Re: Measurement Help


Okay, now we can address some of your questions.

I posted the Logarithmic graph. As far as the bass traps go I intend to put to bass traps in my front corners of my room. I am curious if this is going to be enough to help.
The traps (if done right, and if there are enough of them) reduce the long low frequency decay times via absorption. They won’t necessarily smooth response, or reduce decay times for the entire low frequency range, but they do help with nulls, I believe.

I also was thinking of getting a BFD to help also.
From what I have read this will not help my voids on the graph correct? It will just help the tame the peaks, from what I understand. Please correct me if I am wrong.
The BFD can help with both. The only thing it can’t address is nulls (don’t mistake every low-point in response as a null).

I messed with the phase a bit and ran test. I am using 2 subs. First I tried shutting one sub off and played with the phase.Then I ran both subs same phase.Finally I tried both subs oposite phase.I got the best response with running them opposite.(one 0 and one 180). On this setting I was able to correct some of the problems at the 35hz region as well as the 50hz to 70hz region.
What’s the story on your subs? Ideally, they should be matching and co-located. Depending on the room, separate location is doable, but it is much more difficult to get optimal results
