PL-11NR Coverage Sm-1


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 Tectonic or 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, provides a high margin of feedback resistance and generates near-zero amounts of odd-order harmonic artifacts and distortion. The net effect is superior intelligibility throughout a venue.


The PL-11NR propagates wide and diffuse audio that interacts with boundaries, (walls, windows, floors and ceilings), in an equally diffuse manner. The PL-11NR does not generate audio energy that is reflected as coherent first, second, third reflections that are perceived as out of phase, time-related reflections,  so the acoustic space is essentially “erased”.

Even with such a diffuse output, the PL-11NR creates a highly accurate stereo image that is also propagated throughout its very wide output. Nearly every location throughout a venue perceives a stereo image.


Compact Form Factor

The form factor of the PL-11NR is remarkable for its performance. Measuring approximately 3 feet wide by 2 feet tall by 3 inches deep, the PL-11NR can serve well as single panel stereo pairs for small venues mounted on stands, hung in small-multiples for increased output or as large multiple arrays when extended vertical coverage and space are a consideration.

Versatile Deployment

PL-11NRs can be stand-mounted or flown from their integral mounting system designed by Tectonic and engineered & certified by ATM™. PL-11NRs are also VESA mount compatible for floor stands, wall-mount and swing-arm applications.
Rigging hardware as shown or described is optional and available at additional charge.

Efficient to Own and Operate

PL-11NRs are highly efficient; delivering more acoustic output for electrical input, A typical system for 1,000 seats can be powered by a single 110v 20A outlet. Touring and/or shipping a PL-11NR system is extremely compact and affordable.

PL-11NRs are available in a limited number of custom colors

Matching or contrasting grill cloth is available.

Optional acoustically transparent socks are available in custom colors and /or graphics for color matching or branding.
