How many speakers come in the box?

The MR50 Series is sold as a matched pair, so one purchase gets you two 5.25 inch marine speakers in the same color.

What colors are available and how do I choose?

The MR50 comes in Black (MR50B) or White (MR50W). Both have identical specs and mounting dimensions, so pick whichever finish matches your boat's hull, dash, or cabin trim.

What size mounting hole do these speakers need?

Each MR50 speaker requires a 4.94 inch mounting hole and a mounting depth of 2.2 inches, matching standard 5.25 inch speaker cutouts.

Are these speakers actually waterproof?

The MR50 is weatherproofed to resist moisture, spray, and humidity typical of a boat or outdoor vehicle, using a treated cloth surround and weather-resistant materials throughout the driver.

What is the power handling of the MR50?

The MR50 pair is rated for 150 watts total, with a 4 ohm impedance per speaker.

What is the frequency response and sensitivity of the MR50?

Frequency response runs from 80 Hz to 20 kHz, with a sensitivity of 89 dB at 1 watt/1 meter, covering the full audible range from a single 2-way driver.

What materials are the MR50 speakers made from?

The MR50 uses a polypropylene cone, a 1 inch Mylar dome tweeter, a treated cloth surround, and a plastic basket for corrosion resistance.

Will Black and White versions sound different?

No, both colors share identical drivers, power handling, frequency response, and sensitivity. Color is purely a cosmetic choice.

Can these be used outside of boats?

Yes, the weatherproof design also suits ATVs, UTVs, motorcycles, patios, and other outdoor installations exposed to the elements.
