| OK, here is where I am with the pursuit of the Snark, err, I mean Jecklin. LP record covered with 1/4" foam on each side and then covered with faux lambs wool. It is about 1.5 inches thick or 3.8cm.
I used the 4006 TL's with the trapezoid grids to roll of the highs at ~12 - 15KHz, the DD0254 rather than the diffuse grid, the DD0297. I am doing this because I am going to be right above the chorale director's podium (textbook placement) and the chorale's sopranos are not all smooth. So, DPA fixes this for me. I tried it at a lower height and the sound was good but not enough "room" so it is going back to the textbook height.
A work in progress.
NB - The paper which describes the 35cm placement of the mics also shows the mics to be parallel to each other and the disc, not angled outward with the diaphragms at the desired distance as in the 17cm arrangement.
