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.

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.

Good price

I bought to replace my 1999 oldsmobile eighty eight stock component speakers. When I purchased I hadn't yet taken off the door panels to look at old speakers, I just used the speaker fit ode here on sonic electronix to find a pair that would fit my car. Well what I didn't realize is that the old tweeters had a very specific bracket which the nvx set did not include. This set of nvx seems to be more towards custom tweeter installs with options to mount flushed or exposed.Anyways, I was worried at first because Id spent long enough deciding what to buy and at this point justwanted to hear the dang things! I ended up using the thickest duct tape I've ever owned to hold me down, and once pressed up against the door they didn't make a rattle or move so it seems to have worked. The woofers on the other hand screwed right in. Overall I am happy with this buy and would recommend them

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!

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

NVX SDBSK2 Premium Stealth Black

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

Good product

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

took a chance

I took a chance on these based on their reviews, i usually would buy a big brand but these seemed legit. I bought these and the nvx 6x9s. After hooking everything up it sounded pretty good but it was just my crappy head unit powering them, so when i bought an amp wow these things came to life. my whole truck is rocking now!

incredible.

i have recently purchased and installed this kit so i figured a review would be worthy for this.
upon opening the package i couldn't help but be amazed about how much it weighed for just a 5 1/4 component kit. the magnet on the woofers have a lot of weight. the tweeters you can really see the quality in them its really hard to explain just buy a nvx tweeter and you'll see. the cross overs are clearly labeled and make for a really clean install. upon hearing them in action i was blown away the mids sound punchy as heck some times i feel like i have a set of decent ten inch woofers in my door and the tweeters are loud as heck thanks once again sonic and nvx i truly am not ashamed of this purchase.

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.

NVX SDBSK2 Premium Stealth Black

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

Great value

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

Great product, Sonic Electronix is great. I've ordered a few things from time to time and have had no problems. I get the item quickly. I ordered this and was so pleased. I ordered another set. Works great.

Great Value and Sound

I put this set in my 83 F-150 with a older Sony 100.2 amp. Sound good, very clear and they make my door mirrors vibrate. I feel I got my money worth and then some. Highly Recommended!!!

Great fit

I bought these with the 6x9's as well they're such great quality and have amazing sound easy to install fit so good I was able to use all factory parts to install them! Great quality at an even better price thanks sonic!!!

Buy now

NVX has a new customer for life. Good shizz. Buy them now. Amp or no amp they are beautiful! Yes beautifully loud and appearance wise. Quality.

great price.

speaker out performed my expectation at great price highly recommended.

Bright, but worthy - especially for the coin

My first impression of this kit is that the tweeters are way too loud and bright. However, using the -3dB attenuation on the crossover helps quite a lot. I discovered that using the swivel in the flush mount option to point the tweeters at the windscreen made a world of difference & did wonders for staging. If your only option is to aim these tweeters on-axis or close to on-axis, you'll want to choose another kit. However if you have the room/configuration to aim them forward, or significantly off-axis, they sound great.

The woofers sound quite good, but really need an amp to get them off their butts. Sound quality is realistic, midbass is present, but not overwhelming...well balanced.

Don't expect to use the included clip nuts as every one I tried snapped in half. I just re-used factory hardware where possible & some drywall screws in my homemade adapter

Other than that, the drivers & crossovers are well-designed and executed & should make most happy - again as long as you amp them & move the tweeters off-axis. Reflected seems best so far with the tweeters. On-axis is too harsh.

I'm still tuning and will be for some time to come, but for the coin, and particularly after re-aiming the tweeters, I'm quite happy with this set. Solid construction, poly cones & butyl surrounds should mean a long, happy life. Considering price (and the huge discounts currently available), these little numbers earn themselves 4 stars.

Great Sound!!!

Great Sound No Doubt! It was tricky to run wires back & forth thru the car to crossover but very worth it at the end! You won’t regret this buy made my Bose system sound pathetic.

By Jeffrey on February 16, 2020 Verified purchase

Top notch

I had my Doubts about NVX but I can say this is some of the best car audio I have had it is in my opinion very close to JL audio.

By kevin on March 19, 2018 Verified purchase

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.

Sound deadening

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

NVX SDBSK2 Premium Stealth Black

Perfect fit an very fast shipping.Good list to choose from to fit my car.

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 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

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

Does the Job

Great Bang For the Buck

Speaker is awesome decent mid-bass for a 5 1/4 super-bright highs great for the pods I had. Couldn't beat the quality for the price!

By Ben on March 24, 2020 Verified purchase

Great treble

I haven't had the opportunity to test the bass from the woofers, but the treble from the tweeters is crystal clear. Very good quality from this kit, especially considering its price point. I especially like the included tweeter pods with their multiple fitment options.

By Cameron on December 16, 2016 Verified purchase

Great product

Easy to install and sounds great and would recommend buying this product.

Great component set

The component set is well made and shows there was a lot put into the design and workmanship. Tweeters were overpowering which may be explained by a higher sensitivity level than the woofer. -3dB attenuation was possible via crossover control. Mounted crossover behind door panel (not in door chamber) using high temp velcro tape. Currently running off an Alpine powerpack (45 watts RMS) and feel like it still isn't enough power. You could probably run 75 watts RMS to these. The tweeters are large, but tweeter installation was made easy via supplied mounting pieces. Tweets went in door sail panel in '05 accord coupe. High frequency presence was much improved over stock system, however midrange was where I expected more improvement. After installing proper adapters and nvx sound dampening, midrange was improved, but still not as good as wished for. Maybe more power and sound deadening is needed. I plan to seal off the door shell later on to create a speaker-box-like chamber to improve mid-bass. It would have been nice to have a higher sensitivity for the woofer, but this was a true bargain at the price paid.

Nice

Very impressed with the sound and quality of these speakers, Pushed them a little too far until I got my amp's set up right, they still ROCK !!

By David on June 29, 2017 Verified purchase

Great sound for the price

Amazing sound for the price

Cons.no cover to protect the speaker if mounted at foot level

great value

Tweeter in the flush mount pod were larger than expected. Crossover does a nice job is at the right frequencys and mounts easily. Haven't had a chance to use the 5.25 drivers yet because I paired the tweets & crossover with X series 6.5 mid driver.

Nice set

Great for a starter component system. Great price, happy with the sound.

A Great Value buy

Speaker kits fits my Dodge 2005 Ram 3500 4x4 really easy to install and sound Great hook up to Nvx 4chanel amplifier 50 watts per speaker sound a little pushy and cross over easy to install and hook up and soft dome tweeter sound great I would definitely buy again.

NVX Top Quality

Clean And Crisp For A 5 1/4 Woofer, And The Tweeters Are On Crack! I Bought Two Pairs To Try Out...If Your On A Budget Buy These. If You Want SPL Though Go With The X-Series(AMAZING!). Great Job NVX!

By Bryson Customs on April 28, 2016 Verified purchase

great sound

can be harsh at times or bright. over all for the price point its hard to beat. im sure sonic has some other stuff for sale by a more known brand but nvx has some great people working for them and a great product. as for a budget sound system. looking to just upgrade some speakers spend a few extra bucks and get components. nvx is well worth your money.

these came in a car i got in trade and they sound good on a ppi amp. didnt have long with them but when i looked them up i did expect the price to be about 20 bucks more

Sounds great in my jeep

These handle lots of power, sound great. I was disappointed that they do not come with grilles, however. I had some old Polk grilles I put to use. Very clean sounding speaker!

By Bayslayer on March 12, 2023 Verified purchase

Good for the price.

Decent speakers for the price. The highs are crisp, can't handle a ton of bass, but I didn't really expect them to given the size. Overall not bad. Might want to spend a little more for something with more range, but for this price they can't be beat.

Best stuff on the market

For the price this is the best stuff by far out there A+++++

By erik on December 21, 2024 Verified purchase

Good little component set

I have these on a 100 watt rms per channel amp. They sound pretty good for the money but will distort when you really crank the volume up. I wish they would go just a tad bit louder before distorting but for what they are I'm pretty happy with them.
I put these in my daughter's buick regal with only slight modification to the tweeter area in the door panel they fit great.
