I bought this sub because it was more non-mainstream than the big names like Alpine, MTX, Kicker, etc. Ive had 2 Type-R 10s, a Kicker L7 15, and many other subs and this little guy beats them all. If you put it in the right size box with a large amount of port area (22mm of xmax moves a lot of air) and feed it the recommended 800-1000 watts rms, then this sub will surprise you. I had limited space in my mustang, and this in a 1.4 ft^3 box tuned @ 35 hz is enough to take your breath away. People cant believe its only one 10" sub!

I bought one of these as a temporary sub to take advantage of an unused sub box that I had built for an old sub. It was a vented box, I cannot recall the tuning but the volume was slightly larger than the max recommended for this sub. Overall this is a solid 10". I believe it has a very good balance between SQL and SPL in the sense that it is very accurate over a wide frequency range and it gets pretty darned loud for a 10". I was giving this sub 1400w rms (brutus 2100 @ 2ohms) and it handled it, though I will say that it lost some of its accuracy near the max volume. I would estimate that 1200w is more reasonable.

Bottom line: this is a well balanced sub that sounds good and plays loud and I believe it is a good value purchase.
