NotreDame, do we really need three different threads about you and the speakers? I get that you're disappointed, but that doesn't achieve anything.

Everybody else is probably right - you have bass issues with your room, so the end result looks bad. However, the frequency plot tells you only part of the story.

What you need to do is measure the room decay and show us the waterfal plot:

This will show why you don't hear the details in your room. Also, you need to be aware of the first early reflection points and dampen those. With the first reflections masking your music, your brain will have trouble compensating.

Oh, and yes, better speakers CAN cause issues in your room to become more prominent than with cheap ones. My room is treated very well but when I set my sub to extended frequency response, the bass extension to 20Hz causes problems in the 40 and 60 Hz areas. So perhaps that's what happens with the Munroes.

Also, the direction of your speakers' bass reflex ports can make a huge difference. If the port is on the backside, positioning it too close to a wall can cause problems which don't occur with speakers with ports in the front. With bass reflex ports downfiring, you may excite resonances between floor and ceiling which just don't get excited with the other speakers.

Hi ! I know that I made several topics already, but here I just want to resolve the problem and not fall into a polemical speech.

Basically, I always felt that my speakers had a slightly lack of high frequencies.

Here you can have an idea of it :

And here you can know "why" it is happening :

So it looks like it is a question of positioning the speakers !

First question : why does it happens particulary to these speakers ? Is it because they are 4 inch ?

Speakers are in front of me, moving them of 30 degrees does not change something in the high area.

Then, I muted one speaker, and take on speaker in front of me (I place my head just in front on the speaker).

The result is that, when I move my head of 90 degrees (= ear in front of the woofer) I hear A LOT more of high frequencies.

It looks like I have to get the ear in front of the speakers instead of the head....

But the difference in the sound is very noticeable. It looks like when you have a low pass filter at 10khz, and which would be bypassed when you turned your head of 90°.

So, any solution ?

Could it be a defect in the design of the speakers ?

yes it's a defect in the design of the speakers. They forgot to plug in the wire from the x-over to the tweeters. Send them back.

Seriously ??! What is wire and what is x-over ?!

And the brand does not exist anymore, so I can't send them back at all.

no. not seriously. people have already told you in this thread but you keep ignoring it.

and the brand still exists.. http://www.munrosonic.com/

And X-over is a type of filter inside a speaker which splits the sound up so for eg. the high frequency driver isn't damaged by bass frequencies.

By the way, you do know there are high frequency and bass adjustment trim pots on the side of the silver amplifier box don't you?

I contacted them, and a guy wich does not take parts of the brand answered me that "Munro Sonic doesn't exist anymore" and that they are under administration.

But the website is still existing.

no. not seriously. people have already told you in this thread but you keep ignoring it : people spoke about acoustic.

But here I demonstrate that the problem is not (or not only) due to acoustic.

read above, i've just edited.

Thanks !

Yes the filter knobs are turned to get more high and less bass possible.

The bass and mids volume are normal considering my acoustic.

Thanks for the x-over !

So basically it split the sound in order than one part go to the big woofer and the higher part of the sound go to the high driver ?

yes.

so you've adjusted the trim pots and it still isn't working?

NotreDame · Post by **NotreDame** » Sat Jul 08, 2017 10:03 pm

no...

Actually the pots does not make any boost, they just can attenuated the sound.

So I just seen as I said previously that the sound of sonarworks sounds like the sound of when I have the ear in front of the driver.

So it looks like the speakers delivers the good amount of high frequencies, but that I don't hear these frequencies in a "normal" position.

The fact that Munro Sonic delivers two graphics instead of one is suspicious...It looks like there is a problem in the sound diffusion and that they wanted to justify it...

So attenuate the bass then.

No. The graphs show the frequencies that you hear when the speaker is pointing directly at you and when the speaker is pointing 30' off their axis away from you.

I don't know what Sonarworks is.

[edit]

Just searched Sonarworks. Why would you put some software EQ over your output?

Seriously, NotreDame, please stop accusing Munro of scamming you. Especially when one thread would have been MORE than enough. Crusades like that usually end in moderators having a nice little talk with you.

From your replies it is very apparent that you don't know a lot about speakers or room acoustics or psycho acoustics. That's okay, not everybody is interested in these things. But when we give you advice in order to help, it would be nice of you to try and go along instead of insisting that you've been cheated.

And no, using loudspeakers like headphones, pointing at your ears from the sides does NOT provide helpful information which might help solve your problem. Unless your problem really is a huge beard or copious amounts of hair blocking your ear lobes...

If you measure your room with Carma as suggested earlier, I might be able to give you some ideas for how to improve your room. If you insist on finding your own explanations, bonne chance, mon ami!

No difference between 300$ and 2000$ speakers.
