Question Is 14 gauge always necessary for over 50ft

[LudinK]

I’m planning on wiring some speakers up in my warehouse. It is a long warehouse and the receiver will be on one end so one of the wires will have to be over 200ft. I’ve been looking around trying to find the most optimal wires for the setup. One website stated that if the wire is intended to be longer than 50 feet, 14 gauge wire should be used. I’m planning on setting up 4 bookshelf speakers equally distanced apart. 2 are a pair of PSB and one is a paradigm atom (both the older models). Is 14 gauge wire necessary for good Audio quality in this setup??

Speaker runs that long are typically handled by 70V speakers. 14GA wire has 0.5 ohms 16GA is about 0.8 ohms and 18GA is about 1.27 ohms.
Audio quality and warehouse are not usually associated. A warehouse would also typically want outdoor rated speakers since warehouses are not climate controlled.
