The SSL E12D came sooner than expected. I have to admit. I hesitated when I first felt the weight of the subwoofer. It was very lightweight, but apparently that does not matter anymore with todays technology.From my experience over the years with car audio electronics, sometimes certain brands of subwoofers and speakers have a break in period. The SSL E12D is one of them. It was very tight in the beginning. So I put it through my normal 20 hour breakin period for subwoofers. I must say, it sounds beautiful. The is no distortion from the cone and the bass response is outstanding.Definite buy for me. SoundStorm is a good middle grade brand.
