Wireless kit for Subwoofers?

Any recommendations for a wireless kit for Subs?   In my soon-to-be finished remodeled home, I will have to use wireless to get to where I think the subwoofers would work well (and look good to the wife, very important!).

I've currently got a Krell K300i Integrated driving my Rhythmix E15HP2 subs.

What do you recommend?  I know I can hear differences in subwoofer cables and I'm sure there will be differences when using wireless - but any typical losses or things to listen for?

Thank you.
