Electronic Crossover (1978)
The 4000 electronic crossover adds a new dimension to high quality speaker systems.
By introducing multi amplification to the system, each driver (ie woofer, tweeter etc) receives it's signal from a separate amplifier being driven over a more narrow range.
Consequently, amplifier distortion is minimised and speaker system crossover network distortion is totally eliminated.
Thus any speaker becomes cleaner and more accurate than was ever before thought possible.
Total harmonic distortion: 0.02%
Signal to noise ratio: 95dB
Frequency response: 20Hz to 20kHz
Dimensions: 19 x 3.5 x 3.5 inches
