CMS-25148N is a compact speaker designed for audio applications requiring high sound pressure level output in a small form factor. It features a nominal impedance of 8 O, maximum input power of 1.5 W, and delivers 92 dB SPL at 1 W measured at 0.1 m, with a resonant frequency of 1050 Hz. The speaker employs a Nd-Fe-B magnet, cloth cone material, and PBT housing, with dimensions of 25.0 × 14.0 × 5.2 mm and a weight of 2.4 g. It operates reliably across a temperature range of -20°C to +55°C and exhibits a frequency response from its resonant frequency to 20 kHz with maximum distortion of 5% at 2 kHz and 1 W. This speaker is well-suited for portable electronics, alarm systems, notification devices, and other compact audio applications where space and power efficiency are critical.
