today i measured 0-90deg in-room 350-20k
midrange had slightly shorter phaseplug, but it seems to widen 1k and narrowing 2k.
7cm longer plug performs more evenly.
i might need to put it into a box, theres only lossy basket baffle which helped a lot but sure it leaks, 350-900hz some of those are from room, some really from rear of midrange.

I use controlled directivity down to 20hz. And you have to equalise in reference to ordinary box speakers if you want to compare soundwise.Records are made with monopole bass usualy. Where they have more energy transmitted in low end. Ear judges the loudness by all reverberant field.
Subjectively for me sound looks more dynamic more modulation. Little bit remembers me open space concert where you get clean strong and short initial kick. Sometimes i think i hear more music in that low end.
Monopole feels more power even with the same SPL. And kitchen cabinets vibrate more
But different tracks looks more similar. Kind of less info encoded. This remembers me loudness war with more volume but reduced crest factor. This the best i can describe the sound differences.
That sounds similar to what I heard with open baffle bass. I prefer it for minimalistic acoustic instrument genres. Upright bass sounds more natural for example. Overall I like monopole sources for the sense of "envelopment". I mainly listen in a large room/outdoors.
Seems highly dependent on each specific room, recording, and individual. As usual.

it looks like this if i turn delay off, its a bit different to OB cause theres 45cm between drivers (maybe ~20cm between voicecoils.
i think genelec W371 bass has similar no delay setup against sidewall reflection.
Some day try this one too.
i believe this is DE25 impedance and 90deg polars, not true under 2k i belive that was 1300-20k sweep from rew.
DE25 easier take down with serial resistor.
i have to listen a little bit which angle to straight response, i believe that DE25 was on the hot SSC level. Tilting waveguides takes down that hot spot but affects polar responses.
And vituixcad doesnt have my processor in it so i cant slap raw responses in, i have to measure with eq´d responses. delay and level only in vituixcad
I have lots to mess with
okay, seems that 2384 and 2374 looks about the same but aint.
2374 doesnt seem to have that much peaky 0deg. i could not find that much boost from 0deg from any height.
here is vertical 0deg from 2.5m distance as high as my micstand goes over my ear level when standing to below listening spot height.
here is listening axis from 2m 0deg and 45deg.
Phase plug is vital to midrange

listening distance is closer to 3.2m which i think quite minimum speaker height like this, drivers are quite far from each other. in-room i have to mask reflections, thats why 2-2.5m max in this room.
i dont feel any that kind of problems. mid and high melts in well.
i try to be non biased allways and i have to ask my friend Legis to tell his listening experiences.
