The 30oz magnet structure and poly injection cone deliver solid output for the size, while the 1\" Mylar dome tweeter handles high-frequency clarity. Black grilles suit dark-hardware helm stations and modern boat aesthetics.\u003c\/p\u003e\u003cp\u003eAt 90dB sensitivity and 4 ohm impedance, these speakers are compatible with most marine head units and receiver packages without requiring an external amplifier.

The 90dB sensitivity means they’ll perform well with standard marine head units without needing an amplifier. The black finish suits dark-hardware and modern helm aesthetics. If your mounting location accommodates 6.5\", the larger speaker format will generally deliver better low-frequency output and overall volume.\u003c\/p\u003e\u003ch3\u003eAlso Consider\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/boss-audio-mrgb65-6-5-inch-2-way-marine-speakers-rgb-lighting-white\"\u003eBoss Audio MRGB65 6.5\" Marine Speakers with RGB Lighting — White\u003c\/a\u003e — larger format with RGB accent lighting\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/boss-audio-mck632wb64-marine-audio-kit-receiver-2-pairs-6-5-speakers-antenna-white-153-mck632wb64\"\u003eBoss Audio MCK632WB64 Marine Audio Kit\u003c\/a\u003e — complete system with receiver and 6.5\" speakers\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/products\/boss-audio-tube-portable-marine-bluetooth-speaker-ipx5\"\u003eBoss Audio TUBE Portable Marine Bluetooth Speaker\u003c\/a\u003e — portable, no-install option\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/navigation-and-electronics\"\u003eBrowse all Navigation \u0026amp; Electronics\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eSKU 153-MR50B follows the Boss Audio prefix pattern used throughout this catalog — brand attribution as Boss Audio should be confirmed with the supplier if the customer asks for brand confirmation. The 5.25\" size is the key selection factor: confirm the customer’s mounting cutout diameter before recommending this vs. the 6.5\" models. The 4 ohm impedance is standard and compatible with virtually all marine head units. The 150W peak rating is a marketing figure — the continuous\/RMS rating is not listed in the available data; confirm with supplier if a customer asks for RMS output. No RMS wattage or waterproof\/weatherproof rating is listed in the available product data — confirm both with supplier before sale if the customer asks.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":50971572142116,"sku":"153-MR50B","price":97.19,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/images_f5406890-37ef-4bbb-baac-49806a423f29.jpg?v=1785549458","url":"https:\/\/marisolmarine.com\/products\/boss-audio-mr50b-5-25-inch-2-way-marine-speakers-black-pair","provider":"Marisol Marine Company","version":"1.0","type":"link"}
