Room nodes
I have been "fighting"an aggravating resonance in my stereo system for a
long time. I tried a sweep with a signal generator today and it appears to be around 180 hz. This makes sense because my room dimensions suggest a number of nodes at that frequency (22' X 30' with an 18' cathedral ceiling). I tried suppressing it by setting the 120 hz slider on my equalizer at -12. This helped a lot but I would like to suppress the exact frequency. I know this would require either a parametric or 1/3 octave equalizer. Any suggestions? ---MIKE--- |

Were you the one using two subs?

No - FOUR subs! Two in corners and two along walls. The resonance is a
room condition (I can hear it with the subs off). ---MIKE--- |

My one Sub capable of being heard 200 feet (my opposite house )- if i were to push it to the max. Right now I am only using a small fraction of its max. Anyhow here's a link http://www.mhsoft.nl/Helmholtzabsorber.asp hopefully, that will help you. Cheers. |

... Hmmmm. Care to be more specific? What is your sub? Why? you think it can't be heard that far? Even my car 10 inch Rockford Fosgate Punch can be heard quite a distant if I push it to the max. But not up to 2 miles as this gentleman http://www.cardomain.com/reviews/lis...sku=ROCRFD2210 is claiming but at least 120 feet. My Sub is Boston Acoustics not a true High End but pretty much good for the job. cheers. |
