by dunksalot on 11/22/2016I bought a pair of these after reading many positive reviews. I listen to all kinds of music - hip-hop, reggae, rock, and electronica - so I wanted something to cover the whole gamut.
The first time I fired these up I was in awe. I heard sounds I never heard before in songs/tracks I knew. I had no idea subs could bring such clarity to the overall listening experience (mainly with acoustical music.)
I cannot get any hair tricks out of these and have them powered by a 2000W DC Audio amp. It could be due to the sealed enclosure.
