JVC CS-DF620 with Speaker Installation Kit - Customer Ratings & Reviews

Apparently, one size does not fit all 6.5" speakers...

Unfortunately, I cannot give a review on the product's performance as I was unable to use it in the manner for which it was manufactured due to incompatible size issues. The speakers I have are the CVMPCL6.5 - 6.5" STROKER PRO 200W Midrange Gold Speakers. Pairing these speakers with the NVX XBAF65 Speaker Baffle Ring Kit spawned two issues:

1) The mounting depth for the baffles is 2-5/8" (2.625 inches), whereas the mounting depth for the speakers is 2.930 inches. This minor difference was seemingly insignificant until the second issue reared its ugly head.

2) The width of the baffles is much too small for my speakers. I can't seem to find information on the exact dimensions of the baffles as I have not yet contacted NVX. But the width (diameter) of my speakers is < 5.76 inches. This is obviously too wide for the baffle because the baffle would not go on without a fight. I pulled, tugged, stretched, and strained nearly damaging the speaker. I then decided to make a few modification cuts to the baffle to accommodate the sheer width of the speaker, but the result was a shredded baffle and a traumatized speaker.

Now I'm stuck with three unusable baffles because I bought two pair!

Regarding speaker width, the CVMPCL6.5 - 6.5" STROKER PRO 200W Midrange Gold Speakers have unremovable hardware tabs attached to them that I can only assume are there to somehow protect the speaker leads. They stick out from the speaker basket making it impossible to properly install the baffle and, in turn, causing the magnet to protrude out of the base of the baffle a lot farther than it would have if the baffle were wide enough.

Regarding the attached photos, the unmodified baffle from the first pair was used to demonstrate the issue.

**** VENDOR RESPONSE ****
The XBAF65 are made for nearly all 6.5" speakers. The Cerwin-Vega pro midrange seem to be the culprit as their depth and basket are atypical.

We will do our best to come out with a new, larger "oversized 6.5" version and name it XBAF675. It will take us some time to tool and come out with it, but hope you enjoy the feedback.

Foam vs Rubber

The best thing about these speaker baffles are the fact that they are rubber vs the easy to find foam. They definitely add a nice level of water resistance with the rubber. Not to mention the sound quality improvement. It's seriously a night and day difference. Trust me, just buy them!

Protect Your Purchase

I like these baffle rings because it gives that added protection for my mid-bass component from any water that may slip through the window sill. It also helps with reducing any unwanted vibration noise. The egg crate foam placed behind the speaker on the inner lining of the door helps absorb waves to add more decrease in vibration.
The silicone-rubber material is going to last a long time and can be easily trimmed for a custom fit.

But them a must have

I makes sound project forward and also gives piece of mind of some possible water resistance........ A must have for better sound quality

By Wesley on December 21, 2019 Verified purchase

absolutely perfect!

highly recommend for a clean speaker install. helps keep from losing mid-range sound.

By Anonymous on July 29, 2019 Verified purchase

Work good, good product

they work well. just make sure your on the spot before you stick the foam on because it is sticky.

The best speaker baffles!

Love these baffles! The rubber makes it easy to mount, you could trim them but it wasn't necessary in my case. Love the little foam circle that goes with it! Improves your sound quality for sure! After I installed these baffles, all of the sounds are being directed back into the cab, its definitely louder now and adds a little more midbass.

Helps doors

Great baffles to help the high powered door speakers bang

Work great.

At the very least these create a really nice seal. The ends do fold so it will clear the door panel.

By Joseph on February 2, 2020 Verified purchase

Great deal

Got this product free with the purchase of a pair of speakers it helps out a lot looks more professional and sounds cleaner definitely give it a try for your next project.

great protection

Recommend!
Gives speakers protection from rain which to me is the best part. It also helps the sound quality.

Don't go without it

This really helps with overall sound quality, especially mid-bass in my experience. NVX offers excellent quality at better prices are than other popular sound deadening brands.

Very Thick Dynamat

This product is very thick compared to cheap versions. Priced excellent. If you want to reduce any vibration or road sound, choose this!

By Adrian on June 21, 2020 Verified purchase

Very pleased

I am glad I went with this brand. Easy application and works great in keeping my Corolla quiet and audio clean.

Awesome roller!

I'm really happy that I bought this roller. I also have two other (smooth) rollers, but this one works much better. Its little "fingers" press the NVX sound mat really well and it allows it to be spread evenly over the entire surface including all these different curves and corners. The roller is very sturdy too. After 30 sq. ft. the roller started squeaking a little, but it still keeps working perfectly! I'm sure that the roller will help me to put all 60 sq ft of the sound mat and still will be fine. Great roller!! This item is highly recommended and even "a-tool-you-must-have!" for anyone who works with sound isolation of vehicles!

Way better than version 1.

I am an installer and could not disagree more with the other review. I actually had version 1 and got it the first time I ordered a bulk pack with Sonic years ago. This version is a big improvement due to the teeth and the handle. The teeth make it way easier to get a great stick to the vehicle body. The older one was wooden handle and this one is plastic, but the plastic is rugged and it is singular piece so it is really sturdy. The older one that connected the handle to the roller part broke at the joint and this one reminds me of a sturdy broom I have from Home Depot. Worth every penny paid or free!

Good product

Sticky and did hook well to the cars body . Got it for free with my speakers purchase. Sonic electronix for life

NVX SDBSK2 Premium Stealth Black

Easy to use and reduced vibration, allowing clear sound coming from my door speakers.

NVX SDBSK2 Premium Stealth Black

Thick and heavy. I was suprised with the actual quality. For the price they’re great quality

Great value

I installed these on each rear door of my 2005 Silverado. Could really hear a difference in sound quality.

NVX SDBSK2 Premium Stealth Black

For the price, I wish it came with a bit more of the material compared to other packages, but it definitely does what it's supposed to and will make a noticeable difference if you knock on the door/panel where it was placed vs where it wasn't.

Heavy duty solid rubber.

Keeps out road noise and door panel loss of sound. Your speakers will be crisper and cleaner. Only one point of caution, you may need to modify or cut some off to fit the application. Which necessarily isn’t bad because it’ll fit most needed uses. There’s plenty there and my JL C-5’s sound amazing.

By Michael on April 7, 2020 Verified purchase

Great handy product easy does it .

Great product , easy and handy to use , the roller is well crafted and helps out a lot . Well recommend happy with my purchase . The only concern I had was that I ordered it during the week before checkout it said I would be receiving my purchase on sat it took more than a week to receive it . Other than the shipping miscue I will purchase from sonic electronix .

Perfect for tight spots

I used this to install true 50 mil sound deadening in the doors and along the floor of my f150. I installed it with this and the more traditional roller. This is perfect for inside the doors where bracing and cutouts don’t allow you to get great pressure on the material, the textured nubs give you much more focused pressure and allow you to get to stick and leave a small bit for air to escape when using a heat gun and following back up with the smooth rubber roller.

It also takes down kind of like a disposable razor giving you better access in some cases.

I used a cheap sound deadener from an online retailers house brand, the butyl rubber was not very tack and this got it to stay no problems I forgot to follow with the heat gun inside the door skins and this still kept everything secure.

Made well

Well made, not sure about the foam piece though maybe I am just uninformed but there wasnt any instructions on how to use it

Easy Peasy...

I actually installed them on the rear 6.5s that are under the rear deck panel. Seems to make a good seal to the rear deck panel & directs more music through the speaker panel holes.

By G.I. JOE on July 29, 2020 Verified purchase

Didn’t Fit

This was my mistake. I highly recommend taking a look at your setup before purchasing as they didn’t work for me. I cut them every way possible and ended up destroying them. I know I would have been able to return them if I had not done that.

COMMENT FROM NVX BRAND REP

We're terribly sorry to hear that they did not work out. Please email us at cs@nvx.com and our team will work with you to make you happy with our brand. We are coming out soon with an oversized version for 6.75" and deeper speakers (not sure if that was the issue).

By Bill on April 12, 2022 Verified purchase

Pretty good

So far, I’ve been impressed with these. You can’t expect absolute perfection with how little they cost. The lows are more prominent than I anticipated, but the high’s lack a little. All in all, I’m very happy with them. Cheap, and clean sound. For a budget friendly sound system, these are a very good candidate.

By Kolton on October 20, 2021 Verified purchase

Best baffles I've used yet.

Went with these due to being silicone and much more likely to outlast foam ones. On top of that, I like the fact there is a lip that extends to help direct sound out of the speaker grill of the door card.

Can't really say how much they helped, as I went from factory speakers to the aftermarket with these right away. Either way, they'll protect my speakers from moisture better than mounting the speakers without these, and that was the main reason I bought them. Improved sound is just a bonus if it's actually helping in that department.

By Brandon on April 4, 2021 Verified purchase

Great product

It solved the issue for the spacing gap. Make the aftermarket speaker fit like a factory.

By Rodney on July 5, 2020 Verified purchase

Absolutely love these.

This is my third time using these now and they don't disappoint. helps keep water out from my expensive speakers and makes them sound better at the same time. I was considering going with stinger fast rings initially but am happy I didn't.

By Lucas on March 10, 2023 Verified purchase

Improve speaker sound

THE nvx baffles provide a better sound inside off door making it just fit perfectly against the panel pushing the sound back into cabin. Installs easy speaker fits in remount done.

Good. Product

This work great, isolating the speaker frame from the metal of the car, therefore eliminating any rattling. It sure help to improve the sound of the speakers as well.

By Rafael on October 28, 2022 Verified purchase

great for the price

I bought these to replace my Honda speakers for the front door. Thy sound great with my radio. I can tell the difference from the stock speakers to these. I was on a budget and this was perfect. sounds good and great price

Just get them

These work great. Help keep water away from the speaker and help baffle and direct the sound into the cabin. Trust me, just get them.

It really centers the sound where you need it. I'm getting another set for my front speakers

Sound deadening

Makes the speakers sound great and looks good to plus doesn’t blind you.

By Christian on April 22, 2020 Verified purchase

Used these baffles when replacing the BOSE crap in my truck. Do they work? Can't tell...I do know that the sound in my truck is better now since replacing the speakers. I did have to cut slits in the rubber to accommodate the speaker wires, but have read that is pretty much the case with just about any speaker baffle.

GOOD QUALITY AND EASIER ON THE HANDS!!!!

I got this small pack to finish my daughter's 2020 Camry after I had already used the foil-backed version. It went on just as easily and stopped the license plate and gas gap door rattle. A big plus for me was it didn't cut my hands shreds as the foil did.

By Gerald on July 13, 2021 Verified purchase

Good quality

These things just feel good in the hand and as for the sound, they definitely seem to have improved the speaker's overall performance as far as not letting it all go back into the door. Definitely would recommend it.

Good deal

Bought a pair of kickers and they came for free, doubted them at first but it really does help in muffling the rattles from the speakers.

Awesome if u can fit them

Had some trouble fitting them in my honda accord had to modify the door panel a bit but totally worth it highly recommend these

By Spencer on May 14, 2022 Verified purchase

Very Impressive!

I initially had installed my component speakers using the "other" guy's foam baffles. After a little more research and reading expert reviews, I decided to give these a try. Upon receiving them, I was immediately impressed by how they were nicely packaged. After installing them, i couldn't believe how much dynamic sound I was missing with the other baffles. These are definitely worth every penny to get the most out of your car's audio system.

NVX XBAF65 Speaker Baffle Ring Kit

I chose these baffles to protect my new speakers from water inside the car doors. A bonus is that the flexible material helps make a connection from speaker to door panel, allowing sound to enter the vehicle and not the inside of the door.

They do make a difference in sound

I was a bit skeptical at first, but for the price, I thought I would give them a try. I have to say that I am now glad I did. I installed these with my Rockford Fosgate T1675-S (6.75") in my '18 Nissan Sentra and they fit nicely. I do have custom speaker adapters for these speakers and had to enlarge the inner mount. Other than that, they work very nicely. Directing more sound into the cabin instead of behind the door panel. I was not able to utilize the egg crate foam due to a impact bar being in the way. However, I have a significant amount of sound deadening, so no worries.

Nvx sound mat

Added 6.5 jbl gto coaxial to my front doors very easy to use clean surface and stick very easy to cut any time you door speakers add nvx mat you definitely notice the difference in the sound of your speakers it's a must best money I spent if your upgrading your speakers might as well do it right

By Big pat on June 13, 2021 Verified purchase

Good quality sound deadener.

Not enough to cover an entire door but enough to add enough mass to make a difference. Peel and stick.

By Joseph on February 2, 2020 Verified purchase

better than foam rings

This was basically a test to determine if these were a worthwhile replacement to FastRings.

Used fast rings (foam) in the past with good results. Used the foam baffles in the past with bad results. These nxv baffles are solid. The issue with fast rings is that the open cell foam would soak up moisture and degrade/ fall off inside the door. These silicone baffles are stellar and the closed cell foam piece that goes in the door is an upgrade. Made my cheapo speakers sound cleaner, louder, and noticeable better to the ears. Lows are better in particular after install.

One note, I had to trim the cabin side portion due to the height of my speaker install. The silicone is thick enough that it prevented the door panel from clicking back in place. Had I used adapter plates instead of the oem housings, I would not have had to trim for my 2009 Scion Xb. In the future I would use these again, but use the low profile speaker mounts.

By Boom Rattle Boom on March 10, 2022 Verified purchase

What a difference in sound quality!! A++

After installing literally hundreds of speakers in all types of cars I tried these baffles and I love them. The simple design and installation and sound quality are the best things about these baffles. Sound deadening materials work and are a must but these save you so much time and money. I will keep using these from here on and would recommend them to anyone looking for a deep quality sound in every installation.

Great customer service and inventory of audio products.

I liked that they had the brand which was Rockford Fosgate, they had a great selection of their products. When I received my order, there were some minor discrepancies that proved my product had been opened before when I wanted a brand new product. They helped me with an open box price which saved me a few hundred dollars and the best part about the situation was nothing was missing from the box. I will definitely do business again with Sonic and I will be ordering my other set of full range speakers here real soon. Thanks, have a great day and keep up the great customer service.
