Used these on my recent speaker install and these are very good quality. Thickness was perfect and adhesion worked very well with no issues! Highly recommended!

These foam rings significantly improved the overall sound and bass response of my aftermarket rear speakers. They were a perfect fit for the rear speakers in my 2001 forester. I did not have to use adhesive and they seal against the speaker cover perfectly. I didn't end up using the center foam pieces since its pretty tight in the door.

Placed these around my new Infinity 3.5-inch two-way door speakers. The medium dense foam held the factory grills and door panels from sympathetically buzzing in response to the more efficient then OEM stock speakers.

It seems like there are way more 3.5" speakers on the market vs 4". And I don't understand the hexagon shape? Speakers are round right? I made it work bc I needed filler for my dash speakers. Big voids when you upgrade factory in a 4Runner and it helps.
