Compromises, we all have to make them. But just because you compromise doesn’t mean you have to settle. The Diamond Audio D6 subwoofers are the perfect example. Whether your listening tastes are as varied as smooth jazz or gangsta rap these woofers will not disappoint you.

Diamond Audio Technologies starts with an industry leading hard-anodized alloy cone that is both extremely rigid and lightweight. They then add an aluminum dust cap to help draw heat away from the voice coil. This improves power handling and reliability. Add in massive motor structures, vented Venturi cooling and large 3” dual voice coils, and you have a subwoofer to be reckoned with.

I called Sonic Electronix's customer service number and they fully answered my questions. I was completely at ease that this was the right product for my car. It was at least $20 cheaper than B*** B** and I received free tracking! This seller's going on my "favorites" list!!
