I've just invested in a second pair of KEF TDM34 dipoles for my 6.1 system. Each pair came labelled L&R (I think so anyway, 'cos there's an L & R at the end of a number by the speaker terminals). But which driver fires which way on which speaker ? I think I remember reading on this forum that you should reverse the L&R speakers for the surround back channel. Is this correct? Does anyone have any useful info on this subject? I'd really appreciate some help. Thanks.
