Active Subwoofer with in-built 4 Channel Amplifier

Introducing high-end audio for the marine cabin environment with the MS-AB206 Active Subwoofer. Designed for exceptional sound in any vessel, the Signature Series represents the highest quality purpose-built marine audio equipment from Fusion. 

With unrivalled bass reproduction, the MS-AB206 creates the perfect atmosphere for entertaining or relaxing. Specifically tuned to produce the best acoustic result when installed in a saloon or cabin environment, and when paired with the MS-BX3020 cabin speakers, the remarkable sound quality is like nothing you’ve heard before.

The MS-AB206 features a 6" dual voice coil down-firing woofer which is acoustically coupled to a matching passive radiator, producing exceptional bass reproduction. The passive radiator is used to tune the volume and driver for better low frequency performance, eliminating port turbulence and reducing motion compression.
