Buy a cable switch box and use both => you can switch musicicans in and out of the room at will!
However, move quickly, as this new speaker cable property (in room/out of room) is soon to be patented by Monster Cable. Once this happens then everyone will be aware that said properties are real and exist and you may be limited in choice to licensed cable manufacturers. (As you may be aware, Monster have issued a cease and desist "letter" to Blue Jeans for "design infringement" on certain cable connectors.)
FYI: The USPTO has also granted a patent for an "anti-gravity spaceship". You may want to get into IP Law as you can probably have a lot of amusement and make money too!
