The GME GS500 is a pair of 110W IP54 flush mount marine speakers in white, delivering outstanding audio quality in demanding marine environments. At 163mm diameter, the GS500 suits standard round speaker cutouts and provides significantly more power than the compact GS320W box speakers 110W per speaker for powerful, clear audio on larger vessels.
Flush mount installation seats the speaker directly into a cut panel with the grille flush to the surface a clean, professional installation typical of helm areas, cabin bulkheads, and cockpit panels. IP54 protection guards against dust and water spray, with ASTM B117-03 salt spray and ASTM G154 UV compliance confirmed for marine conditions.
Optional black speaker grilles are available separately as the S5BG for vessels with dark colour schemes.

A flush mount speaker is designed to be installed in a round hole cut into a panel — the speaker basket sits inside the panel thickness and the grille sits flush with the surface. This provides a clean, built-in appearance compared to a box-style speaker that mounts on the surface. Installation requires cutting a round hole to the correct diameter (approximately 140–145mm depending on the cutout specification — confirm with GME) and a depth sufficient for the speaker basket. The grille then sits flush to the panel.
163mm is the outer diameter of the speaker. The actual panel cutout will be slightly smaller — typically around 140–145mm for a speaker of this size. Confirm the exact cutout diameter with GME before cutting the panel. A 163mm speaker fits most standard marine panel cutout templates.
The S5BG is specifically listed as optional black grilles for the GS500, suggesting they are designed to replace the included white grilles for a contrasting or all-dark appearance. Confirm with GME whether the S5BG is a direct swap for the standard white grilles included with the GS500W.
For best performance and longevity, use an amplifier rated at 75–110W RMS per channel at 4Ω. Underpowering speakers (using a significantly lower power amplifier) can cause distortion at high volume, which may damage the speaker. The GME GR350BTW marine stereo outputs 4 × 40W — functional but understated for 110W speakers; a dedicated marine amplifier would allow the GS500 to perform at its rated capability.
The GS320W is GME's smallest marine box speaker at 109 × 96mm with 60W per speaker. The GS500 is a larger flush mount speaker at 163mm with 110W per speaker. The GS500 provides more power and the flush mount installation style; the GS320W suits tighter spaces where a round cutout is not possible. Choose based on available panel space and preferred installation method.
