BMS 4590 2" Coaxial Compression Driver, 3,5" + 1,75" VC, 150 W + 80 W AES, 118 dB 16 Ohm

£279.48

Quantity:

BMS 4590 - 2" Coaxial Driver 150 W 80 W 16 Ohms

Features:

  • Extended bandwidth (300 - 22000 Hz)
  • Point source sound reproduction
  • Excellent phase coherence
  • With two subsystems in one, each driver covers a smaller frequency range for increased power handling, high dynamics and extremely low distortion
  • Perfect time alignment without problems of multi-source interference
  • 16 Ohm

In a conventional full range compression driver the phase plug must be located extremely close to the diaphragm, excursion of the diaphragm is limited and middle frequency perfomance is compromised. A typical 2" dome compression driver has a limited high frequency response. Above 8 kHz the dome diaphragm breaks up causing resonance and harsh metallic sound.

The BMS annular midrange diaphragm covers the frequency range between 400 and 7000 Hz with a smooth linear response. The large diaphragm excursion of max. +/- 0.8 mm results in high output and increases power handling up to 1300 W peak. The ultra light annular diaphragm for the high range offers exceptional transient response with very high efficiency between 6 and 22 kHz.
