Normo Posted September 1, 2008 Share Posted September 1, 2008 I am new to this forum-this is my first post. I hope this is the right forum. I just picked up a pair of La Scalas that I think date from 1983. They sound great but there is a little boominess in the midrange that maybe due to old out of spec caps, room acoustics-its on wood over concrete, or cab vibrations. It could also be the amp I am using. I am trying them with my kenwood KA-907 which matches well with JBL 4430s but may not be the best match for these speakers. I don't want to ruin the "magic" that is still there-any suggestions on where to start? Thanks Norm Quote Link to comment Share on other sites More sharing options...
ricktate Posted September 1, 2008 Share Posted September 1, 2008 I would re=fresh the caps nd get some Grippers from wal-mart they help alot i think and make sure you put one in center of acess door on bottom.Rick Quote Link to comment Share on other sites More sharing options...
Normo Posted September 1, 2008 Author Share Posted September 1, 2008 Thanks for answering. Two questions if I may. What are "grippers"? And as a newbie, do you know of a source of what the caps are on the AL crossover? Thanks Norm Quote Link to comment Share on other sites More sharing options...
BEC Posted September 1, 2008 Share Posted September 1, 2008 Norm, Welcome to the Klipsch forum. I would suggest that you replace the Type AL crossovers rather than rebuild them. That crossover is (in my opinion) not one of Klipsch's best efforts. Bob Crites Quote Link to comment Share on other sites More sharing options...
Marvel Posted September 1, 2008 Share Posted September 1, 2008 Norm, Welcome to the forum, and congrats on getting some LS. I replaced the AL crossovers in my LS with some I built, and the difference was astonishing. I whole heartedly agree with Bob about replacing them. We always like pictures, to see what folks have purchased. But no matter what, just enjoy for a while. Bruce Quote Link to comment Share on other sites More sharing options...
Islander Posted September 1, 2008 Share Posted September 1, 2008 Welcome to the forum and congrats on getting your La Scalas! I discovered this place after I bought a pair of 1974 La Scalas and met many new friends, along with learning a great deal about all things Klipsch, as well as lots of audio info. You'll find that your speakers can be made to sound better and better and this is the place to find out. Quote Link to comment Share on other sites More sharing options...
Normo Posted September 1, 2008 Author Share Posted September 1, 2008 Thanks for the replies so far guys. I checked into what I have and the idea of new x-overs sounds good to me. I have a K-77M tweeter, a K-55M mid, and a K-33E woofer. The x-over is type AL and they date from 82 or 83. What type of cross over replacement do you recommend,.

joeydingo Posted September 1, 2008 Share Posted September 1, 2008 Spend a short period of time checking through posts on this the forums here and you'll find Bob Crites is about as honest, skilled and knowledgeable as you're going to get for a reasonable price (or even a higher price). He'll either sell you the kits to build/rebuild crossovers yourself or give you drop in units. My dealing with Bob were A+ all the way. I'd also second his opinion on the AL crossovers not being Klipsch's best effort and would also suggest you consider replacing them. I know there are other people here who offer similar services, so no slights intended. Quote Link to comment Share on other sites More sharing options...
bliss53 Posted September 2, 2008 Share Posted September 2, 2008 More good words about Bob. He sent me tweeter parts, caps and grill cloth for my DIY projects. His advice on what to do and how to do it was very helpful.. Quote Link to comment Share on other sites More sharing options...
Marvel Posted September 2, 2008 Share Posted September 2, 2008 What type of cross over replacement do you recommend That should open a can of worms...[*-)]Some say that simpler is better, and that is kind of what I did on mine. A first order (6db per octave) between bass and mid driver, with second order (12db per octave) between the mid driver and tweeter. Mine is also a constant impedance, so my tube amps like it a lot. Some say these are also better for low power or lower listening levels. Bob's A and AAs also fall into this category (making new versions of the originals). You can get extreme slope crossovers (up to 100+ db per octave) to almost totally isolate what each driver reproduces. There is only a very small amount of interaction between the driver's outputs this way. Some love these versions (popularized by Al K), although the general thought is that these need to be cranked a little to sound their best. YMMV Or, you can go crazy and tri amp thing with active crossovers and separate amps. Some of this may depend on the music you like to listen to and what your current amplification happens to be.

kg4guy Posted September 2, 2008 Share Posted September 2, 2008 I would just stay with type A they sound very nice and are not alot off money you can get them from Bob Crites for under $200. shipped Quote Link to comment Share on other sites More sharing options...
BE36 Posted September 2, 2008 Share Posted September 2, 2008 Welcome to the forum. I have Bob's tweeters and ALK type B crossovers. This combo sounds great - musical highs with out all the static of the old 77s and the JBL Baby cheeks that I tried. For 2 channel I am running an Adcom 700 CD player with variable outputs directly to an Adcom GFA-535 II, no preamp. Sounds great for very little cash, less than $400 for both, until I can afford/demo a tube preamp. Quote Link to comment Share on other sites More sharing options...
