My Linn centre speaker has blown.Until i decide on a replacement i'm going to use a Mordaunt Short 905i,i found tucked away in a cupboard.There are 4 connections on the back,2 negative & 2 positive.For some reason i can't remember i must have thought about bi wiring it.I have the 2 negs joined with a small piece of speaker cable & the 2 positives ,the same.I only have negative & positive cable from the amp & have no intention of bi wiring anything,I can't remember how this works,so do i leave the connectors on the back of the MS speaker connected with the bits of cable or do i remove the bits of cable & just connect the cable from the amp to 1 of the negatives 1 of the positives on the MS.
