The suck-out in directivity aspect is interesting, i think it comes down to cone geommetry and dust cap.
For sure there are not that many drivers with a similarly-shaped relatively deep concave cone with no dust cap. Only ones I think of off-hand are some Accutons... perhaps their measurements might show some similar effects?

Indeed it does. I replied earlier in one of the threads about mw16tx that problems with fr off axis vs ordinary Satori are most obviously due to cone shape. For me personally it's a weird design choice for a transducer that should be intended to be crossed around 3kHz... unless due to 5kHz resonance it's not. Atm driver looks very good, but it's usability is questionable. Maybe it'll work with Satori TW29bnwg though, and that'll be top drawer pairing.

Well that's right indeed. But he is hanging out so much at ASR that is was nearly equivalent to me

Hahaha ! I did not even realise it was him. I am looking stupid now

Anyway, I think that, just like Amirm and Hificompass, Erin's tests and reviews are some of the best things happening in the audio world right now, wherever I read/watch them

Definitely, and Hificompass website has a special place for me as it allows full screen visualization for fast and accurate comparison across drivers:
  1. I open 2 hificompass measurements of the drivers I want to compare. (2 windows, not 2 tabs)
  2. I look for a voltage giving me the same SPL in case I m comparing 4 Vs 8ohms or too different sensitivity drivers.
  3. I can instantly switch via [alt+Tab] across tabs with a given measurement in full screen
  4. I use left and right arrow to switch across levels/measurements within the same section
  5. Bliss
Are you using it the same way?

i very much like dibirama also, far from the in depth detailed measurements as hificompass or erins but i like the presentation and the number of tested drivers

i do, but i would like that all measurements where done at specific drive levels instead of fixed voltage levels for easier comparsion, and i would like fully tsp-measurments, but otherwise it is excellent

Seems like top performance across the board except for the disappointing IMD and low-end. What are your thoughts on its audibility, and do you think the IMD would be an issue if the Xmax were kept to 1 mm or below (same test conditions as in your review)?

For me, it doesn't seem like it beats the Purifi as the bottom of a 2-way, but could make for a really nice low-midrange in a 3-way or 4-way.
Personally, I don't suffer from IMD when listening to the music, but not to the test signals, so, I don't think the IMD would be a problem when keeping the excursion below of 1 mm too. The 2nd harmonic distortion puts much more to a sound signature. I'm sure there will be a persons who much more sensitive to the IMD distortion and have another opinion. It's all too subjective.
No one speaker for a while has surpassed the low frequency IMD distortion capabilities of Purifi...
