Hey all, noob here but I've looked around the forums quite a bit and wanted to clarify the info I've read. I've got a Yamaha Aventage RX-A680 along with a 5.1 set up of Yamaha entry-level satellites and an 100W 8" ported sub. Not the greatest, but can actually provide a nice clear sound with the upgraded AVR in my small room. Anyways, I am wanting to maximize the bass I can get out of this small sub by using more gain and less juice from the receiver. I recently moved the sub after realizing the port was on the right side and not the back, so it was hitting a wall and getting nasty reflections at near-reference levels. After doing the crawl and finding ideal placement that still ran a strong WAF, I ran YPAO and with the gain knob on the sub around 2:00 it set the sub at -5db (+/- 10db total) in the Level screen with the other speakers., which seemed like a good starting point This receiver has another menu with a separate subwoofer trim of +/- 6db for making on the fly adjustments. Ideally, would it be better to turn the gain on the sub up and run the trim lower without adjusting the overall volume level? Or is going positive on the subwoofer trim ok as long as the overall volume stays at a net 0db or less (say I chose to add up to 5db of extra trim without affecting gain, resulting in a net 0db level)? I want to maximize gain and minimize distortion and just wasn't sure of the overall relationship between the speaker volume level that YPAO sets and the separate subwoofer trim (Yamaha's documentation of subwoofer trim reeks of marketing BS). Thanks for any and all help!
