(4) RWB70B Black 6.5" Marine Wakeboard Swivel Tower Speakers + Receiver

This kit pairs four RWB70B 6.5" black wakeboard tower speakers with an RGHR2 gauge-hole Bluetooth receiver, giving you a source and speakers in one package. The RGHR2 fits a standard tachometer cutout and includes a built-in amplifier rated at 28W x 4 RMS, enough to drive all four speakers at moderate volume right out of the box. For louder setups, two sets of RCA preamp outputs let you add an external amplifier later. Bluetooth streaming reaches up to 50 feet, and there are USB, auxiliary, and AM/FM inputs for additional source options. An included wired remote on a 32.8 ft cable lets you control everything from the helm or the stern.

Each RWB70B handles 150W RMS through a polypropylene mica-injected cone and 1" neodymium tweeter with a built-in two-way crossover. The 360-degree swivel brackets rotate and lock so you can aim sound toward riders behind the boat or passengers at the helm. Nylon brackets reinforced with embedded steel clamp bars from 1.26" to 2.87" and include dual-length stainless steel screws. Every speaker component is marinized against salt and fresh water with sealed terminals and a waterproof coating.
