Waiting on a black 3806 and 3910. Got B&W MT-30 and trying to set speakers up. I did originally have the sub on the left but felt it was a bit exposed so I moved it behind the TV unit. Will it be ok there or will it cause any probs? eg due to radiator being close + other equipments proximity. I also heard that a sub is worst placed in the corner of a room. Is this true? Cheers in advance. PS: Feckin Sky man made the sky+ cable too short!
