Our 10” 4 ohm Marine Passive Bass Tubes are high power handling woofers that are highly efficient thanks to the Bass Tubes enclosure. It’s one of the biggest and baddest Bass Tubes we build, which means it has the power to please all but the hungriest of bass freaks without sacrificing coveted storage space on your boat. They have a 2” high power/high temp voice coil, 10” high power handling woofer and are salt, fog and UV certified. You won’t have to break the bank buying a 1000-watt amplifier as it has more than enough power. Recommended power is any amplifier 100 watts and up. For secure mounting and easy removal, we’ve included weather-resistant, Velcro-reinforced mounting straps, too.
