Finding an affordable yet high-performing subwoofer isn't an easy task, but the Pioneer TS-W1007D4 is exactly that. It's not everyday that anyone could get a cheap subwoofer that is also powerful and reliable; so read carefully because this may very well be one of the best deals available to you.

The subwoofer features the now commonly used injection molded polypropylene cone woofer. However, it is not just plain polypropylene but is compounded with interlaced aramid fiber or also known as Kevlar. The material utilized along with its woven fiber radial surround creates an extremely tough and rigid construction, allowing for greater bass response while maintaining consistent performance in any environment.

The Pioneer TS-W1007D4 is primarily regarded as an entry-level subwoofer. However, it packs a big punch for those who do not want to spend much money on their car audio equipment. Its 10" cone woofer is capable of delivering up to 1000 watts maximum power and could consistently produce 350 watts of CEA rated RMS power out of dual 2 ohm ( TS-W1007D2) or 4 ohm (TS-W1007D4) 4-layer copper voice coils. Don't overlook its hefty 74oz. dual-stacked magnet structure that when combined with the mentioned specs could produce that boomy bass you've always wanted.
Another great feature of the TS-W1007D4 is its ability to pick up frequencies as low as 18 Hz to as high as 600 Hz. This means that this 10" subwoofer could produce sound frequencies just below what you would typically call "midrange". When combined with a decent component speaker system, the results would be great audio reproduction in your vehicle.
Cosmetically, this subwoofer looks good. It has a classy look, not overbearing, but is still able to give off an intimidatingly powerful image. The basket is a stamped design with all four terminals on one side for easier installation. An additional but optional grille is available, allowing the cone to be protected and cosmetically enhanced.
