Step 1: Remove the Speaker Grate

The speaker grate holds the speaker in place, so be careful when removing it.

Step 2: Stuff the Polyfil

Stuff the polyfil in the whole cavity around the speaker and into the sound bar. You can get a lot in there, and the more the better. The spot in the middle can be tough as you can see in the video, but if you prop it up right it should stay in place.

Step 3: Replace the Speaker

Gently replace the speaker with the polyfil behind it, make sure to line up the screws and not over tighten them when replacing the screen.

Step 4: Repeat the Process

Repeat the process on the other speaker

Step 5: Enjoy Your Upgraded Sound System

The polyfil really makes a difference in directing the sound and reducing the tinny hollow sound of the sound bar. Enjoy!
