American Bass Biker Series Speaker 8”

American Bass BK-8 Biker Series 8” Speaker – 400W RMS, 4 ohm

Sold by AudioSellerz.com.

The American Bass BK-8 from the Biker Series is built for bikes and small cabins that need serious midrange output without giving up sound quality. With 400 watts RMS / 800 watts max, a 1.5” voice coil, and 96 dB sensitivity, this 8” driver is tuned to play loud and clear over wind, road, and exhaust noise—perfect for motorcycle fairings, bags, side-by-sides, or high-output door builds.

A carbon-fiber cone and rubber surround add weather resistance and durability, while the wide 70 Hz – 18,000 Hz frequency response lets the BK-8 cover mid-bass through upper midrange in pro-style systems.
