Digital Drive (Velodyne DD) series are just fantastic. I run a DD-18, which I upgraded from a DD-12 only because I got one of those 'too good to pass up deals' on it. But the smaller one was too, absolutely amazing. The EQ function works and works well to make the sub compliment mostly any room and system. I've found them to add so much to my speakers it was like I upgraded the speakers too! You must give them a listen in your environment set-up if you can. You'll be convinced.
