Kiwi Boy Posted July 27, 2007 Share Posted July 27, 2007 Hi everybody I put an ad in the local paper wanting old speakers and a guy answered, he was leaving the country and couldn't store his speakers. All i knew about Klipsch was that they were famous. I went listened to them for about 2 seconds and arrived home with them and a Huge old KT88 valve power amp. I would appreciate some help identifying how old they are if possible. They have AA crossovers and the back label states they are LS-BR models. Any advice hugely appreciated?

Arky Posted July 28, 2007 Share Posted July 28, 2007 Lascala birch raw. Those will clean up nicely. What are the accompaning serial #'s on the back label? Congrats & welcome! Quote Link to comment Share on other sites More sharing options...
Kiwi Boy Posted July 28, 2007 Author Share Posted July 28, 2007 Hi, The serials are 185616 and 7p037, is there a reasion why the #'s are hugely different? Cheers. Quote Link to comment Share on other sites More sharing options...
Dflip Posted July 28, 2007 Share Posted July 28, 2007 On the back, either on paper, or engraved, there should be a number. If you post that number, then some of the members here should be able to tell you how old the age of your birch LaScallas. Make sure you asked the seller when the amp was last serviced, some of the caps and/or tubes could need replacing. If the amp is okay, listen to the speakers and then they probably could use a capacitor replacement in the crossovers. You will like the sound, tubes and Klipsch go very well together. Just remember that LaScallas only go down to 50 Hz, so depending on how much bass you want, a sub might help round out the bottom end. The treble and mids will sound awesome.

DizRotus Posted July 28, 2007 Share Posted July 28, 2007 Welcome. Your La Scalas look great. Use the search function to uncover many threads regarding the serial numbers, AA crossovers, etc. pertaing to La Scalas. After you enjoy them for awhile, I suggest that, at a minimum, you replace the old capacitors in the corssovers. The path of least resistance is to contact BEC on this forum for the updated parts.

Dflip Posted July 28, 2007 Share Posted July 28, 2007 Some information on crossovers: my guess is one of the speakers is P - 1976, not sure about the other one.

Valvemaniac Posted July 28, 2007 Share Posted July 28, 2007 Hi Which part of the shaky isle are you in. (I'm in Auckland) If you need any technical help with the amp or speakers I may be able to assist. Regards, Steve. Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted July 28, 2007 Share Posted July 28, 2007 very pretty- you done good Welcome to the Madness! Michael Quote Link to comment Share on other sites More sharing options...
kkerley33 Posted July 28, 2007 Share Posted July 28, 2007 The serial number listings are above. As I have encounted on a couple of occasions, that 185607 serial number is probably actually 18S607. These speakers were most likely made a couple of years apart but still close enough that they have same crossovers and drivers. Welcome to the fun, you'll be glad you joined. I know I AM.

Islander Posted July 28, 2007 Share Posted July 28, 2007 Sounds like you have a 1976 and a 1978. They're likely pretty well identical. The one in the photo looks sort of shiny for Birch Raw, so I'm guessing maybe they had some sort of treatment done (varnish, lacquer?), but it looks really good. How do they sound? BTW, the serial numbers may be stamped into the top of the back panel, on the edge. Quote Link to comment Share on other sites More sharing options...
Kiwi Boy Posted July 29, 2007 Author Share Posted July 29, 2007 Hi, I am from Christchurch. They have been varnished by the look of it the label on the back has been painted over with something brown. Cheers Nick Quote Link to comment Share on other sites More sharing options...
