I was unable to post on "The Klipsch Joint" Discus forum, so I will try here.
I plan to buy a Yamaha Aventage RX-A2070 9.2 channel AV receiver. It is rated at 140 watts per channel into 8 ohms (20-20,000 Hz) at 0.06% THD, with 2 channels driven. Maximum effective power is: 220 w/channel (1 channel driven). Dynamic power: Front L/R (8/6/4/2 Ω) ...........165/210/285/405 W. Will this receiver have enough power to drive the following Klipsch speaker setup?: RP-250F tower speakers (two); RP-450C center speaker (one); RP-250S surround speakers (two); RP-140SA Dolby Atmos speakers (four). Room size is 20ft wide x 20ft long. One wall is 10ft high and the other three are 16 ft high. Ceiling is angled and vaulted. Please advise. Thank you.
