I bought polk audio s55 for front, s15 for surround, s35 for center, sub woofer from polk. Onkyo for atmos speaker With lg 4k tv. 1lakh 20k . And polk sound good . I hooked up my denon avr with apple tv 4k and google chromecast 2 plus tatasky hd. They sound good together. Just need few clever tricks to hide the speaker wires
