Summary: I recently had to purchase these r2 subs after switching vehicles and my p3 rocksford's wouldn't fit under my seat , and I was a little doubtful that they would sound anything like my p3's but once I hooked them up and played a bass test cd I made all that doubt went away.
Pros: Will fit in a small box and sound great if u have the correct air space and they are wired right.
Summary: Since my last two subs finally blew I needed some great subs. I bought the low profile ones due to having to put them in the box that fits under my chevy's back seats. Was worried if they would have the sound I wanted and man do they ever!
Summary: I was concerned this subwoofer wouldn't sound as good because it is the shallow design. I was wrong. I built a downward facing sealed box that was only 6" deep so it could sit under my back seat. It sounds absolutely awesome.
Pros: Awesome sound. Thin size, so it fits under/behind seats.
