Here are some of the key advantages of using DML (Distributed Mode Loudspeaker) speakers compared to traditional speaker designs:
Wide Dispersion
- DML panels radiate sound over a large surface area, providing very wide and consistent dispersion across a whole room[1][2][3].
- This gives more consistent coverage compared to traditional speakers with limited sweet spots.
Diffuse Sound
- The diffuse sound produced by the entire panel vibrating creates a spacious, enveloping soundstage[1][2].
- This open and natural sound is different from traditional point source speakers.
Architectural Integration
- DML panels can be mounted flush on walls and ceilings and decorated, allowing seamless architectural integration[1][4].
- Traditional speakers are more obtrusive with limited placement options.
Efficiency
- Properly designed DML speakers can be very efficient, requiring less amplifier power[1][5].
- The ultra-light diaphragm allows high acoustic output from small exciter input.
Cost Effectiveness
- DML panels can be inexpensive to manufacture compared to complex multi-driver speakers[1][4].
- The simple construction allows cost-effective scaling to large sizes.
Drawbacks
- DML speakers lack deep bass and require a subwoofer for full-range reproduction[1][2].
- Sound quality is dependent on proper panel material selection and design[1][3].
Summary
- DML technology provides unique advantages like wide dispersion, architectural integration, and diffuse soundstage over traditional speakers. Proper design is key to realizing the full benefits.
