BMS 4590 Treiber 2 Zoll 8 Ohm Product Details
Driver 2" 4590 8 Ohm
2" High Power Coaxial Compression Driver á Patented Design
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 performance is compromised.
A typical 2" dome compression driver has a limited high frequency response. Over 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 7.000 Hz with a smooth, linear response. The large diaphragm excursion of max. ±0,8 mm results in high output and increased power handling up to 1.300 W peak.
The ultra light annular diaphragm for the high range offers exceptional transient response with very high efficiency from 6 kHz to 21 kHz.
Extended bandwidth (400-21.000 Hz)
High efficiency
With two subsystems in one, each driver covers a smaller frequency range for increased power handling, high dynamic and extremely low distortion
Excellent phase coherence
Point source sound reproduction
Perfect time alignment without the problems of multi-source interference
