Waterproof three-way marine speaker pair handles 280 W peak power with a 55 Hz–20 kHz frequency response and flush-mount design
- Weight6.1
- Handles 280 W peak power for loud, clear audio
- Frequency response from 55 Hz to 20 KHz covers full range
- Low magnetic field design avoids compass interference on board

- Flush-mount cutout 225 mm x 126 mm fits standard panel openings
Pair of marine speakers for open-cockpit boats
The MA5500 is a flush-mount 3-way platinum panel speaker set sold as a pair. Each unit weighs 2.30 lbs and fits a cutout of 225mm by 126mm with a mounting depth of 39mm. A powder-coated stainless steel grill and colourfast plastic frame resist UV and water ingress for permanent exterior installation.
Suits owners replacing slim-line panels who need
The low-magnetic design allows placement near compasses without deviation. Builders who require a smaller footprint or a different grill colour should look elsewhere because the outside grill measures 255mm by 159mm and only white is available. Installations needing surface mounting rather than flush mounting are not compatible with this frame.
Handles 280W peak per pair with 85dB SPL
Frequency response spans 55Hz to 20KHz through a dual woofer, midrange and mylar tweeter array at 4 ohm impedance. The combination delivers clear midrange and extended highs for open-water listening. Systems demanding deeper bass extension below 55Hz or higher sensitivity for low-power amplifiers will find the limits of this design.

Questions about this item
What amplifier power rating and impedance are required to drive the MA5500 speakers?
The MA5500 handles up to 280W per pair with a 4 ohm impedance. Your marine amplifier must be stable at 4 ohms and deliver sufficient power within that peak rating for clean output.
Will the MA5500 fit the existing cutout from my old Slim Line speakers?
The MA5500 is designed as an upgrade for Slim Line speakers. It requires a cutout of 8-7/8 x 5 inches (225mm x 126mm) and a mounting depth of 1-9/16 inches (39mm). Verify your current opening matches these dimensions.
How can I confirm the MA5500 speakers are performing correctly after installation?
Play audio across the frequency range. The 3-way design with mylar tweeter and midrange should reproduce 55Hz to 20KHz clearly. Listen for balanced output from both speakers at 85dB SPL without distortion at moderate volumes.
