This is my setup except for dual subs. I don't know your room cubic feet, but believe me, dual subs are the way to go. You might have liked dual R-112SW subs; however, you've already bought the 115 so consider another as a future upgrade. You'll never go back to a single sub. :-) We love to spend other folks' money--and even offer excuses for your significant other ("But if I buy all three, I'll save $450. Don't you want me to save us $450?"). What about rear surrounds? I'm using the older RF-82s replaced by the RP-280Fs. Of course you can use the bookshelf models, but if you have working older ones.... That will get you to 7.2. If you want to enjoy Dolby ATMOS or DTX HD Master object-based sound, you'll need height speakers. Upfiring with RP-140s models won't sound as good at using them as height speakers angled towards the floor. They don't have to be ceiling mounted. Mount them in pairs between the fronts and surrounds and surrounds and rear surrounds. That's what I've done and firing them directly without reflecting sounds much better (although it's always possible that bouncing sounds good in your room--you can always try both ways like I did). See, we've got you to 7.2.4. You'll need an 11 channel amps for this, so unless you have 11 powered amp channels, you'll need a either an 11.x avr or an add-on 2 or 3 channel amp. Then put a UHD disc in your player and prepare to duck from the carnage and mayhem flying all around and over you. The Normandy beach landing in "Saving Private Ryan" is downright scary (scarier).
