White Water Resistant Extension Speaker for GME GX300, GX600A and GX600D 8Ω, 4W Mylar Cone, Gimbal Mount, Lead and Hardware Included Product Overview The GME SPK45 is a white water-resistant extension speaker for the GX300, GX600A, and GX600D marine and CB radio series. It allows received audio to be directed to a second location on the vessel or vehicle, away from the main radio unit particularly useful on larger vessels where the radio speaker cannot be heard clearly from the helm or cockpit, or where the radio is installed in a remote location. The SPK45 features an 8Ω, 4W Mylar cone speaker with metallic dust cap and gimbal mounting for adjustable positioning. The compact 65 × 65 × 64mm enclosure fits in tight spaces. The complete kit includes the lead, plug, mounting bracket, and all mounting hardware. The SPK45 was referenced in GME's GX400 and GX700 marine radio documentation as the recommended optional extension speaker. A black version (SPK45B) is also available for the GX700B installation.

An extension speaker allows the radio's received audio to be heard at a different location from the radio unit itself. On vessels where the radio is installed below deck, in a console, or at a location that's too far from the helm to hear clearly, an extension speaker can be mounted at the operator position for clear audio reception. The SPK45 connects to the radio's external speaker output and provides a second audio point. What is a Mylar cone speaker? Mylar is a polyester film material used for speaker cones in place of traditional paper. Mylar cone speakers are more resistant to humidity and moisture — a significant advantage in marine environments where humidity, salt air, and spray would quickly degrade a paper-cone speaker. The metallic dust cap protects the voice coil and centre of the speaker from direct water and debris contact. What is a gimbal mount? A gimbal mount is a bracket that allows the speaker to pivot or rotate on one or two axes, enabling the speaker face to be angled toward the listener's position rather than being fixed pointing in one direction. This improves audio clarity and volume for the listener. The SPK45's gimbal mount is supplied with hardware for installation. Is a black version of the SPK45 available? Yes — the SPK45B is the black version of this speaker, referenced in GME's GX700B documentation for installations with the black GX700 marine radio. Confirm availability with GME or your supplier. Will the SPK45 work with the GX400 or GX700 marine radios? The SPK45 is referenced in GME's GX400 and GX700 series documentation as the recommended optional extension speaker. The confirmed compatible radios in this listing are the GX300, GX600A, and GX600D. Confirm compatibility for your specific radio model with GME before purchasing.
