What is DML Technology?

Distributed Mode Loudspeaker technology utilizes planar wave physics to deliver professional-grade, full frequency audio via rigid panels (drywall, ceilings, ceiling tiles, window panes, wood cabinets, etc.). The sound created by DML technology is similar to that created from the body of an acoustic guitar or piano soundboard – high fidelity and completely immersive.

It’s like having a wall full of speakers, creating a massive planar acoustic wave. This wave radiates out evenly from the surface, providing constant sound pressure level (SPL) throughout the listening space – unlike the uneven pattern provided by traditional cone speakers. Because there are no hot spots in the audio, feedback loops into microphones are also eliminated.

Revolution Acoustics products are protected by numerous US and worldwide patents.

The problems: Beaming, “Hot and Cold” spots, very small “sweet spots” for listening

Conventional cone speakers “beam” the sound signal in a conical pattern, leaving large areas of the room without effective coverage.

The higher the frequencies, the more pronounced the beam effect. The result is muddy audio as you move off-axis from the center of the speaker. You also experience “hot” and “cold” audio from the speaker’s coverage, either too loud or not loud enough. The beaming effect creates a third problem, that of “sweet spots”. In home installations, careful attention is paid to placement of chairs in a listening area to ensure that ears are in line with the cone speakers’ high frequency content. This greatly limits what you can do with room setup and also makes it difficult for anyone moving around a room to enjoy the audio experience.

The Solution:

Revolution Acoustics SSP6 Multiducers™ solve this problem by equally radiating all frequencies across the space of the panel, using bending wave physics.

With Revolution Acoustics technology, sound is consistent across the entire plane. It diminishes at a rate of its distance (1/d) so at the same 10 foot distance from the radiating surface, the sound quality is orders of magnitude better than audio coming from cone speakers, and completely fills the room. For stereo or surround imaging, multiple SSP6 units can be separated within the space to build a “bubble” of sound that intersects for a whole-room sweet spot (or sweet “area”).

The Value Proposition:

Revolution Acoustics speakers can save time and money.

Because conventional speakers have conical waveforms, you need to install many of them in order to more effectively cover an area – and you still end up with hot and cold spots and off-axis muddiness.

Superior coverage can be achieved in the same space using fewer Revolution Acoustics SSP6 units. This brings a substantial savings in installation time and requires less wiring. Because the SSP6 was designed for high power handling, even high-acoustic-energy installations such as bars can take advantage of the Revolution Acoustics solution.

Magic? Not really – it’s just good science put to work to help resolve nearly all sound reinforcement applications.
