"Boasting vibrant lights and thumping audio, the DS18 HYDRO 25"" Marine Sound Bar 6-Speaker System brings the party to your boat! It features four 4"" speakers and two 1"" titanium tweeters to deliver clear and powerful sound across a wide range of frequencies. Left and right input for stereo application ensures balanced and immersive audio, and 94.7dB sensitivity means it will draw less power to be as loud as other comparable speakers with less sensitivity. Built-in RGB LED lighting spruces up your system with a dynamic visual element, while 8 core wires for RGB lighting and speakers let you match the lighting to your mood or setting. Compatible with the DS18 LED-BTC or other RF/BT/Wi-Fi controller for multifunction RGB LED lighting (both not included). IP65 marine-grade construction resists water and dust for reliable use on the boat. This sound bar system also makes a great addition to your car, or other powersports vehicle!
