    Looking for a SIMPLE 7.1 surround sound processor

    Symmetrically placed subs not measuring the same?

    Is one of your room dimensions 3.06m ? that equates to 1/4 wavelength which would be a room mode where one sub is cancelling the other at 28Hz, switch the sub phases and you may find the swing the opposite way round. No easy solution, but improving the deep bass absorption would help, though...
