I remember going over to put my ear next to the Vandersteen 2wqs to see if they were on, they were, but you could hardly tell, only when taking them out of the system did you notice what they did for bass. The Vandersteen subs with the 3A or 2C blend seemlessly. Great bass should be like that, you don't notice it till its gone. But that is a sub/tower combination designed as a single speaker system.
