Hello every body again, I recently purchased 2 new rear speakers, the same as the front 2 ( Tannoy mercury M2). I have to set the rear 2 speakers higher than front 2 and more so on prologic (sky and tv). Still not feeling that the rear sound is clear as what expected or from what I have read from your views and magazines. Is there a setting to get the most of this from my amp (Yam A5) or would it be worth selling back 2 to get the speakers that are sold to be just rear speakers. If any one is intersested I bought the same rear on the thought of the sound being same level on all 5 speakers and thinking it would sound even better.
