Microphones consume very small power, only tiny amount heat generated and could even not be detected. (Total maximum with 8 microphones, 1.09 watts)
The small holes are not for thermal consideration, but for cable through.

Hi. The reference to a "thermal exhaust port" on your sphere microphone ... I'm pretty sure it was actually a "Star Wars" joke.

probably because the sphere resembles the Empire's Death Star to the member who typed the joke.    Just guessing, but I am sticking by my guess    >:D
music IS love

When you get confused, listen to the music play!

Cannot say CSM88 is the finest Blumlein stereo microphone, but...
It is the only single body, 1/2" true condenser Blumlein base on a pair of single diaphragm structure.
All the other single body is large condenser (not single diaphragm), or ribbon.
Or, it is single diaphragm, 1/2" true condenser, but not single body (have to mount them together).

So, I came up with this design: Almost single body (pre-mount into a minimum size, and operate as if it is single body), still Blumlein stereo and 1/2" true condenser.
But, user can re-configure easily, and the capsules can be mounted elsewhere, to form a different pickup setup.
Which one you prefer?

FSM, brief from Flexible Stereo Microphone, FSM78 is a combination from FSM base plus a C7 and a C8 capsule for MS configuration.
The capsules are time aligned at the lengthwise orientation, which can not be met with front to back capsules layout where S capsules always capture with some delay at lengthwise orientation.
The disadvantage with this layout, is there's no ready make low cost blimp as those simple tube design. For this reason, FSM78 is supplied with a custom fit foam wind screen.

FSM78 fitted with the custom fit foam screen together with a break out cable in the carrying case.

There was a pair of B9Audio mics for sale in the YS earlier this year and the owner indicated that he could put the B9 capsules onto a Schoeps mic body (like a CMC6) and they would work just fine. So is it possible to screw the B9 capsule onto a Schoeps active cable or alternatively use a Nbob cable with a Phantom Power Adapter?
Mics: Schoeps MK5's, Schoeps MK41's, AT853's (C,SC,H,O), DPA 4061's
Preamps/converters: Schoeps VMS52UB (x2), Nbox (x2), E.A.A. PSP-2 (x2) Grace Lunatec V2, Sound Devices MP-2, DPA MMA6000, Naiant Tinybox v1.5, Naiant PiPsqueak, Church Ugly, Apogee Mini-Me, Benchmark AD2k+

I thought about this but don't have access to a set of Schoeps kc actives . would love to see if possible . i would spring for a set of cables if they worked . the B9 amp is used on all the card ,omni and hypers, including the v's.While no Schoeps they sound  great and are a third the cost.

Question, and apologies if I missed it in this thread or elsewhere, but what is the difference between the CMP1 body and the CMP1C (direct cable out)?  Are there photos of the two?

edit - Answered my question.  I see the CMP1 body in multiple photos now, and the CMP1C with the FSM88 stereo mic pictures.

While i have seen no pics of the cmp1c ,i think it's hard wired at the back of the cmp1 ( xlr end ) . I could be wrong since there are no pics.
