That's an odd one. At first I thought the photo was squeezed, but it's 8x oval drivers in front, with 8x woofers side firing. That's one way to drum up driver sales. 🙂
Not sure I'd want to build something that complex and unusual without first hearing it, but it looks fun.

Cool speaker. There is also a Mini Orgue. A kit for the Grande Orgue can be ordered from Solen.ca for $1665cad.
The plans are on the website. Ente has provided a direct link above.
Funny, I have almost enough drivers to build this, although they are not Visaton. More than enough oval fullrange drivers and almost enough 10" woofers. The bass correction circuit is not reveled tho. The fullrage crossover is curious. Two parts of it pull down the midrage, then the parallel cap drains away the top end from all but two of the oval fullrage, the two that are at ear level. The high pass filter also tilts the response way up.

If two of them plays fullrange, there is a risk for comb effects and a ragged response in the higher range. Those oval fullrange did not look to go very high as well. There are better fullrange drivers than those.
Here is my friend comments for this speakers.
"Colored as hell. Imagine all the resonances from those chambers. Look at the drive units behind the baffle. Also if you look at the response from the drive unit. It’s very rough. Like a unit designed for a radio set. I have a vintage radio here will have smoother response!"
Would building with stiff material such as bamboo pkywood cure the problem?

Actually two of them do play full range, numbers 2&3. The other six mostly play at the low end of their range. What that does combined into a line, I don't know. I suppose that the 8 drivers combine to give a lot of low midrange, as the crossover has at least a 20dB upward tilt on drivers 2&3.
Note that this is not the full x-over network. Part is missing due to it being patented, which really doesn’t make a lot of sense since patents are public anyway..
This morning I put together the midrange xover in Xsim. I can post it if anyone cares to have a look.
Please do. Every time I've wombled through Visaton's site over the past few years, the GO has always raised a smile. It probably isn't quite to my taste, but it's interesting, and that's no bad thing. Any Xsim assessment you've put together will be worth a gander.
My guess is that the 'patented' crossover is something like the Ripole crossover here:
RiPole Subwoofer
RiPole Subwoofer
Chances are big that this is indeed the case. The woofer section is definitley a Ripol configuration.

if two of the elements play fullrange there will be cancellations at certain frequencies depending on the center to center distance.
I guess this is a compromise they made. The sensitivity is already quite low. With only one fullrange driver playing it would be even lower.
