Post Directiva r1 Active Crossovers here

[Solveit]

Currently working on my take on "Directiva" and here are some early captures. These are not final, I am still playing with the crossover, but what I have is promising and sounds nice too, just mono testing. I used the REW EQ-drivers-flat-on-axis-past-XO-points method, as discussed earlier. Started with 3k but will likely lower to 2.4-2.5k as my woofer looks like it has some funny behavior around 3-4khz off axis making for a bump in the sound power there.

My version is a ported floorstander with an F3 of ~35hz. I'm experimenting with wavelength traps with the port plumbing within the base of the floorstander cabinet, as I discussed in the directiva thread, to significantly reduce port resonances. Again, its still early days with the final port tune. Measurement equipment is a combination of EMM6 mic, UMIK-1, 4.5ms window stitching to near field LF measurements. I haven't had the time to do full turntable measurements, hopefully this weekend. It should be noted the EQ's I arrived at were way off rick/ctrl/amir's, using those EQ's (from this thread) gave me a wide smile curve. The differences between driver responses is worth paying attention to!

As I said, some interesting off axis stuff happening and some things I suspect I wont be able to capture with the current 4.5ms window but its not terrible. Open to criticisms. To the music very soon, I hope~!

Nice but then you have to change EQ in listening position and all curves changing...

I have an crazy room but accepted my dips.

Can you show a REW decay and waterfall?

Can you show a REW decay and waterfall?

You'll have to enlighten me as to how to do so, and is it even insightful with a 4.5ms gate?

EDIT: Is this the capture you wanted?

Can anyone post the miniDSP 2x4HD configuration file here

Please forgive the delay but have torn down my system for some room painting. If you have not figured out, let me know. Should be able to find a config file but cannot verify it currently.

Any chance to download the Directiva miniDSP 2x4Hd file. would be great if I can get them

My apologies for the delay, had home issues that were urgent and still have not had a chance to set up r1s to test this config.

It may need to be tweaked, but will give a solid example to use. See attachment....
