3512-04S 12" Shallow-Mount Subwoofer Pair, SVC 4-Ohm

MTX's shallow-mount 35 Series packs the same cooling and surround technology as the standard lineup into a body shallow enough for tight cavities. This listing is a matched pair of 12" SVC 4-ohm subwoofers, combining for 1200 W peak and 600 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 channels cool air straight at the voice coil, so thermal buildup doesn't cut a session short. Rated for a 23Hz-130Hz frequency response at 84.4 dB sensitivity, each sub uses a 2" (single) voice coil and needs a 3.375" mounting depth with a 11.125" cutout, fitting 0.8 cu ft per sub in a sealed box. That makes the pair a straightforward fit for a shallow enclosure where cabin space is limited but 12-inch output is still the goal. Run them off a single mono amp near their SVC 4-ohm rating and expect clean, controlled bass rather than the loose, boomy output that comes from underpowering a sub this size.
