Performance and Installation

The separate high-frequency driver and woofer work through the coaxial crossover for balanced sound in open-air listening areas such as cockpits and decks.

The Sport grille incorporates the visible design detail, while separate RGB wiring permits the illumination to be controlled independently from the audio signal.

Mount the speakers on a stable panel with adequate rear clearance; use appropriate marine-grade wiring and protect speaker and illumination connections from moisture.

A suitably rated amplifier can help maintain clarity over engine, water and wind noise. Power recommendations apply to each speaker rather than to the pair combined.
