Summary of KEF Kube 8 MIE Subwoofer
Subwoofers are designed in a way so they can be connected to a power amplifier or AV receiver differently.

With it, one end of the RCA cable should be fixed to the KEF Kube 8 MIE, and the other output should be connected to the amplifier.

Setting up a Sub

Make sure the bass is increased if you determine the correct position of the phase switch by setting it so that bass to be boosted. If the phase of your main speaker is not the same as the one the bass may be diminished.
The next thing is a low pass filter which should be adjusted by listening to the sound and matching it with the cut-off frequency of your main speakers.
