Sundown Horizon 8" 500 Watt RMS Dual 4 Ohm Car Audio Subwoofer HZ-8

This Listing Includes:

• (1) Sundown Horizon Series HZ-8 Dual 4 Ohm Subwoofer

The HZ-8 from Sundown Audio is built to deliver serious bass from a compact footprint. Rated at 500 watts RMS with a high-temperature 2 inch voice coil and class-leading 14mm Xmax, this subwoofer is designed to move air efficiently while staying controlled and musical.

A heavy-duty cast aluminum basket, stitched tinsel leads, and bolted spider pack give it the strength to handle daily power with ease. The high-roll surround and progressive spider provide smooth excursion, while the vented motor gap and pole piece keep temperatures in check during hard play.

Perfect for small builds that still want real output, the HZ-8 shines in ported enclosures and delivers tight, punchy bass that feels much bigger than its size.
