KICKER TB8 8-Inch Loaded Weather-Proof Subwoofer Enclosure – 4-Ohm, 300W

Powerful, compact, weather ready audio

The TB8 packs a serious low end into a compact, weather proof enclosure. On one end you find an active CompR woofer with a ceramic magnet and advanced suspension. On the opposite side sits a Reflex passive radiator that works with the active driver to extend bass depth without taking up extra space.

Its rugged thick ABS shell stands up to sun, rain, dust, and vibrations, making it a versatile partner for outdoor adventures. The enclosure is designed to endure long days on the road, trail, or water while delivering consistent output when fed by a capable amplifier. The 4 ohm impedance and a 300 watt rating offer a solid path to strong performance with compatible gear.
