## Description

4 PCS Car 6.5" Speaker Voice Coil, Slow Rebound Sealed Speaker Circle to Avoid Sound Diffusion, Improve Speaker Sound Effect Bass Pad, Universal for Cars Speaker Blockers Accessories (Black)

## Features

- Excellent Material: This speaker voice coil gasket has good waterproof and air leakage resistance, reduces resonance, and improves the sound quality of the car speaker. Resistant to high and low temperatures, it inhibits the adverse conditions of ice in winter and humidity in summer, and is durable.
- Fill The Gap: The speaker pad fills the gap between the door panel and the speaker, and the sound waves are almost all emitted, which will not cause the door panel to resonate, ensuring that the speaker can better play the box effect. In addition, it can also provide wind and rain protection if water enters the car door.
- Improve Sound Quality Effect: The speaker pad can absorb the echo of the car door, avoid the diffusion of sound quality, and enhance the sound effect. Create a more three-dimensional and advanced sound quality for your car, eliminate driving fatigue, and enhance driving pleasure.
- Product Details: The package includes 4 pieces of 6.5" speaker bass pads to avoid music from leaking between the panel and the door. It forces all the sound into the vehicle's cab. From chaotic sound to full and rich, it improves the mid-bass of the car speaker.
- How to Install: The product has adhesive tape on the bottom. Stick the ring to the upper edge of the speaker and the circle to the suction area below the speaker. The gasket is soft and flexible, and it is not easy to deform after long-term use.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excelent Product.
*by J***E on May 20, 2025*

I haven't put these to use yet, I got these for an upcoming build.The rings are about 1 inch thick. The interior diameter is just a little bit smaller than the exterior of the basket on my Polk 6.5 component set, measures roughly 5.5 inches matching the item description. The Exterior diameter measures roughly 6.75 inches also matching the listing.The foam is very soft and feels like memory foam. Though it is 1 inch thick uncompressed it will compress all the way to about 0.25 inches without any issue.The backing is a 3m adhesive which is tried and true.Comes with the center foam as well, this could be used to help silence vibrations in other bits of the door panel. Or if you have a good way to cut it could be used to make rings for a set of 3.5 speakers too.

### ⭐⭐⭐⭐⭐ Quality memory foam, great deal
*by C***O on May 22, 2025*

This is a great deal on a set of four 6.5" speaker foam rings and corresponding rebound pads. The foam seems to be a closed cell memory foam that is very flexible and squishy, so it seems to depress without contorting into the speaker ring, So, if you have a very tight fit, this would be a good choice as it compresses quite flat if needed. Again, it's basically a memory foam ring. The adhesive backing is a very, very sticky 3M, which is always welcome to see and instills confidence in me that it will hold firm in place. Considering you get four rings and reflection pads, I consider this quite a good value for the set.
