Bowers & Wilkins Marine 8 Two-Way Marine Speakers

Bring premium Bowers & Wilkins sound to demanding outdoor and marine environments with the Bowers & Wilkins Marine 8. Designed for boats, yachts, pool areas, patios, and other exposed installations, this high-performance two-way marine speaker combines a large 200mm (8-inch) polypropylene bass/midrange driver with a 25mm (1-inch) soft-dome tweeter for powerful bass, clear vocals, and detailed high frequencies. An IP66 rating when properly installed helps protect the speaker against water and harsh environmental conditions, while marine-grade stainless-steel hardware and corrosion-resistant construction deliver long-term durability.

Despite its powerful 8-inch driver, the Marine 8 requires only 93mm (3.7 inches) of mounting depth, making it easier to integrate into space-limited installations. Its wide 36Hz to 26kHz frequency range provides deep, weighty low-frequency performance alongside crisp high-frequency detail, while an 8-ohm nominal impedance and recommended 20W to 80W amplifier power range make it compatible with a variety of high-quality marine and distributed-audio systems. For installations that demand both rugged construction and refined sound, the Marine 8 delivers Bowers & Wilkins audio performance in a purpose-built marine design.
