The build quality is decent for a sub that there is no other to compare it to but it slammed for 2 monthe's on 4k and before I owned the guy was running a rf t2000 bd never had no problems with it and it has a really great a sq for a sub that handles 5000 rms It hits lows highs also can hit songs from club music to young jeezy. The reason I'm selling it is I have to many subs I have 2 dd 9900 18s a 2010 t3 tsns 15 and a robot 18 to much laying around.But like different stuff lik amps and other subs that I haven't tried
