Does anyone own one of these yamaha subs or have any info on them other than general specs that I've found online? I have the oportunity to purchase one of these used to use as a second sub in a large room for around $200 with 4 yamaha sattelite speakers with stands and a yamaha center channel. The seller wants to sell everything as a package deal, though I have no use for the other speakers I really need another sub. So my question is this yamaha sub worth the 200 I would have to pay to get it as a package deal. If it would compliment my current system and is worth around 150 itself I think ill jump on this deal and maybe use the other speakers in a small bedroom or something. What are your thoughts?
