Midsize Soundbox RB-52LF08K-1

The Midsize Speaker Model RB-52LF08K-1 is a soundbox speaker with dimensions of 52x52x31mm and a weight of 67g. It features a ferrite magnet sized Φ40×8.0T and has an impedance of 8 ± 15% Ohm at 1000Hz. The speaker operates at a normal power rating of 5W, with a maximum rating of 5.5W, and an FO of 200±20% Hz. It delivers a sound pressure level (SPL) of 94±3dB and covers a frequency range from F0 to 20,000Hz, maintaining distortion below 5%. The speaker passes the abnormal sound test at

6.32 volts sine wave, and the diaphragm moves forward when a positive DC is applied, marked by a red “+” terminal. It operates in temperatures ranging from -20°C to +55°C and can be stored in temperatures from -25°C to +65°C. Durability tests include a load test with white noise for 96 hours at 2.0W, a high-temperature test at +65±2°C for 96 hours, a low-temperature test at -25±2°C for 96 hours, and a humidity test at +40±2°C with 90~95% relative humidity for 96 hours.Additionally, the speaker undergoes a vibration test at a frequency of 30±15 Hz with an amplitude of 1.5 mm for 2 hours per axis, a drop test from 1 meter onto a concrete floor 19 times, and a temperature cycle test from 25°C to 65°C over 5 cycles. The minimum order quantity (MOQ) for this model is 10,000 units.
