The Dayton Audio CE70PR-4 Full-range Woofer is a compact yet powerful broadband driver designed to deliver exceptional full-range sound in space-constrained applications. Engineered for versatility, this 70mm woofer excels in small sealed or ported enclosures, making it an ideal choice for desktop speakers, portable audio projects, and multi-driver arrays where balanced frequency response is critical. Its robust construction also suits custom installations in automotive or marine environments, offering reliable performance across diverse listening scenarios.

Technically, the CE70PR-4 features a nominal diameter of 63.5mm with a mounting depth of just 41.2mm, allowing integration into slim profiles. It achieves a sensitivity of 85 dB SPL at 1m/2.83V and a total Q factor (Qts) of 0.63, ensuring smooth bass extension and controlled transient response. The 4mm linear excursion (Xmax) and displacement volume (Vd) of 9.84 contribute to impressive low-frequency output for its size. With a DC resistance (Re) of 3.13 ohms and voice coil inductance (Le) of 0.31 mH, this woofer pairs efficiently with modest amplification. The 4-hole mounting pattern and 63.8mm cutout diameter simplify installation, while the broadband design eliminates the need for a separate tweeter in many applications. Ideal for DIY enthusiasts and professionals seeking compact, high-fidelity sound, the CE70PR-4 combines Dayton Audio’s engineering excellence with practical, space-saving performance.
