Dayton Audio DCS165-4 6-1/2" Classic Subwoofer

The Dayton Audio DCS165-4 Subwoofer delivers exceptional low-frequency performance for demanding audio applications. Engineered for enthusiasts and professionals alike, this high-excursion driver brings depth and precision to any sound system where accurate bass reproduction is essential.

Ideal for use in custom speaker builds, home theatre setups, or car audio installations, this subwoofer excels in sealed and ported enclosures. Its carefully optimised parameters make it suitable for both music and film soundtracks, providing tight, controlled bass that enhances the listening experience without distortion.

At the heart of the DCS165-4 lies a paper and Kevlar cone, chosen for its rigidity and damping properties. This material combination ensures clean, articulate bass while minimising cone breakup. The copper voice coil, with a DC resistance of 3.4 ohms, offers efficient power handling. Key technical specifications include a total Q factor (Qts) of 0.34, indicating excellent transient response, and a maximum linear excursion (Xmax) of 6 mm, enabling significant air displacement. The 74.8 cm³ displacement volume (Vd) further supports deep bass output. With a sensitivity of 87.4 dB SPL at 1 metre with 2.83V input, this driver pairs well with moderate amplification.

Robustly constructed with an 8-hole mounting pattern and a 142.7 mm cut-out diameter, the DCS165-4 is straightforward to integrate into existing designs. Its 82.6 mm mounting depth allows for flexible enclosure planning. Whether you are upgrading a current system or building from scratch, this subwoofer offers reliable, high-quality performance at an accessible price point.
