Hello Ethan,
i just caught part of the HT Geeks episode where you were interviewed by Scott Wilkinson back in January. I was at work so I wasn't able to get through the whole episode or pay full attention for that matter, but I would love to know more about your SVS sub setting.
You stated that you have the SVS set to -3.5db and tuned to 18hz. Could you elaborate on that please? Are you referring to a parametric EQ setting? Assuming that's what you were referring to, I adjusted the parametric EQ on my Mirage Nano at 31.8hz to have a 5.000 gain and Holy Hanna, it had an Earth shattering impact. It sounded great without adding to the overly boomy base I am already dealing with. My wife commented that she thinks I cracked the foundation of the house. I have a Mirage SB8 sub as well, that I haven't adjusted yet. I'd live to get hold of a couple of SVS subs someday. I haven't actually heard one yet, but have only heard good things about them.
I still need to implement bass traps to tame the overall boomyness in my room. Can't wait to hear the results when I get time to work on that project.

Those are two different things about my SVS sub. This sub has three ports that can be "stuffed" with the provided foam plugs in various arrangements to vary the -3 dB point. When tuned to the lowest 16 Hz setting the overall bass level is a bit lower than when it's tuned to higher cut-off frequencies. So I chose 18 Hz, the middle tuning available, to get both a high output and an adequately low frequency.
The other "tuning" I did was adjusting the built-in one-band cut-only parametric EQ. I set that for 44 Hz and about -3 dB to help tame a peak in the response due to the room's length mode. I can't speak highly enough about SVS subs. I imagine some other brands are good too! But I know for sure that SVS is great, and I can't recall ever hearing someone say they were disappointed with theirs.

Thanks for the clarification Ethan. I totally forgot about bass plugs. I was wondering how you got down to tuning to 18hz. The parametric EQ on my Yamaha RX-A2020 only goes down to 31.3hz. I think I said 31.8 in error. My Mirage Nano sub has one port, but I have never used a plug. I hope to get back to your interview soon to finish it off and pick up some of the things I missed the first time around. Nice setup btw.
Thanks again- Chris

I just checked the SVS manual again, and the "extension" frequencies with ports blocked are 16 Hz and 20 Hz. So mine is set for -3 dB at 20 Hz. But it still has substantial output well below 20Hz. Not that I'm bragging! Did you see the tour video I made of my living room setup? www.youtube.com/watch?v=qu32oisgIq0

Thanks for the link, I had not seen your video yet, just pics of your room from the HT Geeks interview. I believe I saw a pic of the Yamaha receiver I have show up when you were showing your gear. I think the panels look great as is, they look classy. That SVS sub is a monster!
Your video helped me understand a little bit better what a diffuser is. I did not realize that an absorber may deaden the room. This rookie has a lot to learn.

Thank you for the links Ethan. I enjoyed reading your article on comb filters and I agree with your stance completely. It's amazing that I can turn my head or adjust my position even slightly and hear something different. I'm looking forward to learning more about acoustical treatments.
