SPK50-15-4N28PUN

RYD SPK50-15-4N28PUN is a φ52×28.3mm full-range loudspeaker engineered for demanding automotive and industrial environments. Key parameters: 5W rated (10W maximum) input, 4Ω impedance, 160Hz resonance, Fo~20kHz range, 83±3dB output at 1m/1W, total harmonic distortion within 5% at 1kHz, and a -40°C to +95°C operating range at 60g weight. This temperature window makes it suitable for positions exposed to engine heat, outdoor cabinets and unconditioned equipment housings, working well as an automotive warning speaker, industrial voice prompt device and alarm sound output where reliability matters more than size. Manufactured under the RYD ISO9001 quality system with RoHS compliant materials. Customization available: sensitivity, impedance, connection style and waterproof or dustproof grade can be tailored to your installation, and volume programs may include new development.
