DAYTON AUDIO DMA105-4 Full-Range Speaker Driver

The Dayton Audio DMA105-4 is a 4" (Ø10.16 cm) full-range speaker designed to deliver extended and natural sound reproduction in a compact form factor. Compatible with a 4Ω load, it supports 35W RMS (70W max) continuous power handling and offers a sensitivity of 89.8dB (2.83V/1m) with a frequency response ranging from 70Hz to 20kHz. It combines a rigid aluminum cone with a rubber surround, a ventilated 25mm voice coil mounted on an aluminum former, and a dual neodymium magnet structure generating a symmetrical magnetic field for excellent cone control. A large copper cap helps reduce distortion while improving high-frequency response. Its exclusive 12-spoke frame promotes ventilation and minimizes rear reflections, while its design facilitates integration into numerous DIY projects. Thanks to its low distortion, 2.5mm linear excursion, 72.7Hz resonant frequency, and extended response, the DMA105-4 is an excellent choice for Bluetooth speakers, soundbars, compact desktop speakers, line arrays, and high-performance full-range systems.
