DMS4008-01

RYD DMS4008-01 is a φ40×5.1mm micro speaker with exceptionally high output: 102±3dB at 1W/0.1m (92±3dB at 0.1W/0.1m). Rated input is 0.5W (0.8W max) at 8Ω, resonance 600Hz, effective range Fo~6kHz, distortion within 5%, operating from -20°C to +60°C. This efficiency makes it ideal where audibility is critical at limited amplifier power: industrial alarms, medical alert devices, smart home hubs and public indication equipment. Internal-magnet design with φ12.5×1.5mm neodymium magnet. Manufactured under the RYD ISO9001 quality system with RoHS compliant materials. Customization available: sensitivity, impedance, connection style and waterproof or dustproof level; volume programs may include new development. Contact RYD to confirm SPL targets.
