Dayton Audio DSA175-8 6-1/2" Designer Series Aluminum Cone Woofer

The Dayton Audio DSA175-8 6-1/2" Designer Series Aluminum Cone Woofer represents a superb choice for audiophiles and DIY enthusiasts seeking exceptional bass and midrange performance. Engineered to deliver tight, controlled low frequencies and a remarkably clear midrange, this driver is ideal for use in high-fidelity two-way or three-way speaker systems, as well as dedicated subwoofer designs in compact enclosures. Its robust construction ensures minimal distortion even at higher output levels, making it equally suited for home audio projects and professional installations where accuracy is paramount.

At the heart of this woofer lies a rigid aluminium cone, chosen for its excellent stiffness-to-weight ratio, which significantly reduces cone breakup and delivers a clean, articulate response. The technical specifications further underscore its prowess: a total Q factor (Qts) of 0.29, combined with a low electrical Q (Qes) of 0.35 and a mechanical Q (Qms) of 1.66, ensures optimal damping and transient response. With an Xmax of 5.3 mm and a displacement volume (Vd) of 67.6, the DSA175-8 produces impressive output with minimal compression. The 5.8 ohm DC resistance and 0.85 mH voice coil inductance, paired with a copper voice coil wire, contribute to efficient power handling and controlled thermal performance. Sensitivity is rated at 88.1 dB (1m/2.83V), offering a balanced blend of efficiency and dynamic capability.

This 6-1/2" driver, with a nominal diameter of 165.1 mm and a mounting depth of 80.6 mm, requires a cutout diameter of 144 mm and features five mounting holes for secure installation. Whether you are upgrading an existing design or building from scratch, the DSA175-8 delivers the precision and authority expected from Dayton Audio’s Designer Series.
