Louder, Clearer Audio from Any VHF Radio.
The Standard Horizon MLS410SPB is a weather-resistant external speaker purpose-built for marine VHF radios. Whether your helm station is noisy from wind, engines, or waves, the MLS410SPB delivers up to 10W of clean audio output so you never miss a call on Channel 16. At 5" in diameter with a simple two-wire connection, it installs quickly and works with virtually any VHF radio that has a speaker output — including all current and legacy Standard Horizon models.
Designed for permanent installation, the MLS410SPB can be flush-mounted into a panel or bracket-mounted on a bulkhead or helm surface. The included 6.5' speaker cable gives you flexibility in routing without the need for extensions in most installations.

Parts Desk Insights
The MLS410SPB is the go-to external speaker for boaters upgrading their helm audio or adding a secondary listening station. It's especially well-suited for pairing with fixed-mount VHF radios like the Standard Horizon GX1800GW Explorer, GX1410GPS Eclipse (White), GX1410GPS Eclipse (Black), or the GX2410GPS Matrix AIS+GPS. The two-wire connection makes it a straightforward add-on for any installation, and the flush-mount option keeps the helm looking clean. If you need a power cord for your fixed-mount radio, see the Standard Horizon Power Cord with Inline 6A Fuse.
