•Perfect acoustical coupling
•Extreme high efficiency
•Exceptionally high power handling of 400 W (AES)
•Provides 6 dB more sound pressure than a comparable single voice coil driver
•Ultra low distortion
•Specially designed for extreme high output applications
•Ultra light weight and small size
•2x 4 or 2x 8 Ohm
•Ultra low distortion
•Neodymium magnet assembly

The BMS 4599ND dual diaphragm driver incorporates two identical 3.5” concentric annular ring diaphragms, connected to a common 2” throat, providing extremely high acoustical output.

The patented design of the BMS 4599ND is a result of extensive dedicated research and development, providing dramatic improvement in efficiency, power handling, dynamic response and clarity. In fact the double voice coil/diaphragm assembly provides 6 dB higher maximal SPL compared to an equal single voice coil driver.

Two large annular diaphragms cover the frequency range 200 Hz to 9000 Hz with a smooth, linear response. The high diaphragm excursion of maximal +/- 0.8 mm results in high output and increased power handling up to 2600 W peak.

The unique voice coil technology employs a high purity copper wire wound inside and outside of the Kapton™ former to improve the heat dissipation, dramatically increasing the acoustic output and reliability of the driver, while minimizing the power compression. The voice coils may be driven in parallel, serial or separately for optimal amplifier loading, allowing a single channel of 4, 8, or 16 Ohm as well as double channel of 2x 4 Ohm or 2x 8 Ohm.

The use of high grade neodymium magnets provides improved performance while significantly reducing transducer weight.

APPLICATIONS:
The 4599ND has two most outstanding features:

It is the loudest audio transducer ever made
The frequency range is optimized for human voice

These capabilities make it best suited for:

Communication devices for long distance
Security systems
Emergency devices
Mass notification systems
Systems for scattering birds from airports
Marine applications
Military and police communication system
Noise cancelation systems
High End Audio Loudspeakers
