• (1) Horizon Series HZ-10 Dual 4 Ohm Subwoofer

The HZ-10 from Sundown Audio is built for serious low-end performance in compact and mid-size enclosures. Rated at 750 watts RMS with a high-temperature 2.5 inch copper voice coil and a class-leading 14mm of excursion, this subwoofer delivers deep, controlled bass with impressive efficiency.
