Earthquake Sound DB-15 Car Subwoofer

Pros: Price, Depth, Pace, Power handling, Build quality
Cons: For the price - there aren't any

I bought this sub and stuck it in a ported box. It sounded quite bad at first, but that was because the box was the wrong size and port length (Tuned for 60Hz) I have since had it in a sealed box and a ported box tuned down to 22Hz (Although that was quite big) The recommended ported boxes were not optimal (IMO). It gives good bass response (The bass you expect from a 15"!!!) and is certainly better than most other subs in this price bracket. I wouldn't hesitate to recommend it to someone who is starting out and wants to hit the basement! However, pros should look into a BALLS 15 or 18" or at the very lease a DBXtreme. Nevertheless this offering was my entry into car audio and it met my expectations for offering lots of boom for a little bit of the green stuff!
