The speaker-units are adjustable to the characteristics of your power-amplifier. Since

these differ strongly you have to check the best switch position for your specific
setup.
These are the key-rules for the adjustment:

High-frequency unit
Switch (4) in position VD-N

•

This is recommended for transistor power amps with damping-factor falling with

frequency

Switch (4) in position VD-H (Standard)

•

Recommended for transistor power amps with constant damping factor

Low-frequency unit
Switch (4) in position VD-N

•

This is recommended for fast transistor power amps.

Switch (4) in position VD-H (Standard)

•

Recommended for transistor amps with strongly load- dependent output-power
