Scan-Speak Discovery D2604/833000 with waveguide PCT-300/WG-300 => The tweeter is 3D printed or milled adapter plate connected to the waveguide
Scan-Speak Discovery 22W/4534G00 ⇒ Probably one of the best 8 "bass-midrange drivers on the market
Measurements
Crossover
Cost example (ehighend.de Stand 06 / 2018)
Origin
From Thorsten Felbingers pen (⇒Felbi.at) the concept arose which, so to speak, "A perfect match“To my research into things Baffle geometry, sloping chamfers & my measurements different Tweeter at Waveguide fits. He just lacked the means and possibilities to develop the passive crossover ... Win-win situations are so easily created :).
See also the report at felbi.at
The speaker I'll build soon, I'm absolutely convinced of the thing! However, the Baumappe Felbi without his construction report is hardly to use, because a beautiful appearance as the Cinetor is missing and you hardly recognize anything on the inner model, especially the Erkentniss is missing where which bracing comes from and how the thick front wall is built! Also the material thicknesses are missing. It would be nice if there will be a further improvement. Otherwise, I'm very impressed, even from the switch!

Hi Alexander,
can you show a graph where the driver's phases (before, at the crossover point, and after) are displayed, as well as drivers delay (as shown here https://heissmann-acoustics.de/en/dxt-mon-vs-neumann -kh-120a / # comment-485)?
Thanks in advance.
Cheers,
Hi Boban

Here the phase plot:
driver delay:
stay tuned ...
Hi Alex,
Thank you. Looks good 🙂
Cheers,
Hi Alexander,
can you post diagram for driver delay?
Thanks.
BR,
Hi Boban

Here you are:

hello, would have to ask what price class with ner finished box are the disco m comparable? Find two new studio monitors and would like to build them myself to save costs. I'm not at all sure if they would be an improvement. Can't hear a sample anywhere. At the moment I have a pair of Adam f7 because there is simply a lack of resolution and there are other things I don't know / have heard ...
Can it be build with a more standard baffle, like the Cinetor-Evo, without changing the cross-over?
I would not suggest to do that. It would result in a remarkably worse directional behavior.
Best regards
Is there an impedance correction for Suzie Q and Disco M?
Got a small room with a 23 watt push-pull KT88 triode amplifier
Hi Patrick
Yes, it is available for all speakers, on request for the construction folder.

Hello Patrick
Yes there is!
Hi
Peut on faire la disco m simplement en rectangle ?
Thank you
Hi
tremendousness non. Les chanfreins are obligatory.
Hi,
Do the plans include the dimensions for the adapter plate between tweeter and waveguide?
Thanks.
Hello David
Yes, they do. Its a printable 1:1 template.
Best regards
Are there any plans to make this design available on lipperbau.info ?
This is your magnum opus and i would love to build one but my wood work skills are non-existent.
