NVX VSP60 with Sound Damping

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.

Impressed! But Not At First Listen! Loud doesn't equal qualtiy!

NVX is a relative new comer. I did a lot of research prior to selecting these speakers. I also purchased the NVX N series 6x9. The rears are 55wt each rms with a frequency range of 70hz. The fronts 6.5 are 50wt each rms with a frequency range of 58hz. An important factor with a 4ohm speaker with a sensitivity level of 89db. I wanted this change because I thought the lower frequency range speakers I had in this Cobalt were a little to base heavy which overwhelmed the front at 48hz. Acoustically for this type vehicle was a little much imo. The speakers kicked pretty hard even at 2db on the low. I attributed this to the car being a compact, and not as heavy as road car like the Impala, or Malibu. This car has HU with a parametric EQ, and an Alpine 445U power pack with 45wt per channel. With this I can deliver 95% power to the fronts, and 90% to the rear. The sensitivity levels on both the front and rear are in equilibrium at 89db, This balances the fade.
The sets that were removed in the rear were 87db with the fronts rated at 92db. At first I thought I wasn't going to like the speakers, and perhaps I had made a mistake with the change, but I was tired the first evening, and the change I thought was pretty dramatic that speakers were to bright, and maybe to quiet to what I had become accustomed to, but not the second. These speakers are not to bright, and aren't as quiet as I first thought. The reverberations in the car were gone, the boomy sounds had dissipated, and what I was left with were very crisps clean sounds without doing to much to the EQ, A little adjustment here, and there, and I could hear the faintest of sounds. Again I would like to point out that this HU has a parametric EQ which allows for adjustments from -2 narrow to +2 wide ranges for the low, mid, and high. I was happy to discover that I could adjust the low to a -1 narrow imo sounds cleaner. It didn't work with the prior speakers, and produce a good clean sound. We don't like our hears to hurt, and to enjoy music in a normal listening range the Loud button on high did the trick, it added the depth I wanted to hear. There is no subwoofer which I prefer. Playing music loud with all the thumping for me can be annoying, and to loud will cause the ear drum to distort if not the speakers Good quality speakers produce the sounds of every instrument cleanly and naturally at low volumes. These do just this. Powering up with just a small in dash amp brings out the full potential of these speakers. Trust me when you take them out of the box you will discover the quality that went in to making these speakers, in this catergory second to none. NVX has a full line of speakers and equipment for the more enthusiast, I am a avid music listener. Good music deserves decent equipment to be able to appreciate it. Hope this review helps. I even went as far as talking to Brian at NVX, and found him to be very nice and more than willing to give me his time with all my questions prior to making the purchase. I hope NVX much success. I personally am very satisfied.

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.

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.
