Thank you very much for the post! I appreciate it, and am very glad that the Guide was helpful to you. I hope that what I wrote about trim levels wasn't too confusing. Section VI does explain how the gain/trim thinking on the Audyssey thread, and elsewhere, has evolved since the Audyssey FAQ was originally written. Keeping trim levels negative is a good idea with any make of AVR's, and not just those that use Audyssey.Took me two days, but I made it to the end of the article! Excellent work, incredibly comprehensive. Sure there is a lot of repeat information, but I understand why. Should be required reading for anyone interested in learning about subwoofers, all in one place. Been enjoying my Rythmik F12G for 10 years now, perfect for a small apartment, with the purchase of a new Denon 3500 AVR, I wanted to make sure I relearned all that I forgot, so I could choose the the right settings before running the latest Audyssey XT32. Your immense research and article was great in confirming what I’m doing here. Though I will say I’m still a bit confused about The Audyssey trim level debate between your more updated information versus the now older Audyssey setup thread which I reread as well. With my gain control knob at about 1:00 clock on the dial, I get the same results I did 10 years ago, “-3.5 dB”. Living in a small apartment does not allow me to even consider boosting my subwoofer manually, though I wish at times I could. Music formats are so all over the place, my sub can sound too intense or too tame depending on source material. I like that I’ve learned how to set it up for proper movie REFERENCE playback, and from there, I just use some of the new Denon AVR tricks to adjust a bit for music sources.
Thanks again, you have done a lot of work which should be acknowledged!
The bottom line, in your case, is that if you are getting a subwoofer trim setting of -3.5, you should be just fine. The -5 recommendation is just a guideline, and not a hard threshold that can't be crossed. But, if you were ever in a position to add subwoofer boost, it would be a good idea to use the gain control on your sub to do it. Or, you could always calibrate with your sub gain at 2:00, and start with a lower trim level, if you ever wanted to be able to add more subwoofer boost with your AVR remote.
