Very pleasant reading .... thanks Joachim and all the posters for that 
Joachim, what are your "My personal/private Loudspeaker" today ?
Do you go with the Envie wide band driver yet ?
I was asking myself if a Mp²L ("My Poor Personal Loudspeaker") was possible today after reading both this thread and the nice closed Satori you developped in the Vendor Bazar ???
I explain myself more my thought. You already showed here that the Dayton wide band could be a cheaper alternativ for a poor man Loudspeaker with the MPL OB/cardioid (resist frame behind ....a little like Gilbert Briggs did with its famous OB "loaded" by a sort of velvet blanket behind ?) . But I also read with great interest your thread about the little two way with Satori 6.5".with the Audax paper yet / btw did you try the one PHL is makink today near the aerogel Audax used to make?) - the boss is an ancient from Audax as well!) but could it be possible to swap the wide band by a the last bigger 7.5" Satori at the price of a multiway territory again (as said Graaf, and a little à la Linkwitz ?)
I don't know if the Envie WideBand is always produced (last version with Alnico magnet which feet with the 60 cm wide bafle (no return side-frames for U frame ?) (and
Satori 7.5" /4 ohms SB Acoustics :: 7½" SATORI MW19P-4 <font color="#FFFF00">NEW! </font>
Satori 7.5" /8 ohms SB Acoustics :: 7½" SATORI MW19P-8 <font color="#FFFF00">NEW! </font> (this last for a MTM cardioided OB with more efficienty- back resistiv frame- ?)
I like both the idea of a passive filter but the Under the 120 hz max with subs + plated embeded amps (dipole or not : sealed servo sub?) and the cardioid OB to allow a gap between the front wall and rear speaker at 1.5 meters max ! .... with a "little" (WAF no lawer project or caveman listening room!) 60 cm width front baflle
One 7.5 " with SS amp or two 7.5" with tubed amp ? Both with an open ribbon à la Fountek ? (poor's man version : Mp²L ?)
How could perform this new 7.5" Satori in relation to the 2013 wide band Envie ? or at least with the Dayton's in this design ?
Or am I off topic in relation to your today's still open design around an OB inspired by the LX 521 of S. Linkwitz (your other thread here at Diyaudio) you listened further ?

I used this material in 1991 in the Audio Physic Medea.
As far as i know i was the first one using this material for High end Audio.

Joachim,
Could you please tell me if the resistive frame you putted behind can help to winn some dB in relation to the non damped measurements ? Just keeped for a cardioid response ? DOe sthe little u-frame helped also or xas it keeped just to have a little better low end for the 8" driver (still made?)
Thanks in advance

Unluckilly, I can't try all the design and drivers for personal money reasons, but I always learned a lot of your threads (and at least have your buffer which sounds very good to my ears, I liked also Audio Physics speakers to listened to its ! )
The motivation of my question is I'm convinced of the good articulation and dynamic a good OB design can have but I try to find a solution to avoid more than one meter from the front and side walls ! At least one of my friend asked to the driver maker here you developed the price of it !
So it's not to ask you a solution but a modest question about the back damping and what I could expect on it with the limitation I have above (room placement : which dictate also the design - so Something cardioid sounds good to me on the paper !). Listening position : classic 2.5 m to 3.5 m possible (no back wall near, not totally agree about the need of a back wall near the chair but we can exchange in PM for that if you want, I'm just an enthusiast)
I had also looked at such commoditiy for back damping : sane in a room : wood fiber for ecological house isolation : STEICO - natürlich besser dämmen: Accueil : I bet a good damping between the side walls of an U-frame (but again for money reason I don't have the fire power of you guys from germany or north Europe ! So my questions... sure my English doesn't help in the askings !)
I'm still in a Learning phase but have some ideas and first choice needs as a sensivity >= to 94/95 db, a good spl, more for the few non compressed reccording I have... less wood skill as possible (so OB, or U-frame helps but can not be a limitation )
Hope my motivation about your asking is clearer
best regards Joachim
