Hi again to the community. Long time lurker here.
I am a bit tired of my current speakers (ScanSpeak Revelator 18W/8531G-00 + D2905/9700) and want to build something DIY. A tiny three way. Maybe with an added floorstander bass base if the SPL is too low.
And now the twist: The woofer will be MFB controlled. I would like to play a bit more with this technology.
I feel there is a need to have an active thread here about MFB. Moreover it will be better to have 20 opinions on the matter. If I work on the speaker alone it will be only mine. Comments, ideas, remarks - all welcome!

I am aiming at baffle width of 180-190mm. Overall height ~850-950mm to have the tweeter at ear level.
I have Kartesian Cox120 available, and will most likely use it. At least at first. Maybe it will fit to my liking.
I will start (continue) with the woofer and the MFB first though. There are too many uncertainties there.

Given the 4" coaxial what size and number of woofers are you considering for the tiny speaker?
Have you decided on the MFB approach?

I am considering a bookshelf with one 5-5,5 inch woofer, but the MFB SPL penalty may force me to add a stand with three more of the same type.
Two of those SB/SB13PFCR25-4 are sitting here in their boxes. Probably will not be used in the final speaker, but they will help to refine the MFB.
MFB sensor (accelerometer charge amplifier) was installed to a pair of TangBand W5-1138SMF, but one of them fell down from 2+ meter high shelf. 😱
The buck magnet broke to pieces and the steel frame twisted a bit. Because of that I put the speakers aside. I may return to them later.
This one is also interesting : Dayton E150HE-44
The accelerometer element is this one : https://www.murata.com/en-eu/products/productdetail?partno=PKGS-00LDP1-R
