Hear every word loud and clear with an active, amplified speaker kit for your Ray 90 or 91 VHF radio. This speaker kit is ideal for high-noise areas like open powerboats, express cruisers, windy flybridges, or even below-decks on loud vessels. The active speaker contains its own on-board audio amplifier and audiophile-grade speaker. Even at its highest volume setting it delivers crystal-clear audio that you\\u2019ll be able to hear and understand. The speaker is enclosed in a compact housing that is both rugged and waterproof. Mount it vertically or horizontally in any bulkhead or overhead. The speaker connects directly into the nearest wired or wireless handset base.
