Active External VHF Speaker - White The BAR-VA-1W (White) and BAR-VA-1B (Black) Active VHF extension speakers provide the loudest and clearest amplification of your VHF radio. A built-in 10W DSP amplifier actively removes sound that falls outside of the human vocal range to help you hear those vital communications. Each unit is adaptable to three mounting configurations – switching between Helm and Overhead Mount is achieved by just rotating the included mounting bracket – or removing the bracket altogether for super sleek flush mounting.
