I purchased The klipsch r 1650 c a pair. After later review i was little concerned that the power range was only 35 watts. i will be running 5.1.2 on denon avr 3500x with klipsch rfIIi's as mains and the center and rear surrounds of all the same line. Svs pb2-isd( dual 12 in powered sub). I would imagine height speakers don't require a lot of wattage? I can return those and get klipsch r 1800-cs for little more money. I gain 5 watts and a 8 info woofer instead of 6.5. would i really see a difference ?is it worth shipping it all back and getting the slightly upgraded ceiling
