The Pyle Audio PLW10BL are a pair of 10” subwoofers built from a blue CD wave electro-plated cone. The first woofer in the Blue Label series, the 600w PLW10BL competes with the much more powerful 1000w PLPNW10, 1200w PLSQ10D, and 1400w PLCHW10, but trumps them all with a far reduced price of $36.00 (versus $98.40, $97.50, and $90.00).
