How does this graph look after BFD?

Hi,

I'm new to the world of equalizing and BFD. I've MFW-15 subwoofer xover at 80 hz. I did the measurements manually using Excel and RS meter + CD test tones. The graph shows the measurements before and after equalizing with BFD. Is the dip at around 100 hz a normal thing? Thanks for looking at it and sharing your thoughts on it.

Regards.

Looks quite good.

Any peaks or dips after the crossover can be ignored until you add the mains and do a new measure. Then the phase control of the sub is used to get the best transition around the crossover.

I'm moving this to the REW section

Thanks Brucek. I'll do the measurement again with the mains, when I get the chance and will see how it looks.

Regards.
