Two-way passive installation line arrays

The Q-SYS PL-LA family are two-way, passive installation line arrays designed that deliver premium sound for a broad range of applications, from entertainment and small sporting venues to corporate auditoriums or higher ed lecture halls. Two models (8-in and 12-in) provide a high-performance front-of-house solution ideal for small to medium sized venues. They feature the QSC Length-Equalized Acoustic Flare™ (QSC LEAF™) waveguide, providing superior acoustic performance through highly optimized internal sound paths. PL Series performance loudspeakers pair a rich legacy of high-performance audio with the power and flexibility of Q-SYS to extend an integrated audio, video and control experience to your Front-of-House applications.
