Description

The Fusion MS-OS420 is a pair of 4 inch, two-way marine and outdoor box speakers designed for boats and other locations where flush-mount speakers are not practical. Each sealed enclosure combines a polypropylene woofer with an NBR surround and a PEI cone tweeter to deliver clear, full-range sound, and the compact box format lets you add audio to alloy hulls, transoms, hardtops, garden and patio spaces with minimal fabrication.

\n

Every speaker ships with an adjustable mounting bracket and all the fixings needed, so the angle can be set toward the listening area for the best stereo image. The rugged UV-stabilised plastic housing and corrosion-resistant stainless steel hardware are built to shrug off sun, rain and salt spray, making the MS-OS420 a hard-wearing, value option for a marine or outdoor system.

\n

Rated at 100 watts maximum power with a nominal 4 ohm impedance, the MS-OS420 is an easy match for most marine head units and compact amplifiers. Its solid construction and honest performance make it a popular choice where a discreet, weatherproof box speaker is required.

Are the MS-OS420 speakers suitable for a boat?
Yes. They are sealed marine and outdoor box speakers with a UV-stabilised housing and corrosion-resistant stainless steel fixings, designed to withstand sun, rain and salt spray. The box format is ideal for alloy hulls and other locations where flush-mount speakers cannot be fitted.
What amplifier or head unit do I need?
The MS-OS420 has a nominal 4 ohm impedance and a 25 W RMS (100 W peak) rating, so it works with most marine stereos and compact amplifiers. Match the amplifier output to the speaker power rating for the best results.
How are they mounted?
Each speaker includes an adjustable mounting bracket and all the fixings required. The bracket is fixed to a flat surface and the speaker angle is then set toward the listening area before tightening.
