That Aperion sub is nice looking, no way around it but it only goes down to 35 hz and weighs 27 lbs, the Velodyne goes down to 28hz, weighs 53 lbs, is well over $100 cheaper even though it usually retails for $100 more and it has a remote. No more getting up and you can tune in the sub from your couch. I'd go with the Velodyne in this case. I think you could get better bass for $500 but not $270 delivered.
