Soundstream X5.15 15-Inch Dual 2-Ohm High-Excursion, 3,500 Watts RMS Competition Car Subwoofer
The Soundstream X5.15 is a high-excursion 15-inch car audio subwoofer built for bass enthusiasts and SPL competitors who demand relentless low-frequency output. Designed to handle intense power and thermal stress, the X5 series combines heavy-duty voice coil engineering with high-density magnetic structures to deliver deep, chest-thumping bass response. Whether installed in custom ported or sealed enclosures, the X5.15 delivers exceptional linear excursion and low distortion under high-stress listening conditions.
Featuring a rugged non-pressed paper cone, high-roll foam surround, and heavy-duty dual-layer spider suspension, the X5.15 ensures mechanical stability during extreme excursion. Its high-temperature voice coil design and vented motor structure maintain cool operating temperatures during prolonged high-volume playback. Constructed on a cast aluminum frame, the Soundstream X5.15 provides the structural rigidity and electrical performance necessary for serious vehicle audio builds.
