Integrating a sub into a two channel system is difficult, but does not have to be. I use a Velodyne SMS-1 equalizer with my system and have great success playing all types of music. I do not have bass boom, droning, or one bass notes that some people are experiencing. It takes a lot of time and effort to get the correct volume, phase, and EQ set properly to listen without having to adjust any settings. Regarding having enough bass, someone is asking for a sub to go with a pair of Wilson Audio Maxx III's in anoher forum. Once you do have a sub setup properly, you can always turn up the bass volume for parties, jamming out, and other reasons to play loud.
