7515-22 15" Competition Subwoofer Pair, DVC 2-Ohm

The 75 Series SuperWoofer is MTX's competition platform, built for drivers chasing SPL numbers without giving up long-term reliability. This listing is a matched pair of 15" DVC 2-ohm subwoofers, combining for 3000 W peak and 1500 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, a cast aluminum basket cuts resonance, and the glass fiber cone adds stiffness without extra mass. Rated for a 20Hz-140Hz frequency response at 87.53 dB sensitivity, each sub uses a 2.5" (dual) voice coil and needs a 8.375" 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 competition box built for SPL events and dB drag runs. Run them off a single mono amp near their DVC 2-ohm rating and expect clean, controlled bass rather than the loose, boomy output that comes from underpowering a sub this size.
