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.

good speakers

The following review is for NSP46, which is a part of the bundle you are viewing.

I got 2 sets for my 1988 silverado and they fit with no problem and they sound real good and they look good.

Nice speakers for the price.

The following review is for NSP46, which is a part of the bundle you are viewing.

I bought these to replace the stock, blown dash speakers in a 94 Chevy 1500. They are a little too tall for the speaker grilles to sit flat (the tweeter sits above the speaker about 1/8"), and they slightly interfere with the passenger side defroster vent tube, but that's universal fit for you. They sound good considering they're powered by a stock 20 year old am/fm radio though. I would definitely recommend them as an upgrade from stock speakers.

Great Speakers

The following review is for NSP46, which is a part of the bundle you are viewing.

I have a pair of these in my 2003 Cavalier, they bolted right into place, and they sound amazing! Running off headunit, these and my 6x9 NVX speakers in the back make a huge difference over the original speakers! Very impressed with NVX, and will continue to buy their products

Sound great

The following review is for NSP46, which is a part of the bundle you are viewing.

They really made a great replacement for the stock speakers that go in the dad of a 2000 chevy blazer, and they are cheap, which was a plus. They are also low watt so you can run them off just a head unit.

good for the money

The following review is for NSP46, which is a part of the bundle you are viewing.

They're not gonna blow you away, but they're nice replacement speakers for the money. Just don't expect them to keep the bass coming when you really crank em. Start to distort. Good sound quality at medium to low volume though. nvx (aka sonic elecronix[yes they own nvx]) makes pretty good stuff.
