The main purpose of a resistor in a passive speaker filter is to attenuate a speaker or to compensate for its impedance.
Below 3dB attenuation, a series resistance is sufficient, beyond which we advise you to make a mounting called voltage divider bridge.
Our resistors are manufactured in France by SETA.
They are divided into two series:
- the non-inductive 10W RWS, tolerance 5% - to use in Hi-Fi,
- the 25W RB inductive, tolerance 5% - to use in sound system.
