The Tectonic PL-11NR Flat Panel Loudspeaker is an ideal choice for small to medium -sized venues where an equal audio experience for all seats across a very wide listening area is required. The PL-11NR is a passive speaker system comprised of a single Distributed Mode Loudspeaker (DML). 180 degree frontal hemispherical power response is 100Hz – 20kHz (+/-6dB) and is used in conjunction with third-party subwoofers. The DML utilizes resonant mode acoustic physics to propagate very wide, diffuse audio energy into a given space. The DML requires no cross-over network that can introduce phase and time alignment issues or possible distortion. The PL-11NR has a horizontal and vertical coverage of 165⁰, is feedback resistant and generates near-zero amounts of odd-order harmonic artifacts and distortion. The net effect is superior intelligibility throughout a venue.
