A wireless system can be achieved using Sonos. The Sonos system allows you to install a complete surroundsound system without any wires to the speakers. The base is exceptional and the sound is exceptional. It is well worth the cost and investment. The system I have installed allows me to have a full surroundsound system in the greatroom, stereo sound on the patio, stereo sound in master bedroom, stereo sound in garage, and stereo sound in guest suite. This was achieved without the installation of any speaker wires. Contact your Sonos dealer to resolve your issue.
