Randy,
The den is 14x18x8 but it opens up straight into the breakfast nook and kitchen so there is a lot of open space. Probably if I had a back wall, the 10 would work fine but with the open area I think it loses some punch. Yes the PB10 did great in the room. However , I wanted more shake, rattle and roll. I guess bottom line, it boils down to upgradeitis!!!
