Flat-panel loudspeaker manufacturer Tectonic Audio Labs has produced a 21-part technical video series explaining the function, performance and application of its Distributed Mode Loudspeaker (DML) technology.
Unlike traditional loudspeaker systems which utilise pistonic cone and compression drivers to produce audio, Tectonic speakers employ large-format, flat-panel DML resonant-mode devices, "[producing] audio in a fundamentally different way to a typical loudspeaker", says Tectonic's Tim Whitwell. "This technology can seem quite counterintuitive to those not familiar with resonant-mode devices."
The Tectonic Technical Video Series condenses over three hours of conversations between Whitwell and transducer/ loudspeaker systems engineer Marcelo Vercelli, who explore and explain DML technology. Each five-minute video module covers a single topic – which include 'How DMLs work, 'DMLs vs pistonic transducers', 'DML feedback resistance', 'DMLs in reverberant spaces' and 'DML stereo imaging' – in detail.
"We set up a video library [...] that allows visitors to easily browse and sample topics of interest," says Tectonic marketing director Scott Garside. "There is a wealth of information here that provides a fundamental understanding of resonant-mode audio propagation. The function and benefits of DMLs are quite remarkable."
The first video in the series, an introduction to the Tectonic Technical Video Series by Whitwell and Vercelli, is embedded below.
