For a midwoofer, a rising response that prolongates the baffle step up to the xover point is a nice handy feature that simplifies the xover design: a bigger coil as usual on a 2nd order filter is all you need to low pass and bsc, killing two birds in one shot...
Mid Qt 0,27: Could make a quite small cabinet with total mechanical Q of 0.5. So optimal time responce of mechanical system. Then the extra xmax can be usefull for electrical correction.
Tweeter: New possibilities of lobing design at crossover freq. for vertical off axis. Maybe Linkwitz can make us a optimal filter for eleptic tweeters also;-)

As commented before there exist totally different animals in SS ranges, to suit the taste of different animals too, included trolls...
I don't know why you insist to call yourself a troll. I was referring to cph2000 creature.
Yes you do have few joker posts, but you are knowledgeable - and you helped Merlin in thread with SB23NRXS, which is not a small matter.
I don't consider rising response in midrange a bad thing unless there is some anomaly (sudden peak or dip in the response). Rising response in tweeters... no extra air for me please

Thanks for these good words, but i also know i am trouble, except when people like Merlin have no problem to feed the troll...
That said, it seems that sudden peaks and dips are common place in midrange response when a midranger is also required for bass duties...

Regarding rising tweeters, well maybe my ears are aging but every day i have to thank Jordan JX92, Raal 140-15, or old Audax designs for their rising response...

I'm with GDO here, my 2-way SS design uses the simplest of LP filters. Careful choice of the first coil's H and DCR made it a breeze to work with and avoid a dedicated BS circuit, while getting ridiculous sensitivity compared to traditional BS compensated works.
Also, fantastic bass and warm natural presentation. I wish I could get the same response in a cabinet half the size though.
Otherwise the Revelators are thrilling mid-woofers.Would not mind comparing them to the SB/Satori lines head on though.

Theoretically it should transfer the drive force to the cone at uneven distances from the suspension, so cone breakup related distortion is reduced. I guess....
Mmmm... It is quite true in the woofer case that the spider is also circular...
Though i don't see the implications on the way it will behave and its linearity...
With that you put uneven tension on the cone, introducing radial resonances on the cone, that is a known issue at oval drivers. And well, they DO have a big resonance and also cone breakup. In fact, the breakup of all the 18cm Revelators (I stayed at scanspeak for comparability of the measurements) is much tamer, same for the resonances.
The Real Deal
Hi folks,
I heard those speakers. They are made by Troels G. So, the build quality is insane, really. Frank, from sales said, that they had problems to find a company, that can do that kind of machining. To the sound itself... It is very good. Very fast, natural, very low distortion. Very, very, very Although the price is a bit too much.

That's plain wrong. There are precision machining companies all over the world which use CNC. They had probably problems to find a company that would do it for their price though. Look at the crude toolmarks on the poleplates of the bass or the very uneven bevel on the edge of the poleplates, that's not status quo of metal working. I know that it does not affect the sound but if they demanding such prices, I expect them to do better. I mean, Focal does these things much nicer and even much cheaper drivers deliver better machining quality at such details.
