Redefining “Entry Level”

Don’t just replace your speakers – upgrade them! At NVX, we set out to build an affordable speaker solution for audio enthusiasts on a budget; although priced to compete with other “entry-level” speakers on the market, the N-Series offer sound quality and reliability which blows the competition out of the water. The materials and designs used in the N-Series were carefully selected to provide the best possible performance.

A Simple Installation Process for Every Application

The speaker utilizes an integrated filter network, which makes installing these speakers as simple as connecting the wires and mounting them to the door. N-Series is available in 3-1/2”, 6-1/2”, 4”, and 5-1/4” round models, and 4”x6”, 6”x8”, 6”x9” oval models. So if you’re in the market for a speaker that’s more about thrills than frills, look no further than our N-Series Speakers!

Designed & Engineered for Accuracy & Durability

Our speakers are designed with durability and sound quality in mind without having to break the bank. The polypropylene cone material is strong, yet lightweight for accurate mid and low tones. The Nitrile Butadiene Rubber Surround supports the smooth, linear movement for optimal accuracy. The Stamped Steel Basket Provides a strong, sturdy foundation for a durable and long-lasting speaker. The High-Temperature KSV Voice Coil provides superior current distribution with effective heat dissipation. All these materials combined make for a powerful line of speakers.

The Silk Dome Tweeter Delivers Impeccable Clarity

One of our favorite features in the N-Series Speakers is the amazing tweeters. The rich treble in our speakers are reproduced with stunning warmth and smoothness thanks to the 20mm silk dome tweeters. This material is usually reserved for premium component systems, however we are offering this feature in our pocket-friendly speakers.

Frequently Asked Questions (FAQ)


NVX aims for a guaranteed fit across various makes and models. This 6.5" front door speaker replacement package ensures a simple and hassle-free plug-and-play installation with no modifications required.
Yes. NVX's NSP65 are highly efficient, meaning they produce great volume even with the lower power of a factory stereo. However, you'll get noticeable sound upgrades with an aftermarket stereo and amplifier.
You can install this speaker package to some 2003-2013 Mazda Mazda6 vehicles with factory Bose audio systems, but as the factory system yields power at a lower impedance rating, it would provide less power to NSP65 at 4-ohms.
2003-2013 Mazda Mazda6 use 6.5" factory rear door speakers. If you wish to use 6.5" speakers like NVX NSP65, you could use 6x8" to 6.5" speaker adapter brackets to create a secure fit.
You’ll get much cleaner mid-bass punch. While 6.5" speakers can't provide very low frequencies like subwoofers do, the heavy-duty magnets in this kit provide a tighter, fuller low-end that won't bottom out like the worn-out stock drivers.
You don’t need to buy more screws. Aside from your factory screws, NVX also has supplied you with 8 screws and 8 speed clips to help with your installation. There's also no need for extra hardware as the speakers already fit factory openings.
This specific package is only intended to replace factory rear door speakers. However, NVX also offers a 6.5" front door speaker replacement package for the 2003-2013 Mazda Mazda6 (Sold separately).

Great budget speaker

The following review is for NSP65, which is a part of the bundle you are viewing.

I put these in the front doors and some NVX 6x9s in the rear deck on a Cobalt to replace blown factory speakers. They were just running off the (extremely weak) factory GM radio.
I was very, very impressed with their performance for a budget speaker. The tweeters were bright without being too harsh, and the bass response was unreal for the tiny amount of power they were getting from the headunit. Now, they didn't slam like subs or anything, but it was solid bass.
I think it was

Great cheap speakers

The following review is for NSP65, which is a part of the bundle you are viewing.

I just installed these and I'm quite impressed. Clean highs that aren't overpowering, decent mids and much better bass than my stock speakers without distorting. I don't have them amped, I'm just running them off a JVC headunit but they still sound phenomenal with very little distortion at high volumes. I'll definitely be trying out other products from nvx.

NVX 6.5" coax speakers

The following review is for NSP65, which is a part of the bundle you are viewing.

For the price, you are not going to get a better replacement or entry level speaker. Good sound though they do not come with speaker grills/covers so consider that, should you need them for your specific application.

Awesome Entry Level Option!

The following review is for NSP65, which is a part of the bundle you are viewing.

I put a set of these in my access doors in my Frontier a few months ago and love them. I have the 6x9 version in the front doors and am powering them with a MTX 4 channel at 55x4. The mids and highs are crystal clear and smooth. I prefer the silk tweeter on these to other options that have a more shrill or harsh sound to them. Can't speak to the way they sound on deck power or the bass response as they are running on a high pass crossover through the amp. I highly recommend them and the combo pack with a set of these and a set of the 6x9's is what I did. Phenomenal package deal for the value of these speakers.
