I generally prefer more flexible mic spacing than offered by most low profile mic mount bars (Kwonbar, NOLA bar, Vark bar, etc.). I regularly find myself wanting to run a spread anywhere from 20 cm - 50 cm, with variable included angle. The Kwonbars and such provide good spacing at 17/20cm and 30cm, but with fixed 90º angles. I like to run even wider, sometimes, and often want to vary the included angle depending on the situation. And besides, the Kwonbars et al aren't available for all mics with remote caps.
With full size SDCs, I achieved the flexibility I like at a very reasonable price as noted
here. But I don't really have a similar setup for my new-to-me Franken Naks. Pure DIY with all-thread and PVC tubing or some such struck me as a PITA and not terribly compact if I need to start carrying around long lengths of PVC tubing and various all-thread lengths. I stumbled across the
Shure A26X and believe several of them linked together will provide the flexibility I need.
Connecting the two mic clips ((I think they're MBHO, but nearly any other would suffice) with an Atlas 5/8"-male coupler or various numbers of A26X + a jam nut to ensure proper alignment gives me pretty good flexibility for spacing: 18, 23, 30, 38, or 46 cm. Again, all with variable included angle. See attached photo.
I had the Atlas coupler and the various adapters and such on hand, and the 4 x A26X set me back a total of $22 at Jack's Music Factory. In the disassembled photo, I have two 5/8" adapters / male barrels because the A26X 5/8"-female thread is surprisingly deep, so the first barrel goes all the way in to fill space and remove the need for a jam nut on that end, and the 2nd one connects the mic clip.
Now, the next step:
find a shockmount that handles the approximately 17-18mm diameter of the Shure A26X.
Specs for the A26X:
Aluminum
5/8"-27 male on one end, 5/8"-27 female on the other
3" (7.62 cm) long
~11/16" (17.5mm) diameter (Shure provided only an approximation)
1.5 oz (42.3 g) (Shure said 1.1 oz, but my digital scale says 1.5 oz)
