I had tried some of the cheaper transmitters for my subwoofer, and they didn't work. There would be a loud hum or constant hiss, as in a ground loop, and I was about to give up on the whole technology and pull a cable when I came across the SVS. Super easy to install (plug and play), and very small. My sub is 28' away from the system, with a couple of lounge chairs on the way. It works flawlessly (at least for now). Pricy but worth it.
