PowerBass XL-1040T 10" 4-Ohm Shallow Mount Subwoofer The proprietary one piece cone gives accurate and efficient bass to a system without taking a whole lot of space. Designed to work best in a small sealed enclosure that will fit in most spaces that a standard woofer won't opens up new possibilities for the most discerning music fan. Using the same turbine style Poly/Glass Fiber basket as the standard XL subwoofers this shallower version offers all the features and reliability from the Xtreme family. Boasting a flat injection molded cone and inverted ferrite magnet these drivers come in nearly 2-inches shorter than their standard XL counterparts.
