Whole house music and multi-room systems are very popular in homes and living spaces of all shapes and sizes. There are many ways to send music throughout a home, including wired and/or wireless connections that enable control from anywhere. You can use an existing receiver as the center hub, or you can install a completely dedicated whole house music system. The amount of effort involved can range from adding a speaker switch to a receiver, do-it-yourself wired/wireless networking, or something more sophisticated that would require professional installation. However, there are pros and cons to the different methods available.
