Dayton Audio CE140-30S-8 1" x 5" Extended Range Driver 8 Ohm

The Dayton Audio CE140-30S-8 is a compact yet remarkably capable 1" x 5" extended range driver, designed to deliver clear, full-range audio in space-constrained applications. This micro speaker is an ideal choice for designers and hobbyists seeking to integrate high-quality sound into portable Bluetooth speakers, desktop audio systems, or custom multi-channel arrays where size is at a premium. Its extended frequency response makes it particularly well-suited for near-field listening and small enclosures where a traditional woofer and tweeter combination would be impractical.

Engineered with a lightweight glass fibre cone and a powerful neodymium magnet, this driver achieves an efficient performance despite its diminutive stature. The voice coil inductance measures 0.78 mH, while the DC resistance is 7.75 ohms, ensuring stable operation with standard amplification. With a mechanical Q (Qms) of 4.64 and an electromagnetic Q (Qes) of 1.35, the total Q factor (Qts) of 2.76 indicates a well-damped response suitable for sealed or ported enclosures. The maximum linear excursion (Xmax) of 2 mm allows for respectable output levels, and the sensitivity is rated at 76 dB SPL at 1 metre with 2.83V input. Measuring just 137.2 x 38.1 mm with a cut-out diameter of 124 mm and a depth of 35.6 mm, this driver from the Dayton Audio CE series offers a compelling blend of compact dimensions and audio fidelity.
