Refurbished BMS 4592-8s

Assistance Audio has purchased used casings of 4592-8 mid only. We have replaced the used mid range diaphragm (3.5 inch) with a new one and affixed a new high diaphragm (1.75 inch) assembly onto the exsisting 4592mid. Making a semi used 4592. Both diaphragms are new and in working order. Main body of the driver is used.

Assistance Audio is now selling these refurbished 4592s for less then a brand new BMS 4592. Available in 8 Ohm only.

4599

BMS 4599 2" Dual Diaphragm Driver

The BMS 4599 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 4599 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 excrusion of maximal +/- 0.8 mm results in high output and increased power handling up to 2600 W peak.

Nominal impedance: 2x 8 or 2x 16 Ohm
Power capacity: 400 W (2600 W peak)
Sensitivity 1w/1m: 123 dB on a 40 x 20 waveguide
Frequency Range: 200-9000 Hz

Introducing the 4508 8" Dual Diaphragm Coaxial Planar Wave Driver

The BMS 4508ND dual diaphragm coaxial planar wave driver radiates a coherent planar wave front from a rectangular piston without internal diffraction for superior dispersion control and high fidelity sound. The driver is in fact a 2-way system emplying two concentric annular ring diaphragms. Each driver covers smaller frequency range for increased power handling, high dynamic and extremely low distortion.

The 4508ND is optimized for 0 to 15 degrees vertical dispertion and allows a horizontal coverage up to 120 degrees depending on the waveguide used. The unique design allows perfect acoustical coupling of individual units with excellent phase coherence and perfect time alignment to create a virtually continuous line source.

Rectangular piston measures: 8"x3/4"
Power Handling: 150/80 watts
Sensitivity: 115 dB (1w/1m)
Freq Range: 300-22,000 Hz
Voice coil diameter: 3.5”/1.75”
