    Hello, I'm in the process of integrating my front mains (unpowered towers) into my HT system's two subwoofers - I plotted the response curves of each sub and mains separately and together and now I want to reverse the polarity of the mains and plot the effect . . . . so if I reverse the polarity of both mains and decide to permanently keep it that way, do I know have to reverse the polarity of my side surround rear sats and rear surround sats to keep all my spkrs well blended (I'm going to a 7.1 setup) - my intuition is that I don't, can someone please confirm?

    Thanks!

    Reversing the polarity of the mains (in relation to the subs) would have the effect of reducing response about a half-octave or so above and below the crossover point. If you decide to do this, then it is generally best to switch all the upper-range speakers. Otherwise the mains and surrounds are out of phase with each other.
