My situation would best be solved by a wireless subwoofer but I'm wondering what the specs are for the wireless subwoofer kit included in the ULS15. Using this unit am I going to experience any noticeable delay in the signal? What is the frequency this works at? Am I going to lose any of the sub 20hz freqs for home theater application? I have seen where people have complained that in music there is a delay that throws the song off (they were not complaining about your unit, but another one). Will that be an issue? Does the receiver auto setup hear the time lag and apply a delay to make up for it? How reliable is the signal transfer?
