Subject says it all. I have a pair of SDA speakers in my basement (purchased new in the late 80's). I think they are SDA 1b's but am not sure. Is there a way that I can tell from looking at something on the speaker? (SDA cable is the double blade type, not blade/pin if that helps.)
Also, I have read in a few places that there is a tweeter upgrade available for these speakers. Is that true and what is the difference between the factory tweeter that I have and the new one.
Final question. Would they mate ok with the LSiC that I have now, or should I just run phantom center (they are SDA's after all) and run the 7's rears with the LSiC as a rear center for 6 channel sound?
