DAYTON AUDIO DMA45-8 Speaker Driver Full Range

Offering high efficiency and low distortion, Dayton Audio's DMA45-8 is a 3.8cm-diameter full-range aluminum cone speaker driver that can be used for a wide range of modern loudspeaker designs. Whether you're designing a portable Bluetooth speaker, a soundbar, a compact desktop speaker or even a high-output line array, the DMA45-8 is the perfect speaker.

The DMA45-8's uncompromising design delivers excellent performance. Its motor uses two neodymium magnets to create a powerful, symmetrical magnetic field, ensuring high efficiency and excellent diaphragm control. The magnet assembly also includes a large cap and a copper sleeve to reduce inductance and distortion, improving high-frequency response. The two-layer 19mm voice coil is wound on a ventilated polyimide support, ensuring excellent heat dissipation for high power handling and low power compression. A rubber suspension and large spider hold the aluminum diaphragm in place for perfectly linear movement and excellent mechanical damping. In addition, the aluminum dome is attached directly to the coil support to enhance high-frequency response with exceptional off-axis performance. All this is held in a particularly open 8-spoke bowl, favoring excellent ventilation and high excursion.

What's more, Dayton Audio has designed the front panels of all DMA range loudspeakers with DIY enthusiasts in mind. The oversized mounting flange means no precision cutting is required. For ease of installation, the terminals are oriented so that no cuts or notches are needed to clear connectors or wires.
