Moteur à compression BMS 4590P (avec filtre passif)
[4590P-16+16] Avis/Critiques Features :
- Extended bandwith (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 dynamic and extremely low distortion
- Perfect time alignment without the problems of multi-source interference
La compression BMS 4590P est la même que la 4590 mais avec un crossover. Courbe de réponse avec le filtre en bas de page...
ATTENTION: Le moteur de compression BMS 4590P est disponible uniquement en version 2 x 8ohms !
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 1300 W peak.
The ultra light annular diaphragm for the high range offers exceptional transient response with very high efficiency from 6 to 22 kHz.
