The BH-15S500 is for builds where "loud enough" isn't in the vocabulary. The 15-inch cone moves serious air and the dual 2Ω voice coil lets you wire to 1Ω (parallel) or 4Ω (series) depending on your amplifier's sweet spot.
Heavy vented pole piece prevents thermal compression during extended play. This sub is at home in a ported enclosure tuned to 30–35 Hz.
