I am rigging a setup with the 12" disc, covered with foam and then that covered with faux lambs wool and adding a set of DPA 4006 TL's. Jecklin used these in his design so I am hopeful of stellar results.
Again, I would go with the 35cm. It has been tested; I trust Schweiz Rundfunk. |
I also have a 12" disc and plan to use the 8020 omnis, but in reading through the original Jecklin manuscript I notice he recommends using diffuse field equalized mics rather than 'flat' ones. I imagine this would be quite significant as many users say that they like using the disc because they can afford to place it further away from the performers and still get a pleasing direct to ambience ratio pickup versus using comparable A-B spaced pairs ? Perhaps the use of diffuse field mics contributes to this ability to work at a greater distance ? I wonder if I'd be able to generate a similar HF response lift at the mic by using a 'pressure build-up ring' similar to the MKH-20, or even 30- 40mm sphere balls ?
Is there any consensus on how thick the disk should be, with the base plate plus foam padding and sheepskin ? I think mine is likely to be around 3 centimetres when it's finished....and I'll be mounting mine on a 35 cm spacer bar to match the disc diameter. Finally, is it desirable or essential to mount the mics centrally across the disc diameter, or is some amount of offset (forward/back) helpful in getting convincing imaging ?
Thanks for your help.
