Interesting. Nice surround. Phase plug on such a small driver is questionable.

Dear ricyuyc,

OM-OF101 has a short stroke, so you shouldn't be greedy with the bass.

6 to 8 liter bass reflex will give you a good balance.

I built 3.5 liter double bass reflex.

The development team tried dust cap and phase plug, and found that the phase plug were better in many points.

surround looks very reminiscent of the Fostex Sigmas

It's no good at long strokes because of the narrow surround.
I push cone by hand, it only moves half of CHR70v3.

Default Onkyo biomimetics speaker

The appendix speaker unit of this year Japanese
audio magazine "stereo ontomo nook 2021"
is om-of101 made by Onkyo.
Onkyo stereo brand have delisted but they will make
biomimetics cone speaker as OEM.
It's cheap 60usd here and I really like the sound.
For now,I replaced in my tabaq for w4-1320.

Thank you for sharing these, Tamra.
They remind me of Fostex’s hyperbolic paraboloid woofers. Are they available yet? I would possibly be interested in testing the dispersion pattern and non-linear distortion.
