5515-44 15" Car Subwoofer Pair, DVC 4-Ohm

The 55 Series is MTX's high-SPL platform, tuned to move air and deliver bass that carries well past the driveway. This listing is a matched pair of 15" DVC 4-ohm subwoofers, combining for 1600 W peak and 800 W RMS so a single mono amplifier can power both from one channel. The Inverted Apex surround adds cone surface area for more air movement and higher SPL, while the progressive suspension controls excursion at high power to keep distortion down. Spider Plateau Venting and a radial ribbed t-yoke pull heat off the voice coil so output holds up over long sessions. Rated for a 19Hz-130Hz frequency response at 85.4 dB sensitivity, each sub uses a 2" (dual) voice coil and needs a 8.0" mounting depth with a 13.875" cutout, fitting 1.5 cu ft per sub in a sealed box or 2.48 cu ft per sub vented. That makes the pair a straightforward fit for a dedicated enclosure in an SUV or full-size truck built around serious low-end output. Run them off a single mono amp near their DVC 4-ohm rating and expect clean, controlled bass rather than the loose, boomy output that comes from underpowering a sub this size.
