My measurements where close to the manufacturers specs.
You can look them up on SB Acoustics :: Home
Gonir did also some comparison on www.audioexcite.com

They are very close to the published data.

Here you have more info on the Satori 4 Ohm driver:

Default Kairos write up posted

I have opened a thread on the Meniscus forum for discussion of the Kairos loudspeaker kit (it is their, after all). There is a link in the thread to download a 23 page pdf write-up on the Kairos design, which covers a lot on the Satori drivers themselves. I know several people here were interested in the write-up so here is a link to the post:

Enjoy,

Nice write-up.
Unfortunately it does not contain the actual crossover but that is OK out of the reasons you mentioned.
I also made an alternative phase linear crossover but of another type that has the tweeter in phase. It works with a symmetrical rising response near the crossover point.
Lipshitz and Vanderkoy have shown crossovers like that in the late 70th when i studied tele communications but as active filters.
They also have lobing problems so in the end i decided on a 2nd order all pass.
You could argue that this is a 2nd order L/R but that is a bit confusing because some call the 4th order L/R also 2nd order. I think there is no official second order L/R only 4th order. That kind of confusion is typical in engineering. By the way Linkwitz and Ryley have not being the fisrt ones that proposed all pass crossovers.

Here is an interesting write-up that also has references to Garde, Linkwitz and Lipshitz-Vanderkoy.

here you can download a primer with other references :
CiteSeerX — A Primer ? Linkwitz-Riley Background ? 1st-Order Crossover Networks
Attempts to linear phase passive crossover go at least back to 1971, the classic Small paper on constant voltage crossovers.
Really nothing new here but like Jeff said :
The Satoris with their wide frequency response and overlap allow this kind of crossovers to be explored. I think that is good news also it is old news.

Here are some pictures of my current setup. I sit close to the back wall.
The speakers are around 2m from my ears and quite far apart, maybe 3m.
There is no hole in the middle of the soundstage.
The monitors sit on high stands so that my ears are between the woofers and the tweeters.
I cross the Satoris over at 80Hz with a 6dB passive filter to my active M-Dipole bass.
More information soon or just ask me.
