Good value.

The following review is for HFX12D4BK, which is a part of the bundle you are viewing.

This is a good value. So far, I'm pleased with the performance of these subs. I'll monitor them for durability and bump up to a better-known brand if they fail. I already had a hifionics amplifier, that I have gotten great performance out of for the past several years.
