RGHR2 + RMC65LB

This hot tub audio system pairs the RGHR2 Bluetooth gauge hole receiver with one pair of RMC65LB 6.5" black marine speakers featuring a multi-color LED lighting system with remote control. It turns your spa, hot tub, or outdoor area into a combination sound and light setup controlled from a single package. The RGHR2 receiver fits a standard tachometer opening and delivers 28W x 4 RMS. Bluetooth streaming reaches 50 feet, USB and auxiliary inputs are available, and AM/FM radio is built in. IP66 waterproof certification handles steam and splash, and the included wired remote on 32.8 feet of cable keeps controls within reach while you soak.

The RMC65LB speakers handle 75W RMS each (600W system peak) with a 55 Hz to 20 kHz frequency response and 91 dB sensitivity. The multi-color LED system offers 20 static colors, 19 dynamic modes, adjustable strobe speed, and five brightness levels, all managed through an included slim card-type remote that can be paired with one or more speaker sets. Polypropylene mica injected cones, rubber surrounds, and stainless steel terminals are fully marinized against salt and fresh water. A 5.31" cutout diameter and 2.48" mounting depth make them easy to install in hot tub cabinets, deck enclosures, or outdoor walls. Included speaker wire, mounting screws, and the LED remote round out the kit.
