How does a 1/3 octave smoothed curve look? That will smooth out a lot of the room effects making the general trend more clear.



The rise between 1 and 3K I'd look at trying to flatten out as well. Generally people go for gentle down slope from bass to treble or the smiley curve (up at bass and up at treble) not usually a hump in the midrange area.

And it's final, we're done!
My father in law and I spend a day isolating the innerworks of the speaker and closing all airholes completely (just to be sure) and then we went outside for measuring.
First response was after 6,5 ms so that got me some pretty decent gating for the mid/tweeter part.

Here we go for the results
Flat tweeter: 20201101-Tweetmet-Piet — imgbb.com
Flat mid: 20200112-midflatpiet — imgbb.com
Flat woofer (with filter, did not save flattened response): 20200112-flatwoofermetfilter — imgbb.com.

Since the woofer could be made flat up to about 1100 Hz and the mid down to 350 Hz I chose a 4th order LR filter at 500 Hz. For the tweeter and the mid I chose a 2nd order LR filter in the hopes of a natural sound (not to obvious the sound was coming from the tweeter). I chose 2800 Hz as a crossover since the tweeter was flat up to 700 Hz (almost) and the mid could handle up tot 10KHz. The tweeter was inverted (because of the LR2 filter).

This is the result: 20200107-LR45001600 — imgbb.com
Full sweep: 20200111-fullsweepfinalfilters — imgbb.com.


The result inside was stunning for the mid/tweeter section before DIRAC, with superb clarity (unlike anything I've heard).

I just measured in DIRAC and I am again very impressed with the results of base control. I had a few room nodes which DIRAC filtered out greatly.
That is the end of my project so far.

Hey Tony, that is probably so. I even constructed an extra preset (LR4 at 3500 Hz) since this should result in the best phase result. What is really nice is that DIRAC only needs to correct up to 200-300 Hz and above it the frequency response sort of follows the desired curve already (Screenshot-20200113-214431 — imgbb.com).

I would probably correct the midrange "peak" - maybe the one higher up also. As it is close to the xo maybe its best done with the dirac system?

Yes Dirac covers this very easily.

Dirac filter applied. But I kind of like the sound when correcting only up to 300 Hz or soScreenshot_20200114-145215.jpg
