The 4-ohm, single voice coil subs are internally wired in parallel to present a 2-ohm load. Each subwoofer features a StampCast steel frame, a Kevlar fiber reinforced paper cone, and NBR surround (Nitrile Butadiene Rubber). Anodized aluminum voice coil formers and spider venting help keep the subwoofers cool. Spider: A compliant linear spider made from tear and fatigue resistant poly-cotton improves mechanical stability under high excursion, maintaining consistent excursion characteristics. Solid MDF Construction: The enclosure is constructed of high quality 5/8" MDF (medium-density fiberboard), which resists flexing and has anti-resonant qualities. Vented Enclosure: The vented enclosure is aided by precision construction through computer design. The enclosure consists of two front firing 12" Punch P1 series subwoofers with a proprietary high-flow, low-noise port. The speaker terminals are located on the left side of the box (when facing the box). The box is covered in black carpet. Tuned Port: The enclosure uses a front-firing proprietary high-flow, low-noise port to help produce deep and loud bass efficiently. Box Carpeting: The enclosure is finished with high-density carpeting for superior durability. The carpet is black. Speaker Terminal: The subwoofer enclosure uses one pair of high current, spring loaded binding posts. The binding posts are located on the left side of the box and will accept pin connectors, single or dual banana plugs, or bare wire up to 10 gauge. Power Handling: The subwoofer can handle up to 500 watts RMS; 1000 watts peak power. CEA-2031 Compliant: Power handling on the P1S4-12 subwoofers conforms to CEA-2031 industry standards. This means the subwoofer has the capacity to handle its rated power under continuous demand, not just for an instant. Dimensions: The depth dimensions listed in Features & Specs include the subwoofer's trim ring, which adds approximately 7/8 of an inch. The depth of just the enclosure is 15-3/4 inches at the base and 13 inches at the top.
