Customer Ratings & Reviews

AMAZING! Game changer for sure.

I am really happy I got these. I didn't think they would work and thought they would be gimmicky given they were promoted as a recommended bundle, but man oh man. Rather than my sound going into my door (which ironically happens on ALLLLL speakers), now the sound goes out into my car.

What is crazy to me is that for all these years subwoofers in a box act like this in that the sound obviously doesn't go back into the box, but speakers in a car never behaved like this.

Now it's like all the sound the brand produces with the speakers actually is heard by my ears. I am seriously so impressed with these that I am leaving a review, and a long one at that.

I felt like these should be so well known for everyone and it is so dumb that the car manufacturers do not include these or build speakers in this manner. It's crazy.

Awesome!

Made a huge difference when I installed these rings on my front doors speakers. It improved the mids with tight clean sound into the cabin. It wells design with excellent quality materials.

Must for all door installs

This are essential for all door installs. Good adhesive and the most dense and supple foam you ever felt.

Great product!

Made a good seal against the door card. Inexpensive way to improve sound quality.

NVX FRING65

Fewer rattles in the door panels. Worth it For what you pay.

Not too bad

I was worried it would be thin! However this stuff has a ton of cushion! Perfect for getting that tight seal. Haven’t heard any vibration yet

Bought to use on both nvx components & coaxials

I used these front and rear on an 03 4runner. In the front, there was a bar right behind where the speaker would be. I placed some deadening and then had to cut the middle section in half. The glue was very sticky and the product seemed to do its job. The small fee for a decent upgrade.

Fits great

Super nice adhesive and pliable enough to fit around my Cerwin Vega v465c--Could require trimming if your door is really close to your speaker. Also check that the foam on the door doesn’t hit the window, mine cleared.

Nvx fring65

The NVX FRING65 is great . The sound quality that you get after installing the nvx 65 . Is superb. If you are purchasing or have purchased aftermarket speakers. This will be a great to add on . And its a cool weekend project . I just ordered another pair for the rear deck speakers .

Seem promising

These came with speakers I ordered, so that said, I can't complain. I bought NVX baffles too, so since I used those, I didn't use these. Still, the foam seems like it'll hold up well.

I may use them in a future build and will hold on to them for when that time comes.

What a difference!

I noticed a huge difference installing this in my 2007 Silverado (Classic). I didn’t think it would actually make any difference but I was totally wrong! The mid bass is so much more crisp and pronounced. It even eliminated some of vibrations I had.

Good stuff

This looks super cool I have not installed them yet but I like the materials and quality.

By jimmyotoole on October 11, 2020 Verified purchase

Great product

I think these work great. But I rushed it and ended up buying another set to do correctly. Directs sound like it's supposed to.

By Robert on March 23, 2022 Verified purchase

Perfect fit

Perfect fit. Was not a fan of the closed baffles, so I cut the back off and added these. Sounds so much better.

By Anthony on March 4, 2024 Verified purchase

Amazing quality

Absolutely loved the quality and pricing for this product. Will definitely be using in future applications.

By Ryley on March 4, 2025 Verified purchase

works great seems to be good quality foam

By Steven on June 8, 2024 Verified purchase

Really nice ... but

The product and the concept are fantastic. It could be improved simply by being a circle cut out vs an angled cut. I had to make sure that the angles didn't interfere with the speakers surface when mounting. Other than that I liked the product. You would think that would be an easy concept. Round speaker so a round cut out??

By Ron on February 21, 2026 Verified purchase

Wow! Sounds so good!

Never thought something this minor could make such a huge difference. These will take your install to the next level.

By Manuel on February 4, 2026 Verified purchase

Perfect

These fit my NVX VSP65KIT2 6.5 inch speakers perfectly. The adhesive feels very durable for both the foam ring and the backing. Both stuck to their respective surfaces very efficiently and it feels very durable.

By Armando on February 3, 2026 Verified purchase

great product

Great product no problems installing didn't really think I needed it but I went ahead and used it glad I did Sonic actually provided free with speaker purchase so that was an added benefit would buy again.

By Jonathan on January 31, 2026 Verified purchase

Great product!

Ordered these along with a new set of 6.5” door speakers. Initially noticed how well-made and durable the product was. Installing them is pretty straight forward and simple. And after listening to the new speakers, I feel that this product helps me get the best performance out of them.
