The price is right. Someone could easily get $40 worth of value out of that stack. A couple sets for the garage, a pair for the basement, a couple to give away...
$40, what the heck. Those 4 column speakers may have something useful. The rest, $5 per set canon fodder or a giveaway at some school to younger kids who are economically disadvantaged.
The only thing I saw of interest were the Boston Acoustic 5.0? set. They might be useful if you need some small speakers for surrounds for Home Theater or a small semi-portable setup for a cabin. There might even be a small sub for them hidden in the pile.
Those "tower" speakers look suspiciously like they came out of a church. You know, bolted to the faux marble columns so you could hear all the way in the back? Truly, the worst audio reproduction equipment ever conceived.
I know that seller. Owns an electronics salvage shop in downtown Springfield. Gets some pretty neat stuff in and sells fairly cheap. I've made a small fortune off him reselling what I've found in there.
