Certified to Hertz Pure Marine standards including IP65 protection, ASTM-D4329 UV resistance, and ASTM-B117 salt fog operability, the HMX7SLDS is engineered for open water use in high-humidity marine environments. The HMX7SLDS is the grey white colour variant of the HMX7SLDG black grey model, sharing identical specifications. Frequency response spans 45Hz to 25kHz with a mounting depth of 123mm.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eProduct overview\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe HMX7SLDS features a sports paintable ASA plastic grille in grey white with RGB lighting capability for customisable illumination suited to light-coloured vessel interiors and hulls. The polypropylene cone with UV inhibitors and co-moulded Santoprene surround provides long-term durability against UV exposure and moisture. The Aramid fibre spider with silicone-insulated lead wire ensures consistent performance over time in demanding marine environments.\u003c\/p\u003e\n\u003cp\u003eThe 1.4 inch neodymium magnet tweeter uses a PEI dome combined with a faceplate and acoustic lens optimised for off-axis dispersion and high SPL. A sealed built-in crossover with resettable solid-state tweeter protection circuit is integrated into the speaker. Gold-plated corrosion-resistant terminals maintain connection integrity in high-humidity and salt fog environments. The long-throw 32mm voice coil woofer is fine-tuned for infinite baffle applications typical of marine speaker installations.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eFeatures and

Marine 7.7 inch 2-way RGB coaxial speaker pairs with identical specifications, certifications, and construction. The HMX7SLDS is finished in grey white, suited to light-coloured vessel interiors and hulls. The HMX7SLDG is finished in black grey, suited to dark-coloured or sporty vessel interiors. Select based on the colour that best suits your specific vessel aesthetic.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is Hertz Pure Marine Certification?\u003c\/strong\u003e\u003cbr\u003eHertz Pure Marine Certification is Hertz's own marine audio product standard, requiring compliance with IP65 ingress protection, ASTM-D4329 UV resistance testing, and ASTM-B117 salt fog operability testing. Products bearing this certification are confirmed to perform reliably in open water, high-humidity, UV-exposed, and salt fog environments over multiple seasons.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the grille of the HMX7SLDS be painted?\u003c\/strong\u003e\u003cbr\u003eYes. The sports ASA plastic grille is paintable, allowing it to be colour-matched to the vessel's hull or deck finish for a fully integrated aesthetic.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does infinite baffle fine-tuning mean for a marine installation?\u003c\/strong\u003e\u003cbr\u003eInfinite baffle refers to speaker mounting directly into a panel or surface without a rear enclosure, which is the typical mounting method in marine vessel doors, consoles, and panels. The HMX7SLDS woofer is specifically tuned for this mounting configuration, delivering optimised bass performance in marine panel installations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the HMX7SLDS sold as a single speaker or a pair?\u003c\/strong\u003e\u003cbr\u003eThe HMX7SLDS is sold as a matched pair of speakers.\u003c\/p\u003e","brand":"HERTZ","offers":[{"title":"Default Title","offer_id":45000724938845,"sku":"HMX7SLDS","price":599.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0640\/9528\/9437\/files\/HMX7SLDS_600.jpg?v=1788752580","url":"https:\/\/frankiesautoelectrics.com.au\/products\/hertz-hmx7slds-marine-7-7-inch-rgb-coaxial-speaker-pair-grey-white","provider":"Frankies Auto Electrics","version":"1.0","type":"link"}
