Had these for a day and they are great little subs. Half price brand new from Velodyne with free shipping. Very powerful sounding even though they are 180 w RMS / 360 dynamic. Terrific for music, has improved overall imaging. Also has setup mic, remote, LFE input, auto on/off. Double boxed serious packaging. If you are in the market for a smaller, musical sub on a budget, this is worth a look.
