The Pyle PLTA8N is a blue wave subwoofer that pushes 250 W of booming bass. The 8" high-power amplified subwoofer tube has a built-in high output amplifier. It's equipped with a silver electroplated polypropylene cone and specially treated black rubber edge suspension for a distortion-free sound that rocks. The 1.5" aluminum voice coil provides the punch, while the bass reflex vent adds even more sub-bass. High quality vinyl wrapped construction keeps your system safe. And these don't just sound great - they look great too, thanks to the blue LED light behind the grill.
