Actually D&B saves me money. The setup/take down time is much less than with my former huge old fashioned systems. I can bring much less, draw less power and charge more with these systems. It's no Floodlight but actually sounds pretty good and gets every job done. 



my bad humour doesn't really come across well on here does it? I love the D&B smaller stuff, as you say loads of give from a little rig. I feel ya with what the client pays for.... im turning down 80% of inquiries at the moment as its just not worth missing sleep for!

I messed up with the delay compensation. There were some values in ms didnt realize it.
Now it looks like this:

And crossover starts to sound nice.
Setup:

Vocal:

Kick:


Still plenty of work left on low mid.
I am also getting to conclusions that any sort of REW measurements in the room are a total dumbness


You just need to learn to window the measurement to make it anechoic

Vocals sounding very clear Genome and impressive kick from a single 8".

A bit of testing we did the other day.

What do you mean?

I digged the old files:
https://drive.google.com/folderview?id=1KiQ_gyjr-cOEU30OoIv1ByubH1jt04Yb
Cant say for sure which of those sims it is but it should be very close. It could be even same sim with different mesh frequency.

I also love how they together sound on kick. 21"+8"

You filter out the impulse response tail to keep reflections out of the measurement The exact method differs from software to software but first point of call is to measure your box ground plane, tilted down directly at the mic capsule, which is at a 45 degree angle on the floor in the nearfield of the cabinet under test.

Do you know what's meant by the different named windowing options in eg Smaart 6 and ARTA? "Blackman", "Hanning", "Max Flat Top" etc. I don't think I've ever found a good explanation. Seems to me it should be a parameter you set in units of time, no?

Flat top for sine waves, half-Hann for impulse measurements, Hann for most TF or Blackman for ‘advanced’ stuff. High-res or none for electronics - with 32k or higher fixed FFT instead of MTW or equivalent.

It's a window of coefficients that are pre-multiplied with the sampled data before FFT calculation. The basic idea is to prevent sharp discontinuities at the edges of the data affecting the result.

If you visit the wiki page (https://en.wikipedia.org/wiki/Window_function) and scroll down to list of functions, you get to see their effect on a single tone FFT in terms of shaping the noise spectrum.

It's one of those thing where there is no right answer all the time, but for a given application there is often a best one.

No, wrong way to do it as your software cannot compensate for baffle step that occurs in a ground plane measurement. So DUT 1.8m off the ground in free space and measurement mic between sources (if LF & HF), 1m out. Gate for the reflection from ground to DUT.

You never did get this bit did you Kyle.
