BOSS Audio MRWT40RGB 4 in Marine Wake Tower Speakers - RGB

In this review of the BOSS Audio MRWT40RGB wake tower speakers, the bottom line is simple: these compact, weatherproof 4 in full range speakers are for boaters who want clear, roadready sound and striking RGB lighting without a complicated install. The system pairs a 4 in midbass driver with a 25 mm dome tweeter to deliver usable clarity at highway speeds, and the IPX5 rating plus rubber surround and poly injection cone materials make them resilient in marine conditions. If you want a plug-and-play pair with wireless lighting control and solid midrange punch, they are worth considering.

Key Features

• Compact 4 in driver: The 102 mm midbass driver keeps the enclosure small while producing clear midrange that carries well over wind and water noise.
• 2-way design: The included 25 mm dome tweeter adds high frequency detail so vocals and instruments stay intelligible at speed.
• Weatherproof build: IPX5 rating, rubber surrounds and poly injection cones help resist spray, salt and temperature swings for marine use.
• Multicolor RGB illumination: Twenty selectable colors and multiple patterns let users customize tower lighting and control it with the supplied wireless remote.
• Fit and mounting: The speakers are sized to fit bars from 1-1/2 in to 2 in, making them compatible with most wake tower and roll bar installs.
• Power handling: A 400W max power rating and 94 dB sensitivity make them easy to drive with modest amplifiers or a factory system upgrade.

Who It's For

The MRWT40RGB is aimed at recreational boat owners, wakeboarders and anyone who needs compact tower speakers that survive marine conditions and still deliver clear sound at cruising speeds. The wireless RGB control is a plus for those who like to match lighting to evening activities or onboard entertainment.

They are less appropriate for buyers who want deep, roomshaking bass from tower speakers or who need larger drivers for full low end; customers seeking heavy bass should look at larger tower speaker options or add a dedicated marine subwoofer.

Pros & Cons
