upstairs audio speakers

[ndmarks]

I have an older audio receiver/amplifier downstairs and want to run two speakers upstairs. Is there a way to do this without running additional new speaker wires?

Never tested, but an option would be https://www.amazon.com/Wireless-Transmitter-Receiver-Subwoofers-Surround/dp/B00SJ49ZJQ I guess. Check the reviews before deciding.
