DML25-4 2" Distributed Mode Loudspeaker Transducer 20W 4 Ohm

Quick Overview

Dayton Audio's DML25-4 2" full-range DML speaker combines the compactness of an exciter with the pistonic air modulation of a standard speaker, making it perfect for use in sound bars and compact speakers where smooth off-axis response is needed.

Product Highlights

  • Unique, square-shaped from for tight driver-to-driver placement
  • Extended frequency response up to 15,000 Hz due to low inductance a motor
  • Wide off-axis dispersion for placement flexibility
  • Perfect for modern audio applications such as speaker bars and line arrays

Dayton Audio DML25-4 Specifications

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) and higher frequencies, this driver's unique shape lends itself to modern audio applications, such as a speaker bars, docking stations, and satellite speakers, where sound is to be heard without the source being seen.

Great off-axis directivity enables flexible placement options, while the wide frequency response (that extends from 150 Hz up to 15,000 Hz) delivers cost savings to engineers... no crossover components or frequency-specific drivers are required. The Dayton Audio DML25-4 is a natural selection for designing and building anything from thin column line array speakers to ultra-compact smart speakers.
