The Gladen Aerospace-10 Sub 10" 400W RMS 4-Ohm Sound Quality Subwoofer Bass Speaker is a high-quality car subwoofer designed for optimal sound performance. With a powerful 400W RMS output and a single voice coil, this speaker delivers impressive bass response and clarity.
These subwoofers were removed from my competition vehicle and are in good condition. The foam around the cone is because I mounted them inverted (see pic). The $750.00 is for one subwoofer, $1500.00 for both with free shipping.
