Dayton Audio RSS390HF-4 15" Reference HF Subwoofer

The Dayton Audio Reference RSS390HF-4 is a 15-inch subwoofer engineered to deliver deep, accurate low-frequency reproduction for discerning audio enthusiasts. This driver is ideally suited for high-performance home theatre systems where cinematic impact is paramount, as well as for dedicated hi-fi stereo setups that demand precise, articulate bass. Its robust construction also makes it an excellent choice for custom loudspeaker designs where controlled, powerful low-end extension is required.

Technically, this subwoofer features an aluminium cone and a high-excursion design, enabling a maximum linear excursion (Xmax) of 14 mm and a displacement volume (Vd) of 1161.4 cm³. The copper voice coil wire, with a DC resistance of 3 ohms, ensures efficient power handling, while the inductance (Le) of 0.92 mH contributes to clean transient response. With a sensitivity of 91.2 dB SPL (1m/2.83V) and a total Q (Qts) of 0.43, it balances low-frequency extension with controlled damping. The mechanical Q (Qms) of 3.02 and electromagnetic Q (Qes) of 0.5 further refine its performance. Installation is straightforward thanks to a 355.8 mm cut-out diameter and eight mounting holes, with a mounting depth of 178 mm. This reference subwoofer is a superb choice for those seeking authoritative, distortion-free bass.
