It hits higher end bass ok at best and descent low low end for a 10" but there is not a punch like a 10" should have. The actual SD (Look it up. It's the cone Surface Area in cm or inches. MORE SD IS BETTER FOR BASS ADDICTS) is so low that it would take a wall of these to be anything awesome. Look into an Alpine SWR or SWS 10" subwoofer if you have looked at this.. honestly... I keep mine around for when we are testing connections or like when we I blew my 12"SWS or to diagnose an issue.... I experimented when I bought this and failed. I graduated to an Alpine SWR12D2 eventually and now I'm getting what I really wanted to hear. For REASONABLE PRICES look elsewhere on amazon or something for some real quality subs, not KOLE owned by Power Acoustic that is a discontinued project. Check out Alpine sws and swr 10" and 12" subs. I love my SWR @1ohm, all day booms. So will you. Promise.
