I recently acquired some vintage 1980 LaScala's. I immediately called Klipsch to order a pair of fresh K33 woofers. The crossovers were tired and I think leaking so I upgraded the x-overs. After listening to the speakers they seemed too bright and a bit shrill with a tab bit of distortion. Is the answer as simple as Do I replacing my diaphragms in all my horns or is it a problem with the x-over? Please advise. -
I bought a pair of Heresy I’s in 1979 in college that have been w/ me ever since. Type E crossovers, K77 tweeters, K55-V squeaker drivers w/ K700 horns and K-22-E woofers. I replaced the K77s w/ new ones from Klipsch about 20 years ago when I blew them and I replaced the binding posts at the same time so I could use banana plugs and lower gauge speaker cable. Otherwise everything is original. I don’t hear any obvious problems with them, but I want to restore them to their former glory or better. I’ve been reading everything I can find here and at Crites and at ALK but I still have many questions and would appreciate advice. 1) I know I need new caps and since I don’t solder, I plan to replace the crossovers. I could use Crites Type E, which uses the same spec as the original, or ALK’s universal CSW which have some upgrades. A few questions about that: - I understand what Al says about constant impedance and no resistive error, but I don’t use an SAT amp so does that matter to what I hear? - Also, the Type E only uses a low-pass inductor for the woofer. The squawker and the tweeter use high-pass capacitors in parallel, so (if I understood Al’s site) high freq sounds that should only go to the tweeter go to the squawker too. Does that matter? Would it matter if I replaced the K77 tweeters w/ Crites CT120s? - Are the actual crossover frequencies the same between the two networks? It looks like maybe there is some adjustment possible on the CSW but I’m not sure. 2) Is upgrading the K77s to CT120s a good idea? 3) I know I need to replace the gasket between the squeaker driver and the squawker horn, but does it also make sense to upgrade the K-55-V with a Crites A-55G? Do squawker drivers wear out and/or is the A-55G a lot better? 4) Crites offers CW1228 woofers as drop-in replacements For the K-22-E. Are they better, especially given that the K-22-Es are 40 years old? Or what if I just rotated the K-22-Es 180 degrees as I read somewhere? Sorry about so many questions - I’ve read a lot on my own and I’m still not clear on the best way to do this. There is tremendous expertise here and I’d be grateful to tap into it. Thanks in advance

Hi all! This has probably been answered somewhere before, but I'm not finding it. I'm looking to tri-amp a pair of 1988 Heresy II's I just picked up, and to do the Heresy II->Heresy III conversion on them, and then tri-amp them again. Does anyone have the Heresy II and Heresy III crossover specs? 1) What are the crossover frequencies and slopes? 2) What's the attenuation (padding) of the different drivers? 3) Are any of the drivers polarity inverted? These would be different for the Heresy II, and III -- and I'm looking for both sets of data for before and after the conversion. Thank you! -
