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.

Have you tried placing a speaker at the seating position, playing a bass tune and crawling around the normal speaker placement area? Wherever the bass is strongest is where you should place your speakers -- approximately.

You mentioned that your room is sound optimised, so the solution must be in speaker (and seat) placement!

 

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.
