MTX 5515-22 15" 800 Watt Peak/400 Watt RMS DVC 2-ohm Car Audio Subwoofer Sub

The MTX 5515-22 is a 15" high-SPL car audio subwoofer from the 55 Series, built for systems where bass output is the priority. It borrows hardware from the MTX 75 and 95 Series SuperWoofers, so it plays hard and loud for long stretches while keeping bass accurate rather than muddy.

Dual 2" 2-ohm voice coils handle 400 W RMS and 800 W peak, matched to a mono amplifier in the 200-400 W RMS range. Dual coils give you wiring options: run them in series or parallel to land on the impedance where your amplifier makes its rated power, or wire a pair of woofers together for a bigger system. Frequency response covers 19Hz - 130Hz at 85.4 dB sensitivity.

Thermal control comes in two layers. Spider Plateau Venting is a mechanical cooling process that targets cool air at the voice coil, and a radial ribbed t-yoke acts as a heat sink to pull temperature out of the motor. That combination keeps the woofer playing at volume instead of compressing after a few songs.

The MTX Inverted Apex surround is narrower than a traditional half roll, which widens the effective cone diameter for 85.43 cu in of volume displacement and higher SPL. A progressive suspension lowers distortion at high excursion. Use a sealed box of 1.5 cu ft or a vented box of 2.48 cu ft, in a trunk, hatch, truck cab, or custom wall build.
