Results, SVS post Behringer

[moreira85]

Here are the results of the FR after adding the Behringer.
The blue line is the sub without BFD, the pink line is after I added the Behringer. I may make a few more adjustments, wanted to get your thoughts on this response. looks very good from 16hz to 50hz, any thoughts on the decible drop between 50 to 80hz? Is that normal? this test was done with the sub only, no mains.

Move the mic and I bet that will change that dip at 63Hz. Is one of the room dimensions 18'-7" or a multiple of it? If you were in a place where that mode's (standing wave) energy was at a minimum or you had two reflections meeting there, destructive interference (phase cancellation) will cause this.

I can't remember, is your sub in a corner? It could be that you are getting an extra boost down low in the corner.

Overall, your response looks pretty good.

yes the sub is in the right corner and I think the response looks quite good. I will post how it looks with the sub and mains later.
