The new fourth-generation Type-S subwoofers have undergone a revolutionary redesign, leaning heavily on patented technologies developed for the Type-R series. The result is a subwoofer that is so good we had to redesign the Type-R. These new subwoofers redefine the expectations in their class. Altogether, they offer significantly improved output, deeper bass extension, more control and even greater power handling.

|For the money paid it's worth it. Overall performance is just ok. It will leave you feeling for a tad bit more bass, punch, etc. Lows are not that good, rolls suck. If your short on cash, its a good buy. If money is not an issue the type R is a better bet.|
