I am just getting my measurement software/hardware setup and looking to get started on doing some measurements of various horns/drivers I have (a bunch). One thing I thought of making is a turntable to do directivity and polar measurements which is key to modern designs. It seems to be a relatively simple concept but was wondering if anyone rolled their own and has a nice design?
My measurement setup thus far:
1) Omnimic V1 (updated the software)
2) Bought a little amp with volume control for measurements as most of my equipment is tube based and thus complicates pure measurements.

3) Have Soundeasy
Recently decided to invest in the "full monty" setup since I have so much vested in speakers/drivers/projects.
3) Earthworks M30
4) Focusrite Scarlett 6i6 (was on ARTA's tested list)
6) MiniDSP 4x10 (intended to prototype the crossover)
7) ATI 1504 (for use with above, but already had it)
Also downloaded HOLM, REW for good measure (pun). Will look at PCD too. Once I get all the measurements I'll need something to design the crossovers in.
Some challenges to good measurements include my room, which is rather small (think 12 x 20 but 12' ceilings) and cluttered. I do have a lot of RealTraps on stands that I can move around to block first reflections in measurements.
