Numerous threads around on these....powered active bi-amped 280 watt speaker. I've used this thing for a long time, and it is about the best thing out there for a clean sound in a small speaker.
In good shape sound wise, has some wear on the carpet, and my name is written on the back in silver marker...easily remedied if you are so inclined. I've owned 2 and kept this around, but it just doesn't see the light of day anymore as I provide the PA for the band with my Bose PAS and I would rather have the money now.
http://www.lnrmusic.com/PUB2-280.html will tell you all about it.
$475 shipped in the CONUS.
As a bonus, I will throw in the Schertler Speaker pole, which I believe is no longer made. Get it up off the floor and ear level....very high quality.
