Dayton Audio RS225-4 8" Reference Woofer

The Dayton Audio RS225-4 8" Reference Woofer is a high-performance driver engineered to deliver deep, accurate bass and a remarkably clear midrange for discerning audio enthusiasts. As part of the renowned Reference Series, this 4-ohm woofer excels in a variety of applications, including high-fidelity home audio loudspeakers, compact subwoofer systems, and professional studio monitors where precise sound reproduction is paramount. Its robust design makes it equally suitable for sealed and ported enclosures, offering flexibility for custom audio projects.

Technically, the RS225-4 features a rigid aluminium cone that minimises cone breakup and distortion, ensuring controlled, low-colouration output across its frequency range. With a generous 6mm linear excursion (Xmax) and a displacement volume (Vd) of 128.2, it moves substantial air for impactful bass. The driver’s low total Q (Qts) of 0.41, combined with a sensitivity of 91 dB (1m/2.83V), allows for efficient power handling and tight, articulate response. A copper voice coil wound on a high-temperature former, with an inductance (Le) of just 0.49 mH, further enhances transient accuracy. The 8-inch nominal diameter (203.2mm) requires a cutout of 184mm, with six mounting holes for secure installation. This woofer is an outstanding choice for those seeking reference-level performance in a compact, well-engineered package.
