I'm looking to finish upgrading my home cinema setup, what is needed to complete my setup is the rear surround speakers. Looking for small discreet rears as Im thinking of 7.1 setup. I currently have:- Denon 3803 Amp(doing amplification and video switch duties) JM LABS Chorus 726S Front speakers JM LABS Chorus CC700S Centre MJ Acoustics Ref 100 sub Rears speaker at the moment are Mission 750LEs on stands. What Im interested in is whether a 7.1 setup would be a good idea, thinking of :- Two pairs of M&K K5s or a pair ok K4s and a pair ok K5 or two pairs of K4s. Or any other recommendations, Are there any issues with running tri and dipole speakers or should I just buy one set of K4s. I've demo'ed a very similar setup to mine with K4's when a purchased the fronts. I will see if I can demo it again just worried as the K4/5 speaker are so little and will they cope with the front setup I have.
