LFM-1 is used with KEF 107s. Because I wanted my 990-7700 to run balanced I could not interpose the KEF KUBE (KEF' bass EQ/Mgmt). I guessed that the LFM-1 sub might make the difference, negating the need for the KUBE. Got lucky. To me it sounds like I don't need the (unbalanced) KUBE.

I would love any feedback from anyone using 107s and LFM.
