It pairs a glass fiber woofer with a PEI dome tweeter, delivering accurate response from 115 Hz to 22 kHz and 3-ohm impedance for easy integration with modern amps.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eNominal Diameter\u003c\/b\u003e: 4\" (101.6mm) – a compact woofer size that fits many 4\" mounting openings in doors or dash panels while still delivering audible bass and detailed highs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eNominal Impedance\u003c\/b\u003e: 3 ohm – lower impedance offers higher current delivery when used with compatible amplifiers, helping the system achieve more output from the same amp.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRMS Power Handling\u003c\/b\u003e: 60W – continuous power the driver can reliably handle; keep amplification within this range to preserve clarity and longevity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMAX Power Handling\u003c\/b\u003e: 260W – peak capability for brief transients; provides headroom for dynamic music without immediate clipping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSensitivity (1W\/1m)\u003c\/b\u003e: 85 dB – efficiency metric used to estimate the expected SPL with a given amp and listening distance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFrequency Response\u003c\/b\u003e: 115Hz – 22kHz – covers most vocal and mid-to-high content; deep bass may require a subwoofer in a full-range system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRecommended HI Pass Crossover\u003c\/b\u003e: 140Hz – suggested high-pass filter to protect the woofer from too-low frequencies and optimize mid-bass performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eNumber of Ways\u003c\/b\u003e: 2-way – separate woofer and tweeter provide clearer highs and more accurate vocal reproduction than a single-driver design.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eGrill Included\u003c\/b\u003e: Yes – protective grille included for installation durability and finish.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWoofer Material\u003c\/b\u003e: Glass Fiber – stiff, lightweight cone reduces distortion and improves transient response for cleaner bass and mids.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSurround Material\u003c\/b\u003e: Rubber – durable edge material that tolerates movement and temperature changes in automotive environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTweeter Material\u003c\/b\u003e: PEI Dome; Magnet Material Neodymium – rigid high-frequency diaphragm paired with strong magnets for detailed highs and efficient motor structure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eVoice Coil Diameter\u003c\/b\u003e: 1\" (25.5mm) – robust coil support for reliable performance under musical transients.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eVoice Coil Former Material\u003c\/b\u003e: BASV\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWinding Material\u003c\/b\u003e: CCAW\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBasket Material\u003c\/b\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMagnet Material\u003c\/b\u003e: Neodymium\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOverall Diameter\u003c\/b\u003e: 4.12\" (104.8mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOverall Depth\u003c\/b\u003e: 2.14\" (54.5mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFront Mount Baffle Cutout\u003c\/b\u003e: 3.77\" (96mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMounting Depth\u003c\/b\u003e: 1.96\" (50mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWeight\u003c\/b\u003e: 4 lb per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn a typical front-stage install, the EXL-SQ4.0’s 2-way design delivers crisp highs and controlled midbass from a compact enclosure while the 3-ohm impedance and neodymium magnets support strong, responsive output when paired with a suitable amplifier. The glass fiber cone minimizes distortion during musical transients, and the 140 Hz high-pass recommendation helps protect the woofer in space-constrained builds. The included grill and rigid aluminum basket simplify mounting and finish, making this 4\" coaxial a precise choice for enthusiasts building clean, mid- to high-end door or dash systems.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"DS18","offers":[{"title":"Default Title","offer_id":49850246693092,"sku":null,"price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0842\/2522\/9028\/files\/EXL-SQ4-COVER_700x_4faa0fbc-3305-481d-aeca-00b3043e75d3.webp?v=1789261814","url":"https:\/\/www.12voltoutlet.com\/products\/ds18-exl-sq4-0-exl-4-2-way-coaxial-speaker-with-fiber-glass-cone-340-watts-3-ohm","provider":"12 Volt Outlet","version":"1.0","type":"link"}
