Measurements Maximum length of wire for outdoor speakers - B&W AM-1s
I am planning on running some speaker wire for outdoor speakers. I already had the conduit installed and it terminates at my shed, from my shed have another conduit that runs to the house. My plan is to have the speaker wire run all the way back to my house and basement to the location of audio and networking rack via the shed. That would put the longest run at ~200 feet and the shortest at 110 feet. In all there will be four AM-1s each at 110, 110, 170 and 200 feet and an OSD audio Forza sub that will be 110 feet from the network rack in my basement. I could just terminate at the shed that would cut about 80 feet but the shed has a few issues mostly that it is not a conditioned space and i live in the north east with hot summers and cold winters and i would prefer all my equipment in one location, but the shed does have electricity (dedicated subpanel) and internet connectivity via a cat6 cable. The speakers will be powered by one, maybe two, sonos amps and the sub by an OSD SMP-200 amp.
My tl;dr question is: given the shortest run of 110 feet and longest at 200 feet should i terminate the speaker wire at the basement, or save 80 feet and terminate at my unconditioned shed?
