Well with the help of my two college age kids I was able to convince my wife that two Fortes is better than two Heresys + two subwoofers. Along with that I listened to some Chainsmokers and Sylvan Esso last night when nobody was home to distract me and have decided I have enough subsonic bass to live with....at least for the time being. So the Forte IIIs stay! They truly are wonderful sounding and well built speakers. Now to add the MC2105 and see if everything improves!
Thanks to all of you for your advice and insight. I look forward to many years as a happy Klipsch owner now.
