These sleek 7.7" speakers offer a mounting profile that tops out at 3/32” (2.5mm), so they'll fit nearly flat and blend right into today's marine design trends. Another plus — Fusion's innovative “speaker legs” keep the speaker in place so you don't have to drill holes in your boat.

Made for life on the water

These Fusion FM Series speakers combine beauty and brawn, with power handling up to 50 watts RMS (200 peak). Designed by people who love both music and boating, these speakers undergo rigorous testing to ensure that they're ready to rock, even in the extremes of a marine environment.

Three-year warranty

They're made to withstand heat, humidity, salt, spray, and high-pressure hose-downs at the dock, so they'll perform for seasons to come. As part of Fusion's True Marine™ line, these Signature Series speakers are even backed by a 3-year warranty.

Available in Black or White

Product Research

Features

True Marine: Fusion describes these speakers as True Marine Accredited, meaning they are designed specifically for the marine environment and backed by Fusion's 3 year warranty. The speakers are tested to ensure they meet or surpass IP65 standards (waterproof and dustproof on the front of the speakers).

Mounting: Unlike most marine speakers, the FM-F77SBs are designed to mount in a square cutout using four rotating cam-locks. The cam-locks rotate into place when you start tightening the mounting screws, then clamp over the ceiling/wall material to securely hold the speaker. The panel the speaker mounts to must be at least ⅛" thick, and less than 1" thick. Each speaker requires a square opening, approximately 6⅜" x 6⅜", and a minimum mounting depth of 3¼". The cams extend just over ¼" beyond the speaker frame.

Compass Safe Distance: The minimum distance the speakers should be mounted from a compass to avoid any interference is listed in the manual. (Approximately 8' from the sides and 9½' from the front and rear of the speakers.)

Speaker Terminals: Each speaker has a seven inch length of speaker wire attached, terminated with male quick slides (0.25" positive and 0.187" negative).

Enclosure: If the speakers are mounted in an enclosure, Fusion recommends 8 liters (0.28 ft³) sealed. An enclosure is not necessary, the speakers will operate in free-air.

Power Handling: Fusion lists two RMS power figures in the manual; RMS Power of 50 watts, and a Recommended Amplifier Power range of 20-150 watts RMS per channel.

Woofer Size: Fusion calls this speaker a 7.7", which is similar to its frame size. However, the diameter of the woofer cone is approximately 4½".
