2-WAY SYSTEM WITH two DMLs (DISTRIBUTED MODE LOUDSPEAKER) & ONE RIBBON (HF)

PL12_Angled_Left-A_Sep_Web

 

Overview

The Tectonic PL-12 Flat Panel Loudspeaker is an ideal choice for medium to large spaces where very wide coverage, high output and extended duty - cycles are required.

The PL-12 is a passive speaker system comprised of a pair of Distributed Mode Loudspeakers (DMLs) and a large format ribbon transducer / horn.

The DMLs utilize resonant mode acoustic physics to propagate very wide, diffuse audio energy into a given space. The DMLs’ 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-12 DMLs have a horizontal and vertical coverage of 165⁰, are feed-back resistant and generate near-zero amounts of odd-order harmonic artifacts and distortion. The net effect is superior intelligibility throughout a venue.

The PL-12 DMLs propagate a very wide and diffuse audio that interacts with boundaries, (walls, windows, floors and ceilings), in an equally diffuse manner. The PL-12 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-12 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-12’s DMLs 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.

Compact Form Factor

The form factor of the PL-12 is remarkable for its performance. Measuring approximately 5 feet wide by 2 feet tall by 3 inches deep, the PL-12 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 is required.

Versatile Deployment

PL-12s can be stand-mounted or flown from their integral mounting system designed by Tectonic and engineered & certified by ATM™. PL-12s are also VESA mount compatible for floor stands, wall-mount and swing-arm applications.
(Rigging options illustrated and/or describe are optional and available at an extra cost.)

Efficient to Own and Operate

PL-12s are highly efficient; delivering more acoustic output for electrical input, A typical system for 3,000 - 5,000 seats can be powered by a pair of 110v 20A circuits. Touring and/or shipping a PL-12 system is extremely compact and affordable.

Available in custom colors

PL-12s can be ordered 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.
