The Dayton Audio CE78PF-4 Full-range Woofer is a remarkably versatile broadband driver engineered to deliver clear, full-frequency audio from exceptionally compact enclosures. As a dedicated full-range subwoofer, it eliminates the need for separate tweeters in space-constrained designs, making it an ideal choice for portable Bluetooth speakers, desktop monitors, and miniature sound systems where every millimetre counts.

This driver excels in small sealed or ported cabinets, offering a total Q factor (Qts) of 0.99 that suits both infinite baffle and bass reflex alignments. With a nominal diameter of 76.2 mm and a mounting depth of just 42.1 mm, it fits neatly into tight spaces while providing a maximum linear excursion (Xmax) of 1.4 mm and a displacement volume (Vd) of 4.2. The 85 dB SPL sensitivity at 1 metre with 2.83V ensures efficient power handling, while the low voice coil inductance (Le) of 0.17 mH contributes to extended high-frequency response. The 3.7 ohm DC resistance (Re) and electromagnetic Q (Qes) of 1.34 work together with the mechanical Q (Qms) of 3.9 to produce a balanced, natural sound.

Whether you are upgrading a portable radio or designing a custom miniature speaker, the CE78PF-4 delivers reliable, full-range performance in a compact, easy-to-mount package.
