BMS 4591 2" MIdrange COMPRESSION DRIVER!! SPECIAL PRICING!
BRAND NEW, UNOPENED
- Extended bandwidth (300 - 9000 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.
