Finished in RAL 9011 black with a durable polyurea coating and IP54-rated enclosure, the PL-SUB18 is purpose-built for permanent venue installations where reliability and performance cannot be compromised.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eBuilt around an 18-inch woofer with a 4-inch voice coil housed in a bass-reflex enclosure constructed from exterior-grade plywood, the PL-SUB18 delivers up to 138 dB peak SPL and extends usable bass response to 35 Hz (–6 dB). The enclosure features integrated retractable rigging hardware, allowing arrays of up to 10 PL-SUB18 units — or combined arrays of 3 PL-SUB18 plus 10 PL-LA12 line array elements — to be flown safely. The input cup is IP65-rated and accepts dual Speakon NL4 connectors plus a 4-pole Euroblock, ensuring flexible wiring and a weatherproof seal. When deployed in pairs or larger groupings, the PL-SUB18 supports cardioid bass configurations via Q-SYS processing, allowing installers to reduce rear-firing energy and maximize front-of-house coverage. The hydrophobic stainless steel mesh grille and UV\/corrosion-treated steel face add durability suited for semi-outdoor or challenging indoor environments.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e18-inch neodymium-motor woofer with 4-inch (101.6 mm) voice coil\u003c\/li\u003e\n\u003cli\u003e97 dB sensitivity (1 W\/1 m); 138 dB peak SPL\u003c\/li\u003e\n\u003cli\u003e750 W continuous \/ 1500 W rated power handling at 8 ohms\u003c\/li\u003e\n\u003cli\u003eFrequency response: 38 Hz – 82 Hz (–3 dB); 35 Hz – 90 Hz (–6 dB)\u003c\/li\u003e\n\u003cli\u003eIP54-rated bass-reflex enclosure in exterior plywood with polyurea paint\u003c\/li\u003e\n\u003cli\u003eIP65-rated input cup with 2× Speakon NL4 + 1× 4-pole Euroblock\u003c\/li\u003e\n\u003cli\u003eIntegrated retractable rigging — flyable up to 10 units or combined PL-LA12 arrays\u003c\/li\u003e\n\u003cli\u003eHydrophobic stainless steel mesh grille with UV and corrosion treatment\u003c\/li\u003e\n\u003cli\u003eOmnidirectional or cardioid bass deployment (cardioid requires 2+ units with Q-SYS processing)\u003c\/li\u003e\n\u003cli\u003eNominal impedance: 8 ohms (minimum 6 ohms)\u003c\/li\u003e\n\u003cli\u003eRAL 9011 black finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTypical Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHouses of worship with high-output sound reinforcement requirements\u003c\/li\u003e\n\u003cli\u003ePerforming arts centers and concert halls\u003c\/li\u003e\n\u003cli\u003eNightclubs, live music venues, and ballrooms\u003c\/li\u003e\n\u003cli\u003eStadiums, arenas, and large multipurpose facilities\u003c\/li\u003e\n\u003cli\u003eOutdoor amphitheaters and covered stages (with appropriate weather protection)\u003c\/li\u003e\n\u003cli\u003eFlown subwoofer arrays in touring or permanent theatrical installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eWoofer Size\u003c\/th\u003e\n\u003ctd\u003e18 in (460 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVoice Coil Diameter\u003c\/th\u003e\n\u003ctd\u003e4 in (101.6 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEnclosure Type\u003c\/th\u003e\n\u003ctd\u003ePassive bass-reflex\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSystem Sensitivity\u003c\/th\u003e\n\u003ctd\u003e97 dB (1 W\/1 m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFrequency Response (–3 dB)\u003c\/th\u003e\n\u003ctd\u003e38 Hz – 82 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFrequency Response (–6 dB)\u003c\/th\u003e\n\u003ctd\u003e35 Hz – 90 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax SPL Continuous\u003c\/th\u003e\n\u003ctd\u003e126 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax SPL Peak\u003c\/th\u003e\n\u003ctd\u003e138 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Handling — Continuous\u003c\/th\u003e\n\u003ctd\u003e750 W @ 8 Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Handling — Rated\u003c\/th\u003e\n\u003ctd\u003e1500 W @ 8 Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNominal Impedance\u003c\/th\u003e\n\u003ctd\u003e8 Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMinimum Impedance\u003c\/th\u003e\n\u003ctd\u003e6 Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConnectors\u003c\/th\u003e\n\u003ctd\u003e2× Speakon NL4, 1× Euroblock 4-pole (IP65 input cup)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions (H × W × D)\u003c\/th\u003e\n\u003ctd\u003e20.9 × 24.4 × 29.2 in (532 × 620 × 741 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight (Net)\u003c\/th\u003e\n\u003ctd\u003e102.2 lbs (46.3 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eBlack (RAL 9011)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEnclosure Material\u003c\/th\u003e\n\u003ctd\u003eExterior plywood, polyurea paint, IP54\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGrille\u003c\/th\u003e\n\u003ctd\u003e16 GA steel, hydrophobic stainless steel mesh\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRigging\u003c\/th\u003e\n\u003ctd\u003eIntegrated retractable rigging; flyable up to 10× PL-SUB18 or 3× PL-SUB18 + 10× PL-LA12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eFAQs\u003c\/h2\u003e\u003cdl\u003e\n\u003cdt\u003eCan the PL-SUB18-BK be used outdoors?\u003c\/dt\u003e\n\u003cdd\u003eThe PL-SUB18 enclosure is IP54-rated and the grille uses hydrophobic stainless steel mesh, making it suitable for covered or semi-outdoor installations.
