Add a passive speaker to your wired handset station for crystal-clear audio from your VHF system. Raymarine’s passive speaker kit is ideal for lower-noise areas like pilot houses, salons, staterooms and navigation tables. The unamplified speaker is housed in a compact enclosure that is both rugged and waterproof. The speaker can be mounted horizontally or vertically in any bulkhead or overhead and plugs directly into the wired handset base.
