The Dayton Audio DMA105-4 4" Aluminum Cone Full-Range Driver delivers impressively clear and balanced sound from a compact footprint, making it an excellent choice for DIY audio enthusiasts and professional designers alike. This versatile driver is ideally suited for use in small bookshelf speakers, multimedia monitors, portable Bluetooth enclosures, or as a dedicated midrange in multi-way systems where space is at a premium. Its full-range capability means it can handle both vocals and instrumental detail with remarkable transparency, while still providing satisfying bass response for its size.

Engineered for reliable performance, the DMA105-4 features a lightweight yet rigid aluminium cone that ensures low distortion and fast transient response. The copper voice coil offers efficient heat dissipation and stable impedance, contributing to a sensitivity of 89.8 dB at 2.83V/1m. With a total Q factor (Qts) of 0.51 and a maximum linear excursion (Xmax) of 2.5 mm, this driver is well-suited for both sealed and ported enclosures. The 4-ohm impedance (Re: 3.4 ohms) allows for easy pairing with a wide range of amplifiers. Compact dimensions—just 104.1 mm square with a mounting depth of 47.2 mm—and a standard 89.9 mm cutout diameter simplify integration into tight spaces. Whether you are upgrading an existing design or building from scratch, the DMA105-4 offers a compelling blend of clarity, efficiency, and build quality.
