Hi Sarang,
Axiom has not experimented with wireless subwoofer technology, nor have I, however we did experiment with wireless speakers for outdoor use.
In a general way, as soon as you get into wireless technology, there are several major problems--noise and interference being well up at the top of the list. There are so many competing devices for wireless bandwidth that it's almost impossible to totally eliminate the problem. If you've played around with various wireless headphones, which I've done, you'll get some idea of the intrinsic problems.
I've never played with a wireless subwoofer connection to see what the current state is. Of course, you still have to connect the subwoofer to AC power, because you can't transmit amplifier power wirelessly.
Regards,
Alan
