Introducing the new FUSION RV-FS402B, Black Sound-Panel, a revolutionary new speaker system made for boating enthusiasts and the diverse needs of different vessels. The Sound-Panel solves the age-old problem of delivering professional sound quality from the limitations of shallow mounting depths often required in many installations. The Sound-Panel boasts two soft dome tweeters, two custom 4" speaker drivers and a bass radiator, all perfectly tuned to the Sound-Panel enclosure. Together this delivers 200 Watts of powerful and high quality audio to your vessel. Optional mounting spacer accessories are available to suit the variable mounting depths of every boat.
