The Dayton Audio DSA90-8 3" Designer Series Aluminum Cone Full-Range Driver offers an exceptional solution for achieving clear, detailed audio reproduction in compact loudspeaker designs. This 8-ohm driver is engineered to deliver low-distortion sound across a wide frequency band, making it an ideal choice for high-fidelity applications where space is at a premium.

Perfectly suited for use in desktop monitors, surround sound systems, and portable Bluetooth speakers, this full-range driver excels in scenarios where a single driver must cover the majority of the audible spectrum. Its robust construction also makes it a popular choice for automotive audio upgrades and custom DIY projects requiring a compact yet capable sound source.

Technically, the DSA90-8 features a rigid aluminium cone and a copper voice coil, which together minimise distortion and improve transient response. With a sensitivity of 84.7 dB SPL at 2.83V/1m and a total Q factor of 0.37, it offers a well-damped response suitable for sealed or small vented enclosures. The 2.5mm linear excursion (Xmax) and 7.8cc displacement volume (Vd) ensure solid output for its size, while the 0.53mH voice coil inductance helps maintain clarity at higher frequencies. The driver’s 70mm cut-out diameter and four mounting holes simplify integration into existing designs.

Combining audiophile-grade performance with a compact footprint, the DSA90-8 is a versatile choice for discerning builders and designers seeking full-range fidelity.
