I've had this set of speakers for years (http://usa.yamaha.com/products/audio-visual/speaker-systems/speaker-packages/ns-p220/?mode=model#list=within&mode=paging&page=5) and they're honestly ok most of the time. The sub as you can imagine is pretty weak at 50W (not sure if that is peak or RMS, my guess peak) and only 6.5". Finding a spot where that sub did anything at all was a small challenge of its own.
For a 18'x12' room what would be a more appropriate size sub? This is how the room looks - http://cl.ly/M1IV
