"two Type 4003 or 4006 omnidirectional microphones spaced 17.5 cm and a special acoustic treated disc with a diameter of Ø35 cm placed between the microphones"

I took some measures of my Schneider and this is what I found:

The disk is 35cm in diameter with a 17cm diameter ball in the center. The PVC disc material is almost 1cm thick. Foam approximately .75cm thick covers each side of the disc and ball. The picture of Core Sound's model is useful. The "ball" diffusor on each side is not perfectly half-round. It appears flattened some, kinda like a slice was sectioned out of the center before being glued down to the disc like roundish bubble.

Core Sound — Jecklin Disk and Schneider Disk microphone mounts

I don't have a woodshop so I bought mine from Coresound. I decided to get the Scheider instead of a Jecklin for it's "ball" diffusor. I use it with great success on orchestral, choral, large to small ensembles. The room and the mics have to be good. Close placement is needed because disc shadowing that generates a stereo image exists only inside the critical distance. For this reason you may need to raise the disc higher than you would, say an ORTF pair, to ensure that coverage from the front to the back of an ensemble is even.
