The more I think about the many folks here saying a sub really helps the bass for music even with the Towers is the issue could be two fold: First the obvious, the room acoustics may be lacking. Like I see many pics here with towers laying right there on tile floors, I mean how could anyone hope to achieve good sound on surfaces like that. But what also might be a huge factor in that bass evaluation of the Towers is the fact that I listen to my music on analog VINYL only while most here do so on digital CD or whatever digital feed is available nowadays. And that is a HUGE difference in sound overall, nothing digital will have the depth of analog. There is also a warmth to the sound which is significant in the bass department. Instead digital is cold, just like the tiles Plus of course what's your amp quality like? And are you using 10 gauge speaker wires? All those things will add up in overall bass reproduction. All that to say with my setup the Towers by themselves are king for bass and if they are not for some, it's most likely not because of the Towers. Hope that helps.
