The external crossover, consists of three constant group delay filters. A constant group delay filter, is our own proprietary design, which alters the attenuation slopes of the driver filters, to shape the phase(and doing so the GD)in such a way ,as to provide maximum GD linearity.
Using this specific filter technology to the physically time aligned horns, the Symphonia speaker present time domain performance which is near perfect, and a frequency response with a maximum deviation of +-0.5db (250Hz-20KHz).
Sensitivity : 101db
Frequency response(-3db) : 32Hz~100Khz
Weight: 170kg each
Dimensions : 930mmW X 1300mmH X 880mmD
