Dayton Audio CE38M-8 1-1/2" Mini Speaker

The Dayton Audio CE38M-8 is a compact 1.5-inch mini speaker designed to deliver clear, reliable audio performance in space-constrained applications. This micro speaker is ideal for DIY electronics projects, portable audio devices, alarm systems, and small-scale sound installations where a full-sized driver would be impractical. Its modest footprint makes it particularly well-suited for hobbyist builds, model-making, and custom audio enclosures where efficiency and size are paramount.

Technically, the CE38M-8 features a neodymium magnet and a polypropylene/Mylar composite cone, which together achieve a sensitivity of 75 dB SPL at 2.83V and one metre. The 8-ohm impedance ensures compatibility with a wide range of amplifiers and audio circuits. With a total Q factor (Qts) of 1.17, this wide-bandwidth driver offers a balanced response suitable for full-range reproduction in small enclosures. The maximum linear excursion (Xmax) is 0.1 mm, and the DC resistance (Re) measures 7.72 ohms. The speaker’s cut-out diameter is 36.8 mm, with an overall depth of 41.9 mm, allowing for straightforward integration into tight spaces.

In summary, the Dayton Audio CE38M-8 mini speaker provides a practical, high-quality audio solution for projects requiring a compact yet capable driver. Its robust construction and thoughtful engineering make it a reliable choice for both novice and experienced builders.
