Dayton Audio CE20-14M-8 3/4" x 1/2" Micro Speaker

The Dayton Audio CE20-14M-8 Micro Speaker is a compact yet capable audio component designed to deliver clear, reliable sound in the most space-constrained applications. Measuring just 19.8 × 14 mm with a nominal diameter of 25.4 mm and a depth of only 3.6 mm, this micro speaker is ideal for portable electronics, small enclosures, and custom audio projects where size is at a premium. Whether you are building a miniature Bluetooth speaker, upgrading a handheld device, or integrating sound into a compact IoT product, this driver offers a practical solution without compromising on audio quality.

Technically, the CE20-14M-8 features a polypropylene/Mylar cone diaphragm paired with a neodymium magnet, ensuring efficient performance and durability. Its impedance is 8 ohms with a DC resistance of 7.03 ohms, while the sensitivity is rated at 77 dB SPL at 1 metre with 2.83V input. The total Q factor (Qts) of 1.46, along with a mechanical Q (Qms) of 2.21 and electrical Q (Qes) of 19.9, indicates a design suited for small sealed enclosures. With a maximum linear excursion (Xmax) of just 0.1 mm and a voice coil inductance (Le) of 0.36 mH, this speaker is optimised for clear midrange and high-frequency reproduction in compact spaces. The cut-out diameter is 16.3 mm, making installation straightforward. As part of the Dayton Audio CE series, this micro speaker combines precision engineering with affordability, offering a reliable choice for your next compact audio project.
