\rLow profile subwoofers are typically not quite as good as their full-size counter parts, but there are some exceptions to the rule. It used to be that thin-woofers sounded thin. The engineers have since found ways to make them significantly better so that\ryou get full sized output from a low-profile subwoofer, but in general, the full size version will just sound better, all other things being equal. Some of the low-profile subwoofers that we really like include the JL Audio TW3, Kicker Comp RT, Kicker L7T, Rockford Fosgate T1S, Rockford Fosgate R2S, and the Kenwood eXcelon 10" low profile. Most of the other shallow\rsubwoofers sound shallow. We recommend the models we just listed if you are tight on space.\r
