Yes and no. I have a Velodyne 15HGS sub that is hidden in the corner to the right (got that baby in a mass buy in '01, still going strong), and picked up a 7 speaker Velodyne satellite-style surround set on clearance for this room (edit: orig installation was in ~2007). It's not amazing, per se (it's no M&K, that's for sure), but the effect in my small-ish room (15'x15'x7.5') along with the LFE from the sub is enveloping.
