BMS C0-axil driver unit model:4590 2" COAXIAL COMPRESSION DRIVER 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 8 or 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.
