Subs and room nodes

Hi everyone. I have heard so much about how multiple subs cancel out room nodes and I am a believer. I would like to learn more about how this happens. Let’s say your sub crossover is set at 80hz but the room node is at a higher frequency. If the sub doesn’t come in until 80 hz and lower how is it able to cancel the node? This is in regards to my new 2 channel dedicated room that I will be adding to my systems page soon. Thanks.

You might find useful information here on the "subwoofer crawl".  It is quite effective, especially when combined with REW and a calibrated microphone to fine tune levels and phase delay after placement.

Thanks for the tips. I’ve heard the crawl works well. I have never used REW but I do have a U Mic. I’ll check out those links as well.

Hi Ron

Congrats on the new room. How many subs do you presently have?

Hi spenav 

Thank you! 

As of right now I have no subs in the listening room. My dealer is coming next Friday to do a master set and if subs are needed (I’m assuming right now they will be needed) I will rob 2 REL S510s from our HT upstairs to try out.

I am hoping that they aren’t needed so I can get the full potential out of my Rockport Avior ii speakers
