A:AnswerMy only complaint with wall mounting was the lack of a template for screw layout. It is kind of a buggar to get on the wall perfectly. Careful measuring is required. I’d recommend making your own template for layout. I believe the speaker will accept either type of connection.
A:AnswerThis particular center channel is not WISA compatible. The RP-440WC is a WISA compatible center channel. The Kipsch speakers that are WISA compatible use a proprietery HD control center to power them. I'm not quite clear on how that system intergrates with your home A/V receiver.
