I went fishing, to see what a good deal was. The guy emailed back & said he is expecting around 800 apiece. The the theater opened up around 1996. Closed recently. I'm suspecting they got round 8hrs of use every day since then. Them places do get loud at times. So Basicly over around 40,000hrs of use (At minimums), around 16yrs in service.
Near the end of the road for these bad boys, or is he a little off base? Believe me this area is vary short on audio nuts (me included), once over the $300 limit, the interest is slim.
Not to mention if your married, try & get these industrial looking beasts in your living room without a fight.
