Customer Ratings & Reviews

A lot of materual

Ordered this for my F Super Cab. I just wanted some material to apply to the inside of the door skins. It is a lot more material than I needed. Ford already has a small amount of sound dampening material. It did quiet the interior as expected. Great product. Came with no instructions. I just used some alcohol to clean the surface first.

love it!!!

Love this product. Great price and easy to work with.

Great!

put on my trunk to stop rattles. worked great, doesnt sound like a tin can from outside. thick stuff definitely a good deal. as good, if not better, as the bigger sound deadener brands but at a lower price. i highly recomend

Impressive product

This is a very stout, impressive product. It feels thicker than the famous competition and there is no smell to it. The sheets you get are sort of a long/narrow size, so they are great for running vertically up the doors and on the outer door skin. You'll definitely want a source of heat when working with these and really, there isn't a better value for the kind of product you are getting here.

NVX 12ft.

This is great material for a great price. Ive bought multiple nvx dampening products and have been pleased with everyone. This this easily applied with a nix roller and contains the perfect amount plus some to use on your doors.

Seems fine

Used on rear door skins. No smell, easy to manipulate.

Great for Rattles

Installed this stuff in my front doors and enough for the speaker area in the rear doors. It only slightly reduced the road noise in my car, but tightened up the bass and reduce rattles by a huge degree. This stuff is easy to install and can often be bought on sale.

Good product

Easy to work with and in my opinion it performs better than dynamat!

Decent Dampening

I have had this for almost three months on my trunk lid and it has made a big difference. The rattling is not as bad as it used to be and it made a difference inside the car.

DON'T buy this if you live in arizona because the heat is too much for it.

NVX SDDK12

Excellent sound deadener for the money, very thick, no smell once applied, super tacky and sticks even to dirty surfaces. Applied in my doors it made a big difference inside the car, applied in the trunk the bass sounds much better inside but it didn't stop my trunk from flexing and sounding like it's about to explode. All in all excellent product and would definitely recommend!

Fantastic kit

This kit is almost half the cost of competitors and works just as good or better.

easy

As good if not better than others, and I saved $$$. Easy to use. Easier to press to surfaces than the stinger.

Hands Down

Hands down!!! this is good stuff for anyone, who would like to enjoy maximum output and clarity. NVX greatly enhances the timbre and the acoustic of your audio speakers,you cannot wrong with this

NVX Sound Dampening Material

This was very easy to work with. It seems to be as good as any of the more well know and more expensive brands. Sound dampening at least the doors is necessary to seriously improve the quality of sound in your vehicle.

Best way to improve your system's sound

I was desperate to obtain a warmer, natural sound in the Rav4 I had just bought and did not want to lose any storage room. I had better speakers and small woofers installed in the rear speaker compartments but was still left with a tinny sound. Advised by the installers of the improvement benefits of this sound dampener, I had it installed and then came back for more installation in the rear doors and rear floor (I had the front doors and front floor fitted initially). I am very pleased with the improvement and it is definitely worth the investment.

Awesome Stuff

I installed four 6x9 speakers in my car recently and noticed that the doors and trunk were rattling. I was recommended this sound damping for my car. I found it very easy to install and it made a huge difference. I noticed a huge change from not only on the inside but on the outside of my car. I would recommend using this stuff if you have aftermarket speakers in your car. GREAT BUY!

Best Sound Deadener on Market!!

I had bought the NVX 12 sq. ft. sound deadener and WOW!!! this stuff works better than dynamat, fat mat, second skin, you name it, it is the best on the market, with the best price on Sonic electronix!!!! It is way thicker than its competition and simple to install. It completely deadens the sound in my doors! I hope to purchase more for the cab of my truck soon because it makes my speakers sound phenomenal!!!
I recommend this to all my friends!!
Thank you Sonic!!

Major Improvement

I ordered the pack so I could take care of a few flex and crackle issues I had on my roof, I applied the material in about 100 degree heat and it stuck and stayed easily. I used the nvx roller to adhere it and it worked nicely. The difference was night and day, it's tighter, cleaner and harder hitting. I did 2 layers above the subs and 2 layers above front seats in my ext cab pickup. Im running 2 15s on 3000rms so you know if it worked for me, it will work for you

great value

It's great for sound damping i recommend this product for sound deading in any application

Good

This sound dampening is great. thick and does the job. Has been on less than a year so the long run I dont know yet but so far great product.

Great product

Very easy to work with and gets the job done. My rear deck and trunk lid stopped rattling and now my headliner started. Highly rcommended best bang for the buck

Good stuff easy to apply does the job

After an accident i decided to treat 2 doors with this product. The other 2 doors use the Raamatt product which is more expensive. Application and overall sound damping is very very close. Next vehicle I will likely do the entire job with NVX. It is amazing how far this stuff has come since the original tar no stick heat gun application stinky dynamat product back in the 1990's.

Very Thick

This kit wont take your stock stereo and turn it in to a pavement shaker but it will help kill rattles and really helps clean up the sound. Its thick and very sticky so installation could be done by hand (I just used fist pressure) to work it on to the panels and make sure they are clean! Its somewhat easy to contour to corners and edges once cut in to smaller pieces and best of all, no smell!

Overall, my road noise was still there (pretty sure you need to deaden your entire car for that be noticeable) but I did find my music with a lot of mid, such as metal, sounded MUCH better in my standard coax alpines.

Awesome! Better than Dynamat!

For one this stuff is thicker. And half the price of Dynamat. I used the bulk kit in my car and loved it. Made a huge difference with road noise and unwanted rattles. I would highly recommend this to anyone!

NVX SDDK12

First sound deadener I've ever bought, worked great, easy to work with, helped with road noise and really brought the bass out in the front door speakers of my Cavalier!

Magnificent!

Don't waste your money on daynamat you can get the same quality at half the price with nvx. Definitely recommend this.

Sold for life on Image Dynamics!

I am so picky when it comes to buying products. I do so much research that it drives me insane. I researched many speakers in the price range of the Image Dynamics CXS64 v.2's before I decided to take a leap of faith and purchase my first Image Dynamics product. It has been the best buying decision I have ever made in car audio. These speakers hit so accurately and sound so realistic that it will make your mouth drop. They create a 3D sound stage and are very low fatigue on your ears thanks to the silk tweeters. The mids hit hard and accurate as well. Very clean mid and low end bass. Do not hesistate on these, unless you want to step up to the 500+ range of speakers, this is the best you can get. There is a reason why their name Image Dynamics has the word IMAGE in it! :)

Search Is Over

I got these after other products fell apart or quit working while still in the warranty period. Searching for a replacement speaker for about a month,I been searching and searching for a good musical powerful speakers. These sound amazing. I have a 05 Buick Lesabre so the tweeers are on axis in the factory door sill. Kenwood x996 head unit and kenwood excelon xr-4s amp. the speaker are underpowered by 5 watts so, they can take a lot more. High are perfect and the mid bass is very good. Everything flow very well together with these speakers. I listen to R&B, old school hip hop, classic rock,jazz and funk music. Heart magic man sounds very authoritative and full with these speakers. With jazz music you here every part of the brass section. They sound like they are in front of me and sound dam good. Some song i listen to a million times before these speakers came out good but with these i can here stuff i never heard before like birds in the back ground chirping. I never knew that it was part of the music until I bought these. Very Very Musical Speakers that reproduce music like it was meant to be heard even at loud levels crystal clear. If your on the fence about these,get off the fence and get these. You will not be disappointed. Image Dynamics fan for life.

Awesome!

I went back and forth between these and a comparable set of JL components. I'm totally satisfied with these. Crisp, clear highs and strong mids. I'm pushing them with the head unit right now but will add 125 rms to each soon. I can't wait to hear what they will sound like then. I've owned Boston, JBL, and Alpine and these blow them away with clarity. Strongly recommended.

6.5 componets

very clean sounding speakers , I always heard good things about this brand but never owned any but they do sound dam good and they are build to last

pure music

this is as simple as it gets if you like clean sound with strong midbass get these cross over 80-100hz 12-24 db slope depending on power applied im running active with 75x4 and to me its plenty. if you want total clarity and accurate music detail get the xs65 components. i have heard alot of components in my life and these really bring the music to life with clarity,detail,staging,imaging and total musical accuracy and they do have midbass, despite popular belief i did find that in my setup the xs65 work better with a hi pass filter on the midbass around 3-4khz 12+db octive i cant say enuff about these buy either one and youll have great sound at a great price

great value.

I like this sound deadner, before I would use peel and seal in my doors but got fed up with the thiner material so I bought this. I have used it in different cars, family and friends and my own and I like how easy it is too cut, and apply. Its tacky but not tacky enough that if you accidently stick it in the wrong spot you cant remove it. I also use the nvx roller which makes it allot easier to apply then just by hand. Iv had mine installed in my doors and trunk for over two years in the northern cali weather and still running strong without that nasty odor people think deadner has. Over all i would reccomend it to anyone looking to improve their midbass and stop those trunk rattle vibrations at a good cost.

Well Made & Good Value for the Price!

There's several manufacturers to choose from when it comes to dampening material these days. I have a hard time believing any specific brand is better than another, outside of knowing I want something that is on the thicker end AND with aluminum siding. I found there with NVX's product and it seems to offer more material for the price. I installed on the rear quarter panel of an SUV and it does work well! Thanks!

By Anonymous on June 27, 2019 Verified purchase

Perfect!

Easy to cut and install! Sticks and molds well everywhere I have used it! It really works!! Thanks!!

Thick! Great product

I installed first on my rear wall, in my truck. INSTANTLY noticed a sound difference after installed. Truck sound was tighter and road noise was cut down too. Very impressed.

By Dustin on March 22, 2018 Verified purchase

Amazing features and sound!

The sound quality is the best I’ve had in my car/s while the adjustability if the crossovers give me adequate fun time when setting this up. This won’t be your traditional component install, at least for most; you are able to adjust crossover frequency, slopes, and gain, amazing :) I wish I had time to install an amp too to see how much louder they’ll get. They are currently getting factory amplification.

Correct install kills the rattles

Enough product to do my whole car. Rattle problem solved.

The only choice

I've been using this stuff for years. Extremely good adhesive and thicker than competitors. I won't even consider another brand.

By Andrew on September 15, 2020 Verified purchase

Best Price at 90Mil Thickness

I shopped all over for good prices on decently thick, quality deadener, and found this to fit the bill. I was not disappointed by the quality of the product, and the results were as expected. Just make sure the material is warm before applied, or it doesn't form as nicely.

Amazing!

These are excellent quality sound damping panels. Easy to cut and apply. I did not use much on my door panels. Only where cables could possibly rattle against the frame and applied some on the frame behind the speaker. What a difference It made with sound level and bass. My speakers sound loud and clear.

By Marco on June 5, 2022 Verified purchase

great

Like the other NVX products its a great value and works well. Sticks great and doesn't smell like some other products I have used in the past.

By James on March 7, 2018 Verified purchase

Awesome

I installed these speakers in a 2013 Silverado with the Metra adapters. The key to getting good sound out of these is proper installation with plenty of sound deadening. These speakers are very large and need plenty of mounting depth to allow for a proper seal. The tweeters have an insanely large surface area and may not fit most stock locations. I installed 40 sq ft. of NVX deadener per door and 6.5" foam fast rings to help dampen the vibrations from the midbass and help direct the sound. The tweeters are mounted in the sail panels. They are running passive bridged on channels 1 & 2 and 3 & 4 on a JL XD 600/6 crossed over at 80 hz and they sound amazing. I have plans to ditch the crossover and run active with a DSP, but for now the crossover works fine. The midbass is strong and the tweeters are crisp without being harsh like aluminum. If you are not installing the midbass driver on or within 1 ft. of the tweeter, you need to read the manual and switch the crossover jumpers appropriately. When the tweeter is further from the midbass, the tweeter needs to be crossed higher. While these speakers have excellent midbass, they are not subwoofer replacements. I hope Image Dynamics has plans to switch to push connectors for the next generation because it is difficult to find spade terminals that fit the positive connection, the provided ones are too small unless you bend them. Also, the crossovers do not accept wire much larger than 18 awg. I used knukonceptz 12 gauge in my installation and had to install bullet connectors to fit enough wire into the crossover.

Awesome!

Best set of components ive owned!!! Which have included hertz,morels,kicker,alpine and crescendo. Overall great balanced sound !.. Powered by a PPI P900.4 probably seeing 125 watts set with the dd-1...Tweeters are not bright non fatiguing and mids are perfect!. Overall the set is well balanced for all types of music. I will take away one star for the connections on the crossover which is a pita!. requires like 18 gauge maybe 20 or smaller wire .. I prefer the screw type like most sets i've owned have because i run 16 gauge OFC either way it worked. Many crossover points for the tweeters and level adjustments which is a plus. I set mine as per recommended for A pillars other than i set the tweeter attenuation at -2db. For $160 i paid for these there's nothing out there that can compare. This set is staying installed for a long time. Sonic has great service and speedy shipping!

Awesome sound!

These speakers sound awesome! Life like and pretty loud. Ordering and shipping went as smooth as you could want. Overall great experience.

Excellent

If you're on the fence about this stuff vs dynamat look no further , do yourself a favor and get NVX , every bit as good as the other with a better price point .

Good stuff.

Easy to install. Not thin like some of the other products I have used. Very good price for the product.

By Roger on March 12, 2022 Verified purchase

Great Speakers

Love these speakers. The install went well, but be warned they are deep for a lot of doors. So make sure you can fit a 3 inch deep speaker. They sound amazing right out of the box and even better with my dsp setup. I used these to replace and old set of diamond hex's that cost twice as much and these sound much better.

By James on March 7, 2018 Verified purchase

Definitely an upgrade

First set of aftermarket speakers I have bought. It is night and day compared to the factory JBL system in my GS300 and even the B&O system in the A4. The tweeters are too big so factory location (door sail) is not usuable; which turns out to be a good thing. Using them in a coaxial setup, default crossover settings, the imaging is improved significantly. Music sounds more lively, each different sound is more noticeable as if headphones were used; with a wide soundstage on the dash. I must say the way they have soldered the 22 gauge wires on the tweeters scare me. I feel they will come apart if you wiggle them too much during installation but luckily they did not. Other than that and the flimsy looking spade terminals, build quality is fairly nice. Oh right, had to clean out the threads on one woofer to get the tweeter to fit on properly (probably some paint or gunk on threads). Mid woofer mounting required a 0.5" spacer for my GS300. Mind you this is still a preliminary setup powered off a headunit. Mids are there, vocals are a lot stronger than stock speakers but definitely needs more than 10wrms. Doors have been deadened with NVX deadener. Will be purchasing a pioneer headunit with T/A and probably some RTA tuning for this to sound even better than it already is. Would definitelt recommend this to people who want decent audio in their vehicle.

ID CXS64V.2

Bought these to replace Polk DB6501's. Good speakers, but not what I wanted.
These ID's sound amazing! Highs are bright & crisp, & mid's are just where they need to be.
Really impressed with the sound quality of these speakers.
If you have the room to mount these, go for it. You will not be disappointed. I'm Sold on Image Dynamics products.
Price is not bad, either.
Sonic Electronix are easy to deal with & quality products.

These are the best performance speakers you can buy for $230 right now!!!!!!!

Wow when i bought these speakers they were 320.00 a set and i thought they were worth that money and now they are 230 wow that is a steal of a deal if you ask me! I have had plenty of high end systems and let me tell you that these are on par with any of the seakers costing at least 2 times as much!!! At this price its a no brainer!! I have these bi amped right now an they sound amazing they can take the wattage they claim and more as long as you know how to set the crossover points!! i am very pleased with the tonal accuracy and sound stage they produce!!!! they put out enough midbass at lower volumes but as you raise it to 125 watts for the 6.5 and 100 watts to the tweeter you should crossover at 100hz with a 24db slope and you will be rocking them!!!! They sound great enough to enter into the competition with!!! Enough said buy these and you wont regret it!!

Awesome sound with unfortunate planning

First off, absolutely incredible sound for the price, and as a home theater enthusiast, I've heard some pretty expensive speakers on some pretty expensive amps. On an equalizer with a little tweaking, forget about it, quite the impressive clarity at a very exceptional price, although I do have a few gripes.

I absolutely did not like the plastic encasing on the tweeters, same goes for the mids, the baskets on the woofers ARE PLASTIC... like... seriously? at this price? It's something I would expect out of something less than $50, but when you slap a $380 price tag on something, I would at least expect aluminum baskets on the woofers, which even cheaper brands like boss has stamped aluminum. I tore up the back of one of the tweeters because the grill was cross threaded, so, warranty voided. Second, the tweeter leads, the oh so thin leads leading to the tweeters are hard-wired. I understand why they did this, because they can be used as coaxials if you so please, but if you make 1 too many mistakes and cut those wires too short, you're gonna have to buy new tweeters, because guess what? they're press fit into the flimsy plastic, so good luck soldering new leads without tearing up the diaphragm.

I guess now that I'm putting thought into it, and typing it, it's safe to say that the tweeters are what made the execution of an otherwise fantastic sounding set of components a HUGE buzz-kill, but at least the crossovers are protected by good aluminum, which leads me to my next point. It took a little prying, but I was able to get the covers off the crossovers to adjust the settings. Many other manufacturers tend make these settings adjustable without having to pry apart their very expensive equipment. It's a very good thing I'm a DIY-er, otherwise I would have returned these because I would not have been able to put up with the headache the tweeters and crossovers have caused.

On another note, that little bag of goodies can simply be tossed. If you don't already have solder, a soldering iron, and flux, get you some of those because it's a lot more quality connection. And I have no idea what that allen key was for, because it was too small for the screws on the crossovers, which is what i though it was for, but it wasn't. And none of the screws in the bag are hex, they're all philips, so way to go image dynamics.

I payed $270 for this set, and I think that is THE absolute max I would have payed, given the plastic woofers baskets and tweeter frames. Plus here is an even bigger middle finger, the tweeter to woofer connectors are aluminum, as well as the bullets that cover the pole piece when they're being used as components, those are at least aluminum, and probably the most durable parts of this entire system. I can imagine the woofer baskets cracking in cold weather.

Had I designed these, I would have made the tweeter to woofer connectors with a hole on the side to route the wires through, thus granting the ability to solder new leads if ever required

Excellent products at the best prices.

Better and thicker than Dynamat

It’s a no-brainer; this brand of sound deadening is the best for what you pay for. There are no drawbacks for this cheaper option.

By Martin on May 17, 2024 Verified purchase

Thick and shiny

This stuff is heavy duty. I have no doubt this stuff is going to help on my doors. I love the shiny top, even though you can't see it once installed it looks good coming outta the box. Would def recommend this product along with any other NVX product. Have been using NVX for over 5 years and their products have never let me down
