Y450 Sound Enhancement Thread

Hi all,

Recently, I have managed to helped a friend to service his IdeaPad Y450 notebook, and perform sound tuning as well.

To tweak the sound
A. Extending the internal speakers dynamic range.
1. Go to Control Panel > Sound.
2. Select Speakers, and click Configure.
3. Under Choose your configuration, and click Next.

4. Under Select full-range speakers, check Front left and right > and click Next.

5. Click Finish.

B. Improve the sound signature and loudness using Realtek Sound Effect - Equalizer
1. Go to Control Panel > Realtek HD Audio Manager. 

2. Under the Speakers tab > Click on the Equalizer sub-tab.

3. Adjust the 10-band EQ according to the picture below, then click Save.

Optional. If you wish to have virtual surround effect, you may change the Environment from <None> to Generic.

C. Dolby Home Theater to boost bass
1. Go to Start > All Programs > Dolby > Dolby Control Center > Dolby Control Center

2. Check Natural Bass.
For the bass boost level, there are 7 levels. Ranging from 1 being the extreme left, to 7  being the extreme right.

I would recommend the Bass boost between Level 1 to 3. Any higher would result in softer sound with muddy bass.


You may give a try on the Sound Space Expander. The sound becomes more diffuse, but less clear and loud. Therefore, I uncheck it. If you want to have virtual surround effect, refer to B - Optional part above.

Hope you enjoy this tweaks!
