Aperion Zona wireless speakers. In good working order. While they are a capable 2.0 system in their own right- These are an ideal (and rare) solutions to those who want wireless surround speakers for their home theatre. These of course need power cables, but no wiring to the receiver- the speakers connect wirelessly via a hub which sits behind your receiver. Add to any receiver with surround pre-outs and you’re good to go. Sound quality is quite good. Originally $400 new.
