Bernie Lenti Posted February 9, 2003 Share Posted February 9, 2003 I've recently purchased a pair of La Scalas and was wondering exactly how old they are. Their serial numbers are 8642663 and 8642647(or maybe A7)? They have the square magnet on the K-77's but mine don't say K-77M as I've read in other posts. Are they the same as the K-77M? I also wanted to know about the crossovers. They are the AL model which I've read here are not known as "the good ones". Which would be a better model and what would that better model do towards creating better sound? If I can improve their sound, and that seems hard to believe since they sound so good already, I will. I already own an Electro Voice Georgian and a Patrician IV, so I can appreciate listening to the best sound possible. Thanks for all your input. This is a very helpful and informative site.

HDBRbuilder Posted February 9, 2003 Share Posted February 9, 2003 your LaScalas were made in 1986 Quote Link to comment Share on other sites More sharing options...
JohnA Posted February 10, 2003 Share Posted February 10, 2003 You should change to the type AA, ALK or Type AL-3 networks. the choice is pretty much yours and depends on whether you think the oil-filled motor-start capacitors sound better than the newer Hovland/Solen caps. I like my Type AA with Hovland caps as well as the ALKs. Quote Link to comment Share on other sites More sharing options...
Bernie Lenti Posted February 10, 2003 Author Share Posted February 10, 2003 Thanks to both of you for the info. I had a pair of La Scalas that I sold last summer that had the AA crossovers in them. I should never have sold them. I missed them so much I bought this pair I have now. I thought I noticed a difference in sound but thought it must have been my imagination. Who knows, maybe it is, but I'm pretty convinced after what I've read on this forum that I could get better sound upgrading and getting rid of the ALs.

Tom Mobley Posted February 10, 2003 Share Posted February 10, 2003 I have a set of factory AA's available for sale. I believe they're early models. I've used them in a pair of DIY La Scala's, as far as I know they have no issues. I built a set of Al K's, I'm sticking with them. Email at tmoble@earthlink.net if you're interested. I'll see if I can get a picture of them. Tom Quote Link to comment Share on other sites More sharing options...

Bernie Lenti Posted February 13, 2003 Author Share Posted February 13, 2003 Hi Kim, My mids are the K-55M. I have several older alnico EV T35's and was going to experiment with installing them to see if there is any difference. I haven't opened up this set of La Scalas yet to see what woofer is in there.

Bernie Lenti Posted February 14, 2003 Author Share Posted February 14, 2003 They are ElectroVoice T35's with the round magnets. I have some 16ohm and some 8ohm but I would only use the 8ohm in the LaScalas. Quote Link to comment Share on other sites More sharing options...
