Dayton Audio DML25-4 Balanced Mode 2" Transducer

The Dayton Audio DML25-4 is a 2-inch Distributed Mode Loudspeaker transducer, engineered to deliver clear, wide-dispersion sound from an exceptionally compact form. As a broadband subwoofer, it excels in applications where traditional speakers cannot be accommodated, making it an ideal choice for flat-panel audio systems, architectural installations, and immersive distributed audio setups. Its unique operating principle allows it to excite surfaces such as walls, ceilings, or display panels, turning them into large, coherent sound sources that fill a room with natural, evenly distributed audio.

Technically, this transducer features a paper cone and a powerful neodymium magnet, ensuring efficient performance and a lightweight design. With a nominal impedance of 4 ohms and a power handling of 20 watts, it is well-suited for low-power amplification. The total Q factor (Qts) of 1.1, along with a mechanical Q (Qms) of 3.83 and an electrical Q (Qes) of 1.5, indicates a damped response ideal for distributed mode operation. The maximum linear excursion (Xmax) of 1.5 mm and a DC resistance (Re) of 4.3 ohms further define its precise electrical characteristics. The polymer basket and neodymium magnet contribute to its durability and compact dimensions of 66.8 × 66.8 mm with a depth of 26.4 mm, while the 59.4 mm cutout diameter and four mounting holes simplify installation. Part of the Dayton Audio Specialty Drivers series, the DML25-4 offers a unique solution for achieving high-quality, wide-dispersion sound in tight spaces.
