This is 180 degree off axis response of
Purple = CT12
Yellow = RK12 (Rayking faux ck12) i just measured at my place. Literally the same body, circuit, grille...

It is pretty much the same thing for 90 degree response. So can you imagine the audible difference of anything coming from off-axis with almost +10db difference at 5k and 10k? Like reflection of the glass window placed in back of the microphone in a lot of studios?  Or cymbals? At high SPL?

I am just saying these are two different type capsules and i cant see the point of comparing the two...

I'm sure Philips has sold microphones before, like back in the late 80's or 90's, if they're not doing it now. I can imagine Philips rebranding those Chinese OEM electret "shotgun" mics and other generic OEM dynamics and maybe some instrument mics as well.

Philips' pro mics were rebadged AKG and Beyer mics. The consumer electrets were made in-house until about 15 years ago. These days they're Chinese and the pro audio gear is gone. The "Philips" brand consumer audio isn't even owned by Philips anymore. Philips only has electric rasors and stuff like that left and components...

But, enough OT. CK12 is much more interesting.

There were some original Philips mic designs too, though I don't know whether they made their own capsules. The EL 6033/10 is a very interesting mic: a moving-coil dynamic that can be made omni or cardioid by twisting a ring at the base of the headbasket.

That kinda sounds like it might be similar to the Shure KSM141 system. The twistable ring at the bottom of the headbasket raises a cylinder inside that closes / seals the rear of the capsule. But we're veering off-topic here... ;D

For what it's worth, i've made a few mics with Chinese "CK12" capsules (from Banzai's group-buy, a couple years ago). Can't say i recall what drilling pattern the backplates have, but i have run some sweeps and "relative"-d them against my calibrated measurement mic (sans the absolute SPL figures), and they don't look half-bad to me.

As can be seen on the left edge of the graph, it's 2dB per division. The bottom trace has 1/3rd octave smoothing applied (with 1/12 it's virtually identical to the others), the other two have 1/12 octave smoothing.

I think that 6033 was made by AKG too. Probably the contract between the two made it a Philips exclusive mic for the Pro market. I happen to have an AKG consumer mic that uses the same idea. I don't know if it's released before or after the 6033. It's also a wooden mic :D

Apparently the Maiku capsule is tuned to be closer to the ELA M 251 sound.

Is anybody who has both capsules willing to do a quick sample or measurement?

I'm just gonna go with Maiku, waiting on a PayPal invoice so I can order a b stock capsule. If the invoice doesn't come then I'll either buy a capsule from someone on here who's selling one, or I'll just spring for a CT12. (I'll be waiting another paycheque for that though, that's pretty much a paycheque from my part time job right there, the price is equivalent to $500 Canadian, with taxes and shipping probably closer to $600 before any duties)

I actually just watched a comparison between the Peluso 414 and a vintage C414 and C12A and the Peluso couldn't even compete. It sounded so sibilant on the "s" sounds. The Chinese capsule in the video on the first page (don't knoe who makes it) sounds a lot more C12 like than the Peluso 414's caspule when compared to their respective inspirations.

https://youtu.be/o7hsA-DWn5k here's the video with the Peluso 414. It's noticeably harsher all over and especially sibilant on the "s" sounds which end up being both hissy and "esshy", and even some completely different sounds you wouldn't expect sound sibilant. I'm glad I didn't pick a Peluso CEK12, especially at a price of $250 USD. If you want something bright like that I honestly think you should just get a couple RK12s and two used donor mics and build a pair. Or better yet save for a CT12.

If Peluso just sold mic bodies and PCBs I'd buy that and throw a nicer CK12 capsule and make a nice C414 clone. But $850 for that mic isn't something I'd ever be willing to spend if I can just buy a used teflon C414 and throw in a nicer brass capsule. Investment would be more, but you'd get much closer to those brass capsule C414s that sell for like 4 grand on eBay.

Well I hope no one minds me posting this in this thread but I couldn't  figure out where else to post it since I don't have a white market thread. I've made some cosmetic changes to my capsule . The acrylic is now clear and threaded as the original.
