I have a nice receiver that works well with my wired speakers in the family room but my house is not wired for speakers in each room. I would like to place Bluetooth speakers in several rooms and connect them back to my receiver. I am familiar with the Miccus Home RTX but is appears that you can only speaker at a time. What I want to do is pair 4-6 speakers so they all play at the same time. Anyone know of such a device?
