Sorry about the title I mean to say 350-400..
As for me I was looking at the 350, for somebody that is not to knowledgeable I thought it would enough for me, and I can just set the crossover setting with the Yamaha..
As for placement I had this problem with my last Polk sub was that it was next to my left front tower and never really heard it all that well except when I got up to leave the room all of a sudden there was "sub".
So for this one I was thinking about to the right of my sitting position about 6 feet away in the corner.
Thanks
