The Dayton Audio DMA45-8 is a compact 1.5-inch full-range driver engineered to deliver remarkably clear and balanced audio from even the smallest enclosures. Featuring a lightweight aluminium cone, this driver is ideally suited for portable Bluetooth speakers, desktop monitors, and other space-constrained designs where high-quality sound reproduction is essential without compromising on size. Its full-range capability makes it a versatile choice for DIY audio projects or upgrading existing compact systems.

Technically, the DMA45-8 boasts a total Q factor (Qts) of 0.59, ensuring a well-damped response that works seamlessly in small sealed or ported boxes. With a sensitivity of 76.9 dB (1m/2.83V) and a maximum linear excursion (Xmax) of 2 mm, it offers efficient performance with low distortion. The copper voice coil and aluminium cone provide excellent thermal management and rigidity, while the 4-hole mounting pattern and 39.9 mm cutout diameter simplify installation. Its 7-ohm DC resistance (Re) and 0.4 mH voice coil inductance contribute to stable impedance characteristics.

This driver is a superb choice for audiophiles and makers seeking a high-fidelity, full-range solution in a miniature footprint, delivering articulate vocals and detailed highs without the need for a separate tweeter.
