S6510-44 10" Square Subwoofer Pair, DVC 4-Ohm

The S65 Series swaps the usual round basket for a square one, picking up extra cone area and Xmax in the same mounting footprint. This listing is a matched pair of 10" Square DVC 4-ohm subwoofers, combining for 2000 W peak and 1000 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 26Hz-130Hz frequency response at 84.5 dB sensitivity, each sub uses a 2" voice coil and needs a 6.625" mounting depth with a 9.313" cutout. That makes the pair a straightforward fit for a compact sealed or vented box in a hatchback, sedan, or crew-cab truck where trunk space is tight. Run them off a single mono amp near their Square DVC 4-ohm rating and expect clean, controlled bass rather than the loose, boomy output that comes from underpowering a sub this size.
