Haun OSS Jecklin Disk

Overall quality is good, if a bit on the heavy side. However the thin foam used on this is not really very absorptive at all, which is audible as some comb filtering at certain frequencies as sound bounces off of the disk and back to the microphone. After some testing I replaced the foam with some heavy felt board and this works much, much better for reducing reflections off of the disk. It was frustrating to have to make a DIY fix on something that is supposed to be an off the shelf solution, but the results with the stock foam were just too poor to live with.
