The Pyle Audio PLSQ10D are a pair of 10” square DVC subwoofers built from a special-treated silver Polypropylene cone. The first woofer in the Red Label series, the 1200w PLSQ10D is in fact the only 10” square subwoofer offered by Pyle Audio, and competes with the circular-framed 1400w PLCHW10, not to mention the less formidable 1000w PL1090, PLBW104, and pentagon-shaped PLPNW10.
