While the speakers themselves are 8 ohms, that 70 volt transformer allows them to be driven by Public Address type amplifers that output a standard 70 volt signal. This is quite common for PA use when many, many speakers are being driven by one amplifier.

so this should be set what voltage on that dial if im hooking them up to a stereo receiver,
