I'm being offer this sub for $1,300 and would appreciate any comments. What do you think of this price, but more important, I would welcome any opinions on this sub. My application is 60% music, 40% HT. My preference is for clean sound, but I do enjoy the full HT experience. I think I have a pretty good "musical" system that cost me an arm & a leg... B&K AVR507 receiver with Sonus Faber Concertos / center and wall surrounds. I'm running out of $$$ so the prospect of saving money with a used, but compatible sub, is appealing. Any and all suggestions would be appreciated.
