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.

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 

I am an advocate for going sans subs. My room is no where as nice as @ronboco however my QLN Sonora's work well in my treated room with my X200, for now....

Subs in a system is unfortunately not a fashion statement. Going sans sub might look chic but might sound anemic. It’s about frequency response at the listening position and your room will have a lot to say about that. Your dealer will most likely take some measurements and will give you his verdict. But you probably already know the answer. Two subs might be all you need. Good luck in your journey. It’s going to be fun. 

Thank you everyone for the responses. I’ve learned so much here in the time I’ve been on agon. It’s a really great forum. 
 

Happy listening!
