Description
The DML25-4 2" full-range transducer from Dayton Audio produces an amazing amount of quality sound on and off-axis while maintaining a small form factor. Designed to behave like a conventional pistonic driver at lower frequencies and a DML (distributed mode loudspeaker) at higher frequencies, this driver's unique shape lends itself to modern audio applications, such as speaker bars, docking stations, and satellite speakers, where sound is to be heard without the source being seen.
Features
- Unique, square-shaped from for tight driver-to-driver placement.
- Extended frequency response up to 15,000 Hz due to low a inductance motor.
- Wide off-axis dispersion for placement flexibility.
- Perfect for modern audio applications such as speaker bars and line arrays.
