My wife alway's complains about the speakers. Now with the big 50cm kugelwelle she somehow finds them not that ugly.Although she now complains other wifes find them ugly.
Great job! However if I did the same and put them in our living room I would get a divorce.

Yes, I like Amphion speakers, but I prefer the smaller ones. I have listened to the Kryptons at audio shows, but I couldn’t say that I was impressed by them. On the other side it’s not fair to judge a speaker based on listening at an audio show.
The Amphions has a special sonic character by using large Waveguides. It would be nice to test something similar e.g. 2x ScanSpeak 18W Revelators with a ScanSpeak tweeter in a large 8” Waveguide crossed somewhere between 1000-1500Hz.

She will not do that to her self and have bad hifi after the deforce.Great job! However if I did the same and put them in our living room I would get a divorce.

How do you find the Wavecor drivers?
Any reason why you are not considering Autio Technology like Shinobiwan?
I haven't got them running yet, but they certainly look nicely designed and well built.
I chose them based on the measurements here: http://www.wavecor.com/SW182BD01_in_Voice_Coil_Feb._2010.pdf
Also the fact that it models well in my application (Small sealed enclosure) and looks nice
No, no particular reason besides that I like ScanSpeak drivers and that I wanted to build a reference floor-stander around the 15M/15W mid-woofer.
However, I have a small 2-way project in pipeline for the Audio Technology 15H.

i´d like to do the same but with this driver as midrange
10F/8424G00
10F/8424G00 - Scan-Speak 4 inch wideband coated fiberglass - Europe Audio
With the limited Xmax and Sd and high Fs you'd need to XO over 250Hz.
I only asked becuase i am considering their SW270 with their passive raditaors for a compact subwoofer.
Subwoofers
I would also recommend SS Illuminator with Be tweeter as I have build a 2-way using these drivers.. that Be dome tweeter is amazing, have very good off axis dispersion, excelent imaging, improve midrange performance, while the midbass is excelent producing deep bass full body and extended..

Btw, why not go for a 4-way sealed design, rather than 3 way with double woofer? It's still on my wish list someday to build a 4 way with SS Be tweeter, Vifa DM75X dome mid, 18W Illuminator and 23W woofer..
It's interesting the way we all have our own ideas of what constitutes a "reference" system. I'd like a super fancy B&C system, but I don't understand my attachment to this brand... It's like the way some people cling to Klipsch, or whomever.

The DM75X might be a misfit in this set but I to have dreamt of a 3 way using the 23W, 18W and tweeter.
and your choice of drivers would be...
LOL......Yeah .......
If you like real bass I mean subbas. A closed box will never be high-end without active correction.
You can design a BR with group delay around 20Hz You cannot hear that, and have much better bass-response as you can get closed. I think closed box lovers confuse sub-bas with less controlled bas.
Here a example of a high-end carbon subbas monacor sph300ctc as you see the comment on the impedance and phase is wrong. Higher group delay as closed box only below 35hz. with the port placed on the back you get subbas down 20hz in 63 liter.
To make good basreflex you need a big port 30% or >Sd.
+10........
Oh, well... I thought that this was a Seas and Scan Speak thread... but, I'd love to have a pair of the DCX50's.
B&C SPEAKERS
but they are about $600 each... not including the horn of course...

highend ? no way
Monacor looks good
quality may be ok, but average/mediocre
though prices are still highish
tho there actually may be a few 'lucky' drivers
and real good ones too
and even among the cheap ones
or maybe especially among the cheap ones
but I wouldn't get too excited about Monacor
many drivers are very old designs
from before internet
and prices are from back then too
in short, overpriced
but then, who knows what happens
prices seems to go up fast, in general, everywhere

From B&C:
"The DCX50 and DCM50 represent a new level of high quality, high performance, full range and midrange drive units. Our patent pending designs utilize a neodymium magnet assembly and a 50mm voice coil.
The platform for each design is a 5” paper cone which offers superior damping properties. The DCX50 is
the full range version and has an operating range from 400 Hz–16 kHz. The DCM50 is a true midrange device. The sound quality of the DCX series is really natural, and offers exceptional clarity in the vocal range."
I'm not saying these are better than anyone else's products, of course.
I used monacor drivers the build qaulity lacks. The materials are good like frame and cone.
The specifications are OK
medium
What is a old design? I know linearity, THD, Xmax, and TS parameters oldfasion?
It seems to me you never used a monacor driver. I use them because they aways have one I can use. I had to look more at scanspeak to I think now.

That’s the beauty of this hobby
To me what’s considered a “reference” changes over time. Right now I think ScanSpeak has one of the strongest driver unit line-ups in the high-end segment, but that’s my opinion and according to my preferences.
Any news about your project?
I had a similar project as yours in mind and being a huge fan of scanspeak I had to admit to myself the 15h52 was the "one" for my 3-way
I ended with this setup:
Raal 70-10 (If only I could get the 70-20XR!!!)
AT 15H52-06-13-SDKAM
ScanSpeak 8861T00
Expected cross freq: 300~400 / 3500~4000
Im working on it atm I'll let you know how these beauties sound together!
