Dayton Audio CE40-4 Full-range woofer

The Dayton Audio CE40-4 Full-range Woofer is a compact yet remarkably capable broadband driver, engineered to deliver clear, full-range audio in space-constrained designs. As part of the respected CE series, this 4-ohm woofer offers an ideal solution for applications where a single driver must cover a wide frequency spectrum without the need for a separate tweeter.

This versatile unit excels in a variety of settings, from small bookshelf speakers and multimedia systems to custom audio installations and portable Bluetooth enclosures. Its full-range nature makes it particularly suitable for projects where simplicity and efficiency are paramount, providing a cohesive soundstage in tight enclosures. Whether you are upgrading a vintage radio or building a compact desktop monitor, the CE40-4 delivers dependable performance.

Technically, the woofer features a maximum linear excursion (Xmax) of 0.7 mm, enabling controlled bass response despite its modest size. With a sensitivity of 80 dB (SPL 1m/2.83V) and a total Q factor (Qts) of 1.12, it is optimised for use in sealed or small vented boxes. The 16 mm voice coil and 3.6-ohm DC resistance (Re) ensure efficient power handling, while the low voice coil inductance (Le) of 0.06 mH contributes to extended high-frequency response. The resonance frequency (Fs) of 194 Hz and equivalent volume (Vas) of 0.064 litres further define its suitability for compact enclosures.

In summary, the Dayton Audio CE40-4 is a well-engineered broadband woofer that combines practicality with performance, making it a reliable choice for discerning audio enthusiasts seeking full-range sound from a single driver.
