The Yamaha P7000S may not be able to power a subwoofer correctly because the signal level from the receiver is too low. The Yamaha Z11 receiver outputs 2.0V from the subwoofer outputs, which may not be sufficient to drive the P7000S properly. A user solved this issue by using a Samson S-convert, which likely boosted the signal level to match the amplifier's input sensitivity.
