Well for one I'm not going to run cables everywhere and the other solutions have their faults: wireless satellite lag sound, and still need a power cable; battery operated satellites require constant maintenance.
Yea, unfortunately, my old 5.1 surround system of my bachelor days fails the “wife test.” Currently, to get all the channels the sound mixers give you, you need 6 ugly black boxes with speakers in them spread around your living room and another big black box receiver. And all the speaker wire everywhere. Yuck! Even if you hide the wires in the wall and use ceiling mounted speakers it’s still intrusive and ugly.
