Know before you buy
CRGBW lighting includes a dedicated cool white LED chip in addition to the standard red, green, and blue. This allows for a much broader range of color options and a cleaner, more natural white light compared to mixing colors to simulate white.
Yes, these speakers are built with a True-Marine design and include corrosion-resistant hardware. They are specifically engineered to withstand the harsh conditions of saltwater exposure.
CURV cone technology creates a woofer that is both lighter and stronger than traditional materials. This results in better sound definition and higher efficiency, allowing the speakers to produce clearer audio even at higher volumes.
While these speakers do not have a built-in amplifier, they are designed to handle up to 330 watts of peak power. To get the best performance and sound quality, we recommend pairing them with a compatible marine amplifier.
