• • Unique Patented Design
  • 113 dB sensitivity 1 W / 1 m
  • 1.9 kHz Crossover
  • Very small Size and low Weight
  • 25.4 mm Voice Coil

  BMS 4524 is an ultra compact 1" professional compression driver that delivers excellent sonic quality. The unique BMS annular diaphragm achieves very high sensitivity and linear frequency response up to 20 kHz. The sound of the BMS4524 has an exceptional dynamic range and produces even the most complex music signals with depth and definition.

  The BMS 4524 - 1" compression driver is designed for a wide variety of applications including high fidelity audio, small to medium high quality professional reinforcement systems and studio monitors. The BMS 4524 offers all the benefits of the patented BMS compression driver design, but at much reduced cost.

Driver 140WRMS, 108dB, 500-18.000 Hz

2" high frequency compression driver. The particular mylar/titanium
diaphragm using a 3" edgewound flat aluminium wire voice coil and a
optimized high energy ceramic magnet assembly using a copper shorting
ring assembly produce smooth response and excellent sonic properties .
