Tectonic PL-11 Resonant Mode Loudspeaker - Black

The Tectonic PL-11 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-11 is a passive speaker system comprised of a single Distributed Mode Loudspeaker (DML) and a large format ribbon transducer / horn. System frequency response is 90Hz – 20kHz (+-3dB) 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’s diffuse output has a frequency response of ~ 90Hz to 9kHz with no cross-over network that can introduce phase and time alignment issues or possible distortion.

The PL-11 DML has a horizontal and vertical coverage of 165⁰, is feed-back resistant and generates near-zero amounts of odd-order harmonic artifacts and distortion. The net effect is superior intelligibility throughout a venue.

The PL-11’s DML propagates wide and diffuse audio that interacts with boundaries, (walls, windows, floors and ceilings), in an equally diffuse manner. The PL-11 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-11 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.

Complementing the PL-11’s DML is an integrated large-format ribbon transducer with a nominal frequency response of ~6kHz – 22kHz. A shallow horn design provides HF distribution of 120⁰ horizontal by 15⁰ vertical.

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

PL-11s can be stand-mounted or flown from their integral mounting system designed by Tectonic and engineered & certified by ATM™. PL-11s are also VESA mount compatible for floor stands, wall-mount and swing-arm applications.
