The P12SW performs like a pro, with technology developed by JBL’s Professional division. Equipped with JBL's tried-and-true PolyPlas woofer, this subwoofer delivers the low-frequency goods. Special effects in your favorite movies, assisted by the FreeFlow flared port, are loud and clear, without unwanted distortion or boominess. An efficient digital amplifier backs up the 12-inch woofer with high output. Sturdy gold-plated, 5-way binding posts provide a strong connection that preserves all of the nuances of the original program.
