My disc is LP sized. ~12"
It's cut from Xacto foam board and covered with faux fur.
It attaches to the stand with a 3/8" bolt and a threaded rod coupler.
Yep, it's Jim here, mostly lurking... stealth like, ya'know...
I'd love to compare how the spaced omni's came out. Spear was the loudest thing I've heard since NMAS under an 8' ceiling at Mississippi Nights! It's an awesome recording. I'll seed it if policy permits.
This is my first omni experience. I usually put myself in a position where my sub cards perform well. That's not close enough for the omnis! It is hard to believe what the bass response will do to your 'normal' recording settings. The bass levels caused me to lower my V3 settings by 10db compared to what I use for the 43s. Many complain that my levels are to low, requiring too much volume control. If you have thought that in the past then you won't like my Jecklin omni recordings. But, if you want a kick in the pants with window rattling bass, crank it, and you're there!
