Hi Gene,\n \nAm I understanding this correctly -- that the miniDSP works in conjunction with HT multiple sub optimization by "working" only with the front left and right channels? Or, can the optimization somehow include the center channel? Or does optimization with the center channel only occur separately from the L & R? Does one have to purchase the miniDSP 88A (with the bass management plug-in) in order to optimize multiple subs with those front three? And if yes to the last, then what does one "give up" by not being able to use\/import REW files (into the 88)?\n \nThank you.
