Summary: Used this for a small footwell enclosure in my NSX. With 150wrms it plays nicely, gets lower than I'd expect, and can hang with some of the more bass heavy songs I listen to. For rock it's great; accurate and punchy. Slim profile is nice..
Very inefficient - low sound output without a large amp or high gains.

Summary: When comparing this subwoofer to other shallow small box models on frequency curve software, it reaches nearly a half active lower for the f3. That is why I selected this one. However, in reality, this sub is so inefficient that the gains need to be adjusted greatly to equal any appreciable sound...
Conclusion: I bought this on recommendation from Ford Explorer forums as a replacement for the factory subwoofer. This drops tight in and works and sounds perfect. Good price, quick shipping. Recommended.
Summary: Very very very pleased!!!.., replaced stock sub in 02 Suburban but had to roto zip the box a little to get it to fit. Very easy mod and the sound is superb without needing to take away space with a box or anything taking away from the spacious room a suburban offers
