You know what joins acoustically? A single full-range driver. If you ask me, that speaker is WAY too close for the *SIX different signals* from the four drivers+two ports to combine into one cohesive wavefront. You are guaranteed massive phase distortion as you sweep from woofer to tweeter. You have even more phase distortion thanks to the 3 crossovers. Plus comb filtering from duplicated woofers. Plus the "transient distortion" of mixing ribbons with conventional cones, AND the immense group delay inherent to a ported speaker. I wouldn't let this monitor in my studio, let alone use it as a reference for 200+ tests. This is insane. You did so much work. It's like building a million dollar racecar and starting with a flat tire.
Very intersting to see the making of of this! And so much passion, nice! So many mics already done, and so many more to go :P A next step for your project could be a VST where we could select a source mic and choose a destination profile, like simple ToneBooster Morphit do for headphones or sonarworks for speakers/headphone!

Tremendous work that effectively proves that the microphone choice is virtually irrelevant in studio practice when you process audio in post. When all other variables are equal it all comes down to the frequency response which can be easily emulated digitally. Mic choice becomes a thing only when it is used live.
This is really interesting. And I know people say it's a bit off-putting to be inside an anechoic chamber, but after listening to it for a few minutes, I thought it sounded really nice.
@@AudioTestKitchen Hi Alex. You're welcome. Very cool video. I'm just curious. Are those compressed fiberglass panels covered in fabric or are they dust free?
I appreciate the work which was putted in. But to select this monitor speaker was not a good choice. It would have been better to use a broadband speaker or koncidence koaxial speaker from 100-200 Hz above to avoid positioning problems with the capsule and of course problems of cancellation / comb filter / time alignment / crossover effects. And the choice of music and vocalists was far away from perfect. Many people make their decision for a mic for human voice based an reproduction of sibiliants. So you should youse a text with a lot of sibiliants to make the comparision less time consuming and annoying. The work of different voice over artists which DO NOT SING would have been extremely useful. For me, Audio Test Kitchen is irrelevant because of this, although I think that the test procedure leads to results.
curious how it was decided to use a speaker with so many drivers vs a two way or 1 full range speaker. in question too is how close the mic position is; seems you can back it up a bit to allow for 4 drivers to sum if there’s no reflections.
Thank you for good work. But what about mic polar pattern? In anechoic chamber they can sound the same, but in actual rooms they can sound very different because they capture reflected sound from sides, back and top of mic. How you resolved this problem?
Hi! Many thanks fot this great video. Tell me please, how did you define the target point of the ADAM surrogate speaker? According to the laser, it's not between the tweeter and mid woofer, but the laser point was right at the bottom line of the tweeter. Is it the best spot for every horisontal speaker with a ribbon driver? I thought the best point was right at the center of the speaker between the woofers. Was I wrong? Thabk you in advance for the answer.
Hi! Im an audio student in university in Texas, and happen to have access to an anechoic chamber and an interesting assortment of mics that werent measured during your tests. I was wondering if there was any way that I could get into contact with you to discuss methodology and considerations in your testing and measurements. I would have sent an email to your business email, but seeing as this isn't exactly 'business', i didnt find it entirely appropriate. Let me know! Thanks!
@@thedome765 We are excited to add many more microphones of all types in the future. Please join the newsletter on www.audiotestkitchen.com to find out when we release new gear and content. Thanks for asking:) -Alex
I was worried about the airflow, as well, but somehow the temperature was really stable and it was quite comfortable all the time. There’s no HVAC coming in or out. Most of the time we are working in The chamber we have the door open and then seal it for capturing recordings. Thanks so much for your comment! -Alex
The goal of an anechoic chamber is to remove room artifacts from the acoustic device on test. We recorded vocals in there to capture them as cleanly as possible.
Hello Audio Test Kitchen, thanks for everything you've done. But I just noticed that the SM58, SM57 and SM7B disappeared on the list. I'm wondering why....
In my opinion this is a flawed experiment. I understand that the intention of utilizing a recording played through a modified studio monitor is to avoid the variables that come with live human performance. However, by recording the performance with a microphone and playing it through a studio monitor, you're only recording the information that both the microphone and the studio monitor are capable of producing. Essentially, you're comparing microphones that are recording a series of samples which are inherently limited in their information, whereas a live human voice is not.
I disagree. In this experiment, of course they are using the voice as a variable of recording stable information. But what we are talking about here is how we can constantly record a consistent sound, and how the microphone will pick it up. A microphone does not determine what it is recording, whether it is human voice, an instrument or etc.. it only reacts to vibration from the air which is sound. So regardless of what you are recording, it doesn't really matter as long as the recorded information is consistent on all microphones. Also, anything beyond the information we recieve on this experiment is also beyond the capabilities of human hearing so the slightest miscalculations would not be audible anyway.. it's just going to be math.
It's a difficult, dilemma, Altuz, it's true. The alternative - every microphone receives a different performance - is far worse. We didn't believe it was possible to replicate the human voice until we spent months perfecting the process. We didn't stop until we couldn't tell the difference between the live vocal and the re-amplified voice.

@@MikeBroderick33 compressed fiberglass panels with no covering. Surprisingly little dust after all these years.
@@AudioTestKitchen Very cool. I could use a couple of those. 😄 I bet they make great bass traps.
I believe any unpleasantness would mostly come from talking or listening to other people, likely in a more relaxed conversational situation.
I love it! I did some projects in anechoic chambers and it is such an amazing room to have

Thank you Lucas. The Harman team is indeed amazing and generous. Please help us spread the word!
That is the best test ever! Thank you to showed us the way to test microphones!
Our pleasure!

Do you hire in Europe ? 😜

What's the difference between that room and a recording studio

Hi Sorrow Over. That was a temporary glitch. Those sure dynamic mics are back in action. Thanks for noticing!
Good stuff 👍🏼
Thank you!
Thanks!
Nice to hear people under the stairs on the test. Rip double k
Double K gave us a gift that will keep on giving to many many Musicians. Thank you DK!
dang what happened to this channel? no results on the mics no new videos of anything ? 😢

Thanks, Migz. You've got it - you can't have any variable except the microphone itself.
