Hi fellows,
I re read this thread and do not think my question is worthing rigth now a new thread so there I am.
What, please, would be your advice for a upper mid 5" to 6" above a 12" paper (Faital 12PR320). Cutt-off 400 hz to 500 hz to avoid BSC in the passive mid unit filter.
Sensivity not clear to me for the moment. But at XO between 89 to 92.5 db/2.83V in relation to the inputs of the OSMC thread or Andromeda Nova from Tony Gee or Gravsen classic 3WC. Differences certainly explained by room gain and BSC targett choices.
Upper XO 2k to 3k hz. Treble unit not chosen yet but quality loudspeaker targetted.
I am lurking on polypro from Aurum Cantus or Skaaning if the last is better (?). Fear that the papers will be perhaps too shooty (?). Purifi or Volt not an option due to the price and anyway wants some life hence 5 to 6" size planned for a livingroom so no dome. Full range with their low wattage perhaps not an option as well cause mono passive amp. Satori TX too polite and Satori 16MP a little too edgy ? 8" not an option as I want to avoid 1k to 2k hz cut-off and still preserve some good imaging (off axis consideration)
Do you experienced seamlessy sounding between a paper and a polypro or anything else hard cone ? I lile the details hard cones give but I am a no church guys for the choice at the end.
For the moment drivers I think about :
Aurum Cantus 130F1 (composite polypro, no sandwich)
Audax 13 aerogel (sandwich, but raged response and impedance above 1k hz)
Peereles NE149W (people like its sound but maybe sensivity a little too low low with less than 88/2,83V for the Faital12PR320
Skaaning 6" Cquenze ( idem for low sensivity as above ? Detailled but too lush sound (?), not so flat response)
BMS 117S (paper and low distorsion, 5", no reviews found)
SB Acoustic 16MR/8 (paper low disto, too much shooty/edgy the Satoris ?)
Mabaat ST260 with Faital HF108R compression but with Xo at 600 hz ? ( I am not confortable for a XO above 500 hz but again...no chapelle, I really dunno)
Thanks for your experience and thougths for a passive filter context.

Late to the thread, but it's a good and important discussion. In many ways it shows people's preferences as much as anything. Those preferences are usually born from experience. I've heard great midrange from so many different drivers that it leaves me little confused. 
W.E. 15A, large multi-cell horns, Magnepan, Quad ESL, Morel domes, horn loaded Lowther, Eminence 8 and 12 inch cones, little Fostex, small Foca. Altec Coax. Generally for me bigger is better, but not always. And I've heard "good" midrange for all sorts of things.
As a number of people have stated in the thread, the driver does make a difference, but implementation and maybe the room are also huge factors. Starting with a great driver does help, but great doesn't have to mean $$$.

Hi Pano, thanks for the input. And not talking about caps as I found they add their mix in the final tonal. I remember your advice for the Emminence Beta8A. Certainly a good for someone wanting to horn the tweeter and accept a 1k to 2k XO... I am not confortqble with (at least from theory).
I have a Focal 5N333 on the shelf but maybe a little short with 88 db/2.83V thanks Dibirama italian site measures. And not so great souvenirs from it (it is a paper with a top plastic pelicule.
Also see tye last metal from Mark Audio with no spider. My daily loudspeaker is a 13 cm metal and I like it but fear from the little 20 W power rating in front of the more hungry Faital 12".
What worry me the most is maybe the material mismatch for a XO at 400/500 hz but I really dunno if it can be heard ? I would say objective parameter are the distorsion and breakup figures in a mid but dunno what matter the most. Although I have the idea caps are expensive and easy filter is certainly to consider. Just my budget is not infinite, the rest I am open to advices and experienced trade offs.

Thanks for chimming in. People say they are great but I have forgotten to say I d like to stay 8 ohms everywhere as per Mathias in the OSMC thread. No Scan Speak in my list cause sensivity too much low for the 12pr320 cut off.
BW mean = sqrt(400*3000) = ~1095 Hz
Eff. dia. = ~34400/pi/1095 = ~10 cm dia.
Sd = ~10^2*pi/4 = ~78.47 cm^2, so whatever driver(s) comes closest

Hello GM,
Which copes with 4" to 5" drivers.
What about a little more like I plan ? Overkill ? I know a 4" will give rhe best soundstage but what do you think about more Sd in living home hifi; more * better sound (whatever the * ) ?

I’m using a pair of these (BMW p/n65136922215) for a little while as full range, aluminum cones work great for the pennies they cost.
Don’t have that seductive sound of a paper cone however. I wouldn’t mind trying some of the regular, standard option parts.
Is hard to beat a 4” for vocals/midrange.

I'd like to try this mid (or the Rosso for half the price)...

And regarding the Ellipticor dome... Its presale price is... $2,500 😳. I think I'll do a WMTMW with those 🤣.

Another driver that needs mentioned is any driver with a Curv cone. Well damped, no breakup, and smooth with detail. I have really liked the U18, U16, FU10RB, and the old CSS WRX drivers. I've not heard the U22, but would like to.
I also really like woven glass fiber and carbon fiber cones for midrange. Dayton PC, PRV 4MR60, etc.
These are all light and stiff cones, with edge to center breakup reduction by the internal cone boundaries the fibers make. This is no different than the SS slit revelator mantra and it works well.

Hi Wolf_teeth,
I lived with a Proac D15 with the Seas Excell wooden carbon, not bad indeed, this loudspeaker can go very high SQ since you have swapped the Solen polypro that were shooty with the SS 3/4 tweeter. My last and first diy was with the Scan Speak 10F as well. Sure those plastic are good. One I would like to hear is the glass fiber from Wavecore. But too bad sensivity for 8 ohms in my project. Is the Seas U16 sensitive enough, i.e. 89 db/2.83v at around 400 to 500 hz from your measurements?

Here we are...you talk about the seductive sound of paper...what are the ones you like most, please ? I am not against a colored thinghy if it is nice for ears. I do not remember the sound of a polypro but always liked paper and Audax Aerogel. By the way too bad than Audax which is a Harmann owwned enterprise iirc does not try to improve their motors... Quite old by today standards.

Well, the pioneers chose a ~70 - 12.5 kHz tri-ax 8" (W.E./Altec 755) to be sure and get the vocals as life-like as possible, so this historically been my go-to choice. 🙂
