Featuring LEAF Waveguide technology and a 90 x 15 degree dispersion pattern, this passive line array module delivers controlled vertical coverage with high SPL for demanding indoor and covered outdoor applications. The black (RAL 9011) impact-resistant ABS enclosure supports passive and bi-amp operation and integrates with PL-SUB18 subwoofers for flown sub-array systems. It is a purpose-built solution for scalable, high-output installed line array deployments.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe PL-LA12 pairs a 12-inch neodymium LF transducer with a 2.5-inch voice coil and dual 1-inch exit compression drivers to deliver a system bandwidth of 59 Hz to 20 kHz (-3 dB). System sensitivity is 102 dB (1 W\/1 m), with continuous SPL reaching 119 dB passive and 123 dB bi-amped. The bass reflex enclosure can be ground-stacked up to 3 cabinets or flown up to 12 cabinets, and supports hybrid arrays of 3x PL-SUB18 plus 10x PL-LA12, all requiring the PL-LA12-AF array frame. Eight discrete rigging angles from 0.5 to 12 degrees allow precise vertical splay tuning. QSC LEAF Waveguide technology shapes the HF wavefront for consistent coverage and reduced lobing across the array. Connectivity includes two Speakon NL4 connectors and a parallel locking 4-pole Euroblock in an IP65-sealed input cup. IP54 weatherization with stainless hardware, a UV-treated grille, and hydrophobic mesh supports challenging fixed-install environments. At 43 lbs, the cabinet delivers high output density for permanent reinforcement systems.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLEAF Waveguide Technology\u003c\/strong\u003e — Shapes the HF wavefront for consistent coverage and minimized lobing across the array.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e90 x 15 Degree Coverage\u003c\/strong\u003e — Long-throw horizontal pattern with tight vertical control for larger venues.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual HF Compression Drivers\u003c\/strong\u003e — Two 1-inch exit drivers extend high-frequency output and headroom.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePassive or Bi-Amp Operation\u003c\/strong\u003e — Selectable crossover at 1.5 kHz passive or 1.2 kHz bi-amp adapts to varied system architectures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlyable With PL-SUB18\u003c\/strong\u003e — Supports hybrid arrays of 3x PL-SUB18 and 10x PL-LA12 for integrated low-end.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScalable Deployment\u003c\/strong\u003e — Ground-stack up to 3 or fly up to 12 cabinets with the PL-LA12-AF array frame.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEight Rigging Angles\u003c\/strong\u003e — Discrete splay settings from 0.5 to 12 degrees enable precise array shaping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP54 Weatherization\u003c\/strong\u003e — Stainless hardware, UV-treated grille, and hydrophobic mesh support covered outdoor use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP65 Sealed Input Cup\u003c\/strong\u003e — Dual Speakon NL4 and parallel Euroblock connectors protected against moisture ingress.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTypical Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAuditorium — long-throw arrays delivering high SPL and intelligibility across deep seating.\u003c\/li\u003e\n\u003cli\u003eHouse of worship — full-range music and speech reinforcement for large sanctuaries.\u003c\/li\u003e\n\u003cli\u003eMulti-purpose room — scalable coverage for concerts, conferences, and assemblies.\u003c\/li\u003e\n\u003cli\u003eBroadcast studio — controlled coverage with extended low-frequency response for production audio.\u003c\/li\u003e\n\u003cli\u003eCommercial meeting space — high-output reinforcement for large all-hands and event venues.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x:auto;\"\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eTwo-way passive\/bi-amp installation line array, bass reflex\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLF Transducer\u003c\/td\u003e\n\u003ctd\u003e12 in (305 mm), 2.5 in (63.5 mm) voice coil, neodymium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHF Transducer\u003c\/td\u003e\n\u003ctd\u003e2x compression driver, 1 in (25.4 mm) exit, 1.75 in (44.5 mm) voice coil\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoverage (H x V)\u003c\/td\u003e\n\u003ctd\u003e90 x 15 degrees\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Bandwidth (-3 dB)\u003c\/td\u003e\n\u003ctd\u003e59 Hz - 20 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrossover\u003c\/td\u003e\n\u003ctd\u003e1.5 kHz (passive);
