Which Speaker Size is Right for your Boat?

Bolt Hole Circle (B):  7.97 in / 202 mm
Woofer Mounting Hole Diameter:  7.375 in / 187 mm
Woofer Mounting Depth:  5.18 in / 132 mm

Thanks to 36% more cone area and almost double the excursion capability, the M880-CCX's are capable of +6 dB greater low frequency output than our M770-CCX 7.7-inch coaxial systems.

M770 Series
Oversized 7.7-inch Speakers

Woofer Mounting Hole Diameter:  6.25 in / 159 mm
Woofer Mounting Depth:  3.15 in / 80 mm

Oversize design results in more cone area, higher output and better bass response than "6.5-inch" marine speakers. Requires larger mounting hole and mounting flange area.

 

M650 Series
Narrow-Flange 6.5-inch Speakers

M650 Mounting
Woofer Frame Outer Diameter (A):
