Using shelf system as subwoofer

[alok_student2000]

Hi friends,

I have a Sony Gr444 system with a 'Super-woofer' line out on its rear.

which is connected to another system, supposed to be used as a sub-woofer amp.

The issue is that system is that vocals are clearly audible along with the Low frequency which is not enjoyable.

So is there way by which I can filter out the vocals from the 'super woofer' signal, before it enters to the other system so that I can only hear the bass and no vocals ?

Easy way is to use the tone controls or graphic eq in the other system to reduce the mids and highs.
Else you'll need to fit a low pass filter aka subwoofer filter. You'll get ready built boards online or local ships that sell audio related electronic components. You'll need to add batteries or a psu to run them
