Dayton Audio DMA58-4 2" Aluminum Cone Full-Range Driver

The Dayton Audio DMA58-4 2" Aluminum Cone Full-Range Driver delivers impressively clear and coherent sound from a remarkably compact footprint. Engineered as a broadband driver, it is ideally suited for small-scale loudspeaker designs, portable audio projects, and near-field monitoring applications where space is at a premium but audio quality cannot be compromised. Its full-range capability makes it a versatile choice for DIY enthusiasts seeking to build minimalist desktop speakers, multimedia enclosures, or custom installations that demand articulate reproduction across the frequency spectrum.

Technically, this driver features a lightweight yet rigid aluminium cone that ensures fast transient response and reduced distortion. The copper voice coil wire and a total Q factor (Qts) of 0.45 strike an excellent balance between controlled bass extension and smooth midrange performance, making it suitable for both sealed and ported enclosures. With a maximum linear excursion (Xmax) of 2 mm and a sensitivity of 86.2 dB (1m/2.83V), it offers efficient power handling for its size. The 4-hole mounting pattern and a cut-out diameter of 49.8 mm simplify integration into custom baffles. Whether you are upgrading a portable radio or crafting a high-fidelity micro speaker system, the DMA58-4 provides reliable, full-range audio in a compact, high-quality package.
