Paradigm vs. Velodyne

paradigm is a good sub,but velodyne is a great sub.the 15's would be faster,but the 18 has more presence.i prefer the older velodyne uld-15 for every application[especially music]with a separate amp and servo control it dominates in my opinion.i have 2 of these in a 22x26 room and when a low cycle wave[17hz] hits you, your stomach is like jello. they don't make these anymore,but always see them on the net 500.00-800.00 for the uld-15 series 11-the 18 is good but not nearly as fast.a good test is the movie the professional in the beginning[in the hotel scene]there's a 16 cycle wave that'll make an ass out of most subs but the velodyne12's and 15's[most others will start ratteling]good luck
