Its IP54-rated black enclosure, integrated rigging points, and IP65-rated input cup make it a versatile choice for flown or ground-stacked configurations in permanent venues.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe PL-SUB15 houses a 15-inch woofer with a 4-inch voice coil in a bass-reflex enclosure built from exterior-grade plywood with polyurea paint. It delivers 124 dB continuous SPL and 136 dB peak SPL, with frequency response extending to 38 Hz (–6 dB). The enclosure includes four M10 bottom rigging points and four M10 side rigging points, enabling integration with the PL-CA12 loudspeaker for combined column arrays. The IP65-rated input cup provides dual Speakon NL4 connectors plus a 4-pole Euroblock for flexible amplifier connection. Like all PL Series subwoofers, the PL-SUB15 supports cardioid bass configuration when deployed in pairs or more, using Q-SYS processing to control directivity and minimize rear-stage energy buildup. The hydrophobic stainless steel mesh grille adds durability for environments with elevated humidity or dust exposure.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e15-inch woofer with 4-inch (100 mm) voice coil\u003c\/li\u003e\n\u003cli\u003e96 dB sensitivity (1 W\/1 m); 136 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: 41 Hz – 93 Hz (–3 dB); 38 Hz – 104 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\u003e4× M10 bottom and 4× M10 side rigging points; links to PL-CA12\u003c\/li\u003e\n\u003cli\u003eHydrophobic stainless steel mesh grille\u003c\/li\u003e\n\u003cli\u003eOmnidirectional or cardioid bass deployment (cardioid requires 2+ units)\u003c\/li\u003e\n\u003cli\u003eNominal impedance: 8 ohms (minimum 6.8 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 medium-to-large sanctuaries\u003c\/li\u003e\n\u003cli\u003ePerforming arts centers, theaters, and auditoriums\u003c\/li\u003e\n\u003cli\u003eNightclubs, live music venues, and entertainment spaces\u003c\/li\u003e\n\u003cli\u003eHotel ballrooms and conference centers\u003c\/li\u003e\n\u003cli\u003eCorporate event spaces and multipurpose rooms\u003c\/li\u003e\n\u003cli\u003eFlown or ground-stacked subwoofer configurations in permanent 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\u003e15 in (380 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVoice Coil Diameter\u003c\/th\u003e\n\u003ctd\u003e4 in (100 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\u003e96 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\u003e41 Hz – 93 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFrequency Response (–6 dB)\u003c\/th\u003e\n\u003ctd\u003e38 Hz – 104 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax SPL Continuous\u003c\/th\u003e\n\u003ctd\u003e124 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax SPL Peak\u003c\/th\u003e\n\u003ctd\u003e136 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\u003e6.8 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\u003eRigging\u003c\/th\u003e\n\u003ctd\u003e4× M10 bottom, 4× M10 side; links to PL-CA12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions (H × W × D)\u003c\/th\u003e\n\u003ctd\u003e15 × 23.5 × 27.1 in (380 × 598 × 690 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight (Net)\u003c\/th\u003e\n\u003ctd\u003e80 lbs (36.3 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\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eFAQs\u003c\/h2\u003e\u003cdl\u003e\n\u003cdt\u003eCan the PL-SUB15-BK be integrated with PL-CA12 loudspeakers?\u003c\/dt\u003e\n\u003cdd\u003eYes.
