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,

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.

Audio first! I've seen small video with $30,000 of audio (Jubilees!) and I forgot there was even a screen. I was mentally in "The Matrix".

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.

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.

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).

Aren't those high-grade caps beside the tube?!!

The "New" Heritage speaker have new squawker and tweeter drivers and a network adjusted to account for the 1.5 dB difference in efficiency of the new drivers.

That's sure a hoot!

Carver/Carver designed amps are the last choice I'd make for horns. I'd even buy tubes before Carver.

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.

They are unfinished birch with the optional upper grilles. The crossovers are Type AL, the worst in my opinion. They look mint and unmodified.

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.

Infinities are well known to be "hot". It is the reason I can't stand to be in the room with them.

Gil,
Yes, my La Scalas have Type AA networks. I do hope they have good output above 400 Hz. I'm going to experiment with an Altec driber and a pair of 511Bs I have when I find a deal on the drivers. I need to arrange to go over to a coworker's house and have my bass horns tested to see how high they do go. I seem to always be too busy to remember to do it. 800 or 900 Hz would be great!

You are correct that the bass response is largely defined by the size of the horn and that the increase in impedance is due to the horn as well. There was a magazine article that discussed the difference in response between the 2 slot sizes, It was quoted on this forum. Look back in messages about 3 months old. The conclusion was there was only a little difference. Over the years the K-33 has been tuned to be the best performer in the Klipsch bass horns. It's happy coincidence that it's cheap. PWK used some of the best woofers made in earlier days. If one was better than the K-33, I'm sure it would have been used in the late models.

Gil,
Being the pragmatic engineer we know him to be, why was the inductor put in the crossover if it was not needed or if response was better without it? Would it be something related to providing a uniform impedance for the amplifier?
I've read about this before, but never was tempted to try it until now.

It looks like you should set the Heresies to small.

1. What Heritage speakers have you owned, currently own, or want to own? 4 La Scalas
2. What was your age when you first purchased a Heritage series loudspeaker? 42
3. What is your current age? 45
4. Why did you choose Heritage loudspeakers over another Klipsch model? The sound I heard in 1975.
5. If you currently own some Heritage loudspeakers, and could purchase some more Klipsch speakers(new or used), which ones would you purchase? Why? K-horns; The sound I heard in '75.
6. Do you think the upcoming Jubilee should become part of the "Heritage" line, since it was also designed by PWK? Yes!

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.
