Tectonic Audio Labs has expanded its line of flat-panel loudspeakers with the addition of the DML500. Based upon Tectonic’s patented Distributed Mode Loudspeaker technology, the DML500 is a diffuse di-pole loudspeaker employing a carbon-fiber composite panel coupled to four highly optimized electro-dynamic transducers.

This unique design produces audio across a broad frequency range, delivering exceptional intelligibility with an extremely wide and predominantly diffuse coverage pattern of 160 degrees in the horizontal and vertical planes. Frequency response for the DML500 is stated as 90 Hz to 20 kHz ±6 dB, with a 10dB down point of 75 Hz.

Unlike traditional loudspeakers, Distributed Mode Loudspeakers produce sound by creating complex bending wave vibration patterns that set air into motion. The resulting effect is a single, large source that disperses audio in a very wide and diffuse manner throughout the listening area. The flat-panel design and light weight of the DML500 provides a high degree of flexibility in placement and mounting.

The DML500 has a nominal impedance of 8 Ohms, and an input sensitivity of 91 dB, when used with Tectonic’s recommended EQ settings. Power handling is spec’d as 300 watts program and 400 watts peak (at 8 Ohms). When used in high-output systems, Tectonic recommends using a highpass filter at 110 Hz, enabling the DML500 to work effectively from this frequency up to 20 kHz.

Dimensions for the DML500 are 31.5 W x 21.6 H x 3.5 D (inches). It weighs in at 44 pounds, making it Tectonic Audio Labs’ smallest and lightest Distributed Mode Loudspeaker.
