I'm currently using Kef Ref 2.2's with a Celestion A4C, A1 in 5.1 and am very happy with the sound. For my much larger new HT I've got some A2's which I was intending to use as sides. But would it be better to use the A1's for the sides and A2's for the rears? I almost always use Logic7 on my MC1. In addition I've got some KEF TDM34DS's that sound brilliant and are less than a year old. I stopped using them because of positioning restrictions in my current room. Would they make a better side speaker? My apprehension in using them in the new room is that only a certain number of seats could be in the null position. There is over 14ft from my front row to back row of seating. Should I sell the TDMs? or the A1s? I'm leaning towards selling the TDMs. Mark.
