Description

The PowerBass PS-WB121 is a single 12-inch vented loaded enclosure engineered to deliver deep, tight bass for your car audio system. Its bass reflex design utilizes a computer-optimized acoustic chamber and a slot port system, tuned to a low frequency for powerful sound. The enclosure houses a 12" subwoofer with a 2-layer DDC coated black ribbed paper cone, a 2" BASV high-temperature voice coil, and a double-pressed treated foam surround, all finished in a durable 2-tone aircraft-grade vinyl. This loaded enclosure is built for robust performance, handling 275 watts RMS and peaking at 550 watts. It features a single 4-ohm input, a sensitivity of 98 dB, and a frequency response ranging from 30 Hz to 120 Hz, ensuring it can reproduce a wide spectrum of low frequencies effectively. The dimensions of the enclosure are 18.75 inches in width, 13.5 inches in height, with a top depth of 12.25 inches and a bottom depth of 14.4 inches. PowerBass designed this enclosure with a focus on performance and value, aiming to provide a significant bass upgrade without a prohibitive cost. The vented "bass reflex" enclosure with its slotted port is specifically tuned for loud bass output.
