type AK/AL-3, but it's design makes it look pretty good to me. I have a pair of tweaked AAs in one pair of La Scalas and ALKs in the other. I cannot decide between them. They are different and the ALKs are crisper or hotter at VHF, but that also adds a nice shimmer to cymbals. IMO, you can buy Al's networks or replace most of the components in a pair of AAs. The cost would be about the same; maybe the rebuild would be cheaper. For about half of the cost of ALKs, I replaced the caps with Hovland Musicaps.

  13. A Heresy with the same squawker and tweeter drivers would seem to be the best practical match. I'm using a KLF-C7 with my 4 La Scalas and I'm entirely satisfied. The match with the -C7 is not perfect, but it is good and it is a good size and is shielded.
