This 600-watt Pyle Blue Wave subwoofer is a monster! You simply can't settle for anything less than the best when playing back your favorite music. This 12' high-power 4 ohm subwoofer sits in a bandpass enclosure for highly detailed, bumping bass. A 2' aluminum voice coil generates the sound, resonating through the bass reflex vent for added sub-bass response. Plus, this sub doesn't just sound great — it looks great, too, thanks to the plexiglass front window.
