Ferrite Core Speaker Cable

We believe that this inductance reduces the natural resonances in a cable which we believe can become audible through secondary effects.

Ferrite core speaker cable.

The reason that ferrites can improve the performance of speaker cables lies in their ability to add inductance and loss to the cable. As stupid as it may sound i was wondering if a high frequency trap such as a ferrite core would distort the quality of the signal. The most likely position for a current maxima for all frequencies is near a chassis bulkhead or other electromagnetic boundary. Large opening allows several passes through center without taking connectors off.

The cable s already run and i didn t think of shielded cable until two seconds ago. I experimented with just 1 wire running through the core then 1 loop 2 wires then 2 loops and finally reduced the interference to a level i can t hear when i put 3 loops through the core. I put the ferrite core on the main speaker out wire that goes from the computer to the bass speaker where the 2 1 surround system then splits off to. This video just hits a generic use at a high level.

The ferrite cores should be installed on one wire not across both wires. Ferrite products for rf chokes baluns and rfi mitigation useful baluns and chokes for coax.

The speaker wires however do not.

Often a stack of several of these are needed to achieve target impedance. Beads provide the most suppression at vhf and uhf current maxima as in standing waves.
