Dayton Audio RSS315HF-4 12" Reference HF Subwoofer

The Dayton Audio Reference RSS315HF-4 is a 12-inch subwoofer engineered to deliver deep, accurate low-frequency response for discerning audio enthusiasts. This high-excursion driver is ideal for use in sealed or ported enclosures within home theatre systems, high-fidelity stereo setups, or dedicated subwoofer designs where controlled, powerful bass is essential. Its robust construction ensures reliable performance even during demanding passages.

Technically, the subwoofer features an aluminium cone and a copper voice coil wound on a robust former, providing excellent heat dissipation and low distortion. With a maximum linear excursion (Xmax) of 14.3 mm and a displacement volume (Vd) of 736 cm³, it moves substantial air for impactful bass. The motor structure is optimised for high sensitivity (90.3 dB SPL at 1m/2.83V) and low DC resistance (3.1 ohms). Key parameters include a total Q (Qts) of 0.39, a mechanical Q (Qms) of 2.83, and an electrical Q (Qes) of 0.45, indicating excellent damping and control. The voice coil inductance (Le) is 0.96 mH, contributing to extended high-frequency response. With a nominal diameter of 304.8 mm, a cut-out diameter of 282 mm, and a mounting depth of 146 mm, it fits standard enclosures using eight mounting holes. This subwoofer combines precision engineering with high output capability for a truly reference-grade listening experience.
