Hello,

I recently upgraded my fronts and my side surrounds. I have the QS8's and they are fantastic. I have an older pair of monopole Infinity's and am always looking to make things better. Is a monopole speaker the best solution for the rears, or would I get better surround sound by going with another pair of QS8's or QS4's for the rears or just getting better monopoles like the M3? Thanks.
