I had a Pioneer HTP-072 package, which came with: Pioneer VSX-324-K-P AV receiver (released 2013) Pioneer S-22W-P passive subwoofer The other speakers The AV receiver died so I bought a Yamaha HTR-2071 AV receiver (released 2017) to replace it. However, the Pioneer subwoofer no longer works when plugged into the Yamaha AV receiver. Any ideas? Pioneer HTP-072: Product page | Operating instructions Yamaha HTR-2071: Owner's manual | Quick start guide EDIT: I was actually wrong that the subwoofer was not working. When I feel the soft part (the cone thing), it's actually vibrating but it's very quiet. This is the Yamaha HTR-2071's Setup (I've extended the relevant options): Speaker Configuration Subwoofer (set to Use) Front (set to Small) Center (set to Small) Surround (set to Small) Crossover (set to 160Hz) Subwoofer Phase (set to Normal) Extra Bass Virtual CINEMA FRONT (set to Off) Distance Level Front L (set to 0.0dB) Front R (set to 0.0dB) Center (set to -1.0dB) Surround L (set to -1.0dB) Surround R (set to -1.0dB) Subwoofer Equalizer Test Tone HDMI Sound DSP Parameter Liosync Dialogue Volume Scale (set to dB) Dynamic Range (set to Maximum) Max Volume Initial Volume ECO Function If I change Extra Bass to On and the subwoofer level to 10dB, I can hear the subwoofer a lot more but it's still quiet compared to what I could get out of the original Pioneer VSX-324-K-P AV receiver.
