Here is my final low end response! It consists of 2 seperate 12" band-pass boxes, that are EQ'd using a FBQ2496.

The first image has 1/3 octive filtering and the other has no filtering.

any comments?

Not much to say other than the response is really good.

Can we see the waterfall (using the same scaling)?

Here is the waterfall. I don't fully understand it!

Here is a better waterfall with proper graph settings.

Just out of curiosity ...Can you post the graph with EQ'ing???

Looks very good. You do have some ringing out at very low frequency <20Hz, but I don't think it will cause much trouble...

Salvasal

Here is my original sweep with no EQ'ing (Green trace) the blue trace is the PEQ filters i applied to get the traces from above.

Is that what were interested in seeing?

That waterfall, and the frequency response, look wonderful. Well done!

Thank you, that's what I wanted to see.

I will work on my sub response this weekend and I wanted to see the difference between graphs ... in your case the results are excellent

Are you boosting 8-13db between 15-25hz? Looks like about 13db at 20hz. That's a lot of boost.
