I have not heard either of these subs, but if those were my only two choices I'd pick the Velodyne. Mind you this is simply based on the fact I owned one 10ish years ago that I thought was really good. I was about 15 at the time though, so if you take my advice its kind of like you went back in time and took the advice of my 15 year old self. Or not at all like that, I'm not sure. I'm very tired.
