Going by a few comments on AVS the wireless is a bit of a hit and miss, some love it and some have issues
From wingnut4772:
"I have the ULS-15 Quad Drive and I like my subs. The wireless is a mixed bag. At first I liked the versatility of it but I was getting too much interference with my Bluetooth PS3, my wireless network, Squeezebox etc. I decided just to hook them up the old fashioned way and they sound great. If I were to put them in a custom room I would not use wireless but would run cables to their positions."
Austinjerry:
"While wireless works fine for many people, others (myself included) have had issues with wireless interference from other devices, including cordless telephones"
