A modern field-coil loudspeaker model of the famous Western Electric WE 755A.

The all paper cone in its origin shape is attached to a new voice coil with symmetric grouped flexible connection wires, an extremely linear spring suspension induce uniform cone movement, the suspension treatment dampens the outer part of the cone effectively, and an all new field-coil motor ensures a consistent stimulus. 

Frequency response = 70 – 13,000 Hz
Power handling = 30 Watts
Sensitivity = 95 dB @ 1W/1m
Diaphragm = driven by a 50 mm diameter voice coil on treated paper former
Flux density = variable
Net weight = 6.3 kG
Diameter = 260 mm (square)
Mounting hole diameter = 200 mm 4 bolt mounting square
Voice coil impedance = 8 Ohms
Resonance frequency = 65 Hz
