Improving MateBook X Pro’s Speakers

The MateBook X Pro has some of the best speakers on any ultrabook. Unlike most laptops, it has 4 speakers instead of 2: there are a pair of up-facing tweeters under the speaker grill and a pair of down-facing woofers on the laptop’s bottom corners. The crisp up-firing tweeters greatly enhance soundstage and imaging. Nevertheless, these speakers are not perfect, and here’s some ways we can improve them.

You can refer to this graph to adjust your equalizer setting in the Dolby app, but to get much better sound, read on.


Update: Huawei included the following fix in later-model MateBook X Pros.

The MateBook X Pro's speakers have a pretty awful distortion at around 511Hz. Both my unit and another at a Huawei store have this problem, so it's most likely a design flaw instead of a defective unit. The cause appears to be the bottom of the speaker enclosure vibrating against the laptop's unibody shell, and the speaker's screws vibrating as well.


Peal off the foam seal around the speaker drivers. Now, the bottom lid no longer presses the speaker against the unibody.

Put a thin strip of sponge or similar soft material under the speaker to separate the resonating components.


Per my ear, this mod successfully eliminated the distortion except at absurdly high volumes.

Other than a reduction in low treble, the frequency response stays intact. Very fortunately, this mod doesn't reduce bass.

A large part of why MacBook Pro speakers sound better than all other laptops is because they use frequency response correction and dynamic bass management. Let's give these to the MateBook X Pro.

  1. Install the latest audio drivers from Huawei's website.
    1. If using 2019 X Pro, since there is no English webpage for it right now, you can find the driver on the Chinese website. It's in the section above BIOS, and the file should say "audio".
  2. Install Equalizer APO. Apply this fix while you're at it.
  3. Search for Configuration Editor in the Start menu and open it.
  4. You are now editing the main config.txt for EAPO. Delete the default example filters in there.
  5. Right click and download this EQ correction profile (MXPro.txt) and put it in %ProgramFiles%\EqualizerAPO\config. If you have not done the distortion fix, use MXPro_stock.txt instead.
  6. Include MXPro.txt.
  7. Install DynamiQ. This will give you the frequency response you want AND the volume you need.

Note: remember to turn this EQ off when using external sound equipment such as headphones.

Before & After Comparison

Inner Workings

I used Room EQ Wizard to generate a set of equalizer parameters that flatten (±2dB) the frequency response down to about 110Hz, which is the point beyond which the total harmonic distortion exceeds 10%. I used a high-pass to filter out the distortion-heavy frequencies below that. I refrained from boosting the top treble too much and gave it a smooth roll-off instead.

This is how the correction filters look in Equalizer APO. Notice that correcting the frequency response (especially extending the bass) requires some sacrifice of maximum volume. So, I created the DynamiQ algorithm to minimize this trade-off, to get excellent frequency response AND very loud maximum volume without switching between different EQ profiles. Go install it (and read about how it works) from Github. I swear this is gonna sound unbelievable compared to what MXPro normally sounds like.

Take my REW file if you want to fiddle around. It also includes a pre-modification measurement if you don't want to do the sponge mod.

Windows volume 100 is now much quieter and I have to use the Gain. Is that normal?

Yes, DynamiQ is designed to take advantage of the full amplifier headroom provided when the system volume is maximized. The Gain should give you back as much volume as before, if not more.

Should I turn off DynamiQ when using headphones?

Yes, DynamiQ is not for headphones, so you should turn it off.

Note About Audio Drivers

Blue is Microsoft driver, purple is Realtek driver.

Switching to generic Microsoft audio drivers in Device Manager disables the tweeters and makes the sound fecal. Don’t do it. Keep the default Realtek drivers.

Hey Brad,

Recently I’ve got a problem with headphones buzzing noise. I tried to update driver, reinstall it, but without success. Every time I plug the headphones into jack I get same buzzing frustrating noise.

Do you have any suggestion how to solve this issue?

Many thanks,


Thank you Brad for your prompt reply! I solved the problem after uninstalling Realtek driver and installing it from Huawei website. I got an option to choose (after plugging headphones) headset or headphone in notification panel.

Hey brad! I tried installing APO, then set it to control the speakers, reboot, then fiddled with the EQ and preamp but am not having the sound reflect any of the changes. Any ideas? what are your settings with the configurator?

Hi Brad,

First off, thank you for all of the documentation. Super helpful!

Second, could you tell me a bit more about the 3 separate HPF’s in APO? Unless each is addressing one individual speaker, I believe they would be completely redundant.

Hey Brad,

do I loose my warranty if I fix the speaker-problem with your method by opening the notebook and so on?

Best wishes,



Good stuff. On a related note, I’m wondering if you’ve noticed a delay in “spinning up” the drivers to play the audio? I’m using the latest realtek driver. I tried mucking around with all the different drivers I could get working, and they all produced the same or worse results… Read more »


Hi Brad, thx for your guide. Can you please set a download link for your MXPro.txt EQ Correction Profile?
There doesn’t seem to be any.


Thank you for the tip. Will definitely do that as my left speakers distort strongly. Do you know what torx screwdriver size I need to open the back? Also where did you find that white foam? Is it necessary? Thx and regards,



Hi Brad, Thanks for your posts and tutorials, they are really great! There is something I’d like to ask you: when my Matebook X Pro is connected to the power, I can feel a “soft” but consistent and continuous vibration if I rub my hands on it. Well, of course… Read more »


Hi Brad, I can’t thank you enough for all the help you’ve been providing with the MXP. You helped me (and a lot of others) turn it into such a great laptop. You mentioned that your REW file has a pre-modification measurement for those who haven’t done the sponge mod.… Read more »
