Small enclosure, impressive bass When space inside your vehicle is limited, it can be difficult to find room for a subwoofer. MTX has solved this problem by creating a shallow-mount powered sub that fits in cramped confines to give you impressive bass without taking up a whole lot of space. So easy to fit MTX designed their TN8MS powered subwoofer to deliver high-quality bass response in an enclosure small enough to fit your vehicle's nooks and crannies. At only 3" high, this sub will fit under most seats and behind many truck seats. With a built-in amp that delivers 135 watts RMS to the low-profile 8" sub, you'll get the rich, full bass you need in a simple, easy-to-fit package. Tune it to your tastes You'll also get a full control set to tune your low end to your music and your tastes. A variable low-pass crossover lets you set the frequency anywhere from 50 Hz to 150 Hz so you can adjust the sound to best complement your speakers. The bass boost control gives you up to 12 dB of boost at 45 Hz, and the phase switch allows additional adjustment to dial in your system. A wired remote control connects to the sub via a 3.5mm cable, letting you adjust the bass response from the driver's seat. Secure and connected The TN8MS features speaker-level and line-level inputs so you can run the sub directly from your car stereo, or get a signal from your speaker wiring. The high-density aluminum enclosure keeps the sub and amp safe from thumps and bumps, and the metal grille protects the speaker. When you need lots of boom but only have a little room, the TN8MS gives you the sound you want in a compact package with easy installation and great sound.
