Lack of high frequencies on my monitors...?

[NotreDame]

Hi ! I would love to get some help from some kvr members !!!


Basically, I found something weird with my speakers :

I use MunroSonic Egg100 monitors (unfortunately the brand does not exist anymore...so to find an answer is difficult in these conditions).

Since I have them, I feel that the high frequencies are not really in your face, but they are instead very discreet.

There is high frequencies, it's not like if there were a low pass at 8khz, but I always thinked that there could be more high...

Still it is monitoring speakers, I was thinking it was normal, as they have to be flat.

Some months after, I purchased a speaker calibration plugin (Sonarworks Reference 3) + their microphone.

Here is the result I had :

blues lines are the responses of my speakers, with a subwoofer in a not treated room.

So, you can see that there is a lack of high frequencies, about 6 db.
This is really strange for 2000 dollars speakers.

And this is my question : is it normal, is there something broken in my speakers ?

Also here is an important information from MunroSonic website about my speakers :

As you can see, at 0 degrees, the high frequencies response is similar to the one from my speakers.

At 30 degrees horizontal, the response become flat.

So, I have two questions :

Firstly, why the frequencies response change so much by just moving of 30 degrees horizontal ?
I never found one other speakers brand giving two graphics so differents of one pair of monitors...

Secondly, even by placing them at 30 degrees horizontal, there is just a subtil variation of the sound, but nothing similar to what I expect.

So, is it possible that the speakers are themselves bad in the high frequencies ? And so the brand explain it by giving two graphics that would give a false reason of the lack of high ?...

Thanks !

Are you sure its the speakers? No EQ on the power amp, audio interface, etc?

Yes, of course ! I even make a calibration of KRK Rokit 6, and they had flat high !! Unfortunately, I don't have the graph anymore, but it is so strange that Rokit 6 G3 (wich are overcriticized) can beat 2000 dollars speakers on the high frequencies...

Of course keep in mind that it is normal that there is big peaks in the graph I send, as my room is not treated.

Doesn't this depend on placement of the microphone, so if you move the speakers the microphone is going to receive different frequencies, just as if you move your head in the room you'll hear different frequencies being attenuated or intensified as your head/ears will move in and out of the 'sweet spot', therefore giving a different analysis plot

Mic placement is not an issue since the Sonarworks calibration uses something like 20 different mic locations to come up with the frequency response curve. Looking at the two graphs and considering the fact that you are using an untreated room, the Sonarworks result does not look particularly surprising to me to be honest. I would not worry.

mgw38, I think you are right, but how can we explain a big difference of sound by just moving them of 30 degrees ?

I find it suspicious...

Position your head in front of just one monitor so you look 90° straight into the conus center. Listen how it sounds.

Now move your head one foot sideways. Listen again how it sounds.

Do you hear a clear and annoying difference? If so: that's simply a design flaw. The tweeter only excretes straight forwards without any directional diffusion.
