Wow, great idea, you're a crossover master, love the mic as well considering getting one. I don't think I want to go down the rabbit hole of Crossover design but admire people like yourself who can do it. One of my favourite designers Stewart Tyler (ProAc) of which I admire their speakers a lot, spends years developing crossovers for models. Personally I think DSP looks an easier option these days and having fully adjustable real time active crossovers. I think things are only going to improve with that as well.
Thanks - fast and can stay in loop, recording changes in Frq - sweet, one of most useful feature for audio DIY selfer. Time to retire my 20 year old Clio - yup still in DOS. I have question, since I noticed you run the SB26STAC in Rivalries way down to 1.2-1.3kHz - did you try other tweeters that are capable of crossing that low w/o turning into screamers - maybe some favorites. I'm running Mark's Kravczenko KAXBL around 1.8kHz - we made faceplate from MDF. Capable tweeter, but because it starts to roll off around 1.5k it's really hard to get smooth response around x-o and I would like to squeeze more out of SB17NRX, meaning cross it closer to 1k, also the size of capacitors is rather big with KAXBL. Thanks for videos and NouRouz Piruz - all best.
Omnimic does measure phase, but the phase interaction between two sound sources (say a tweeter and a midrange) is expressed in the frequency response, if the response is flat through the crossover range, and generates a deep v-null with the polarity reversed, then there is a good phase match between the two drivers. We don't hear phase, we hear frequency response which makes response the only thing that matters and needing to be optimized.
@@javadshadzi4824 a phase give you 3d sound stage, if midrange is 40° of phase you cannot see it in frequency response, but you can hear it with muddy vocal and instruments position
@@doxzlaborathory I'm sorry but nothing you wrote in that last response is technically correct. If the drivers are out of phase, they will cancel in the frequency realm and it will change response. If you change phase, you change response. If phase is the wind, you don't see the air moving, but you see the tree branches moving, that's how phase responds with frequency response.
@@javadshadzi4824 if hightone speaker moves forward, and mid is moving also forward but with delay, it will cause muddy 3d soundstage crossover makes cutting but 6dB is not much... Our ear can notice phase difference, that is why when you put headphones and listen to that " barber shop" recording you can tell how far is everything around you, you can feel your 3d surrounding just by hearing it. Many people will tell you that flat responce speakers, are not good... The best listening experience is from one full spectrum speaker, good designed, that cannot produce flat response, but there is very nice and realistic 3d sound stage.
Very nice video showing hearing and visual changes

Great video!. How does the mic react to the room?. Still a very short sample in real time??
Hey Ron, the system can do gated measurements so down to about 200hz you can remove the room from the measurements
Are you on diyaudio?
I have many posts on there but haven’t been active the last few years. You can search there by my name.
You can see the response, but you dont see phase difference, you need a oscilloscope to see that, phase is much bigger deal than this

@@javadshadzi4824 phase difference is not about cancelation, its about not playing synchronized
