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.

Great Backfill

The following review is for NSP525, which is a part of the bundle you are viewing.

I purchased these to use as backfill in my NVX system and I am pleased to report that they have met my expectations to a T. They are plenty clear, and handle the power I am throwing at them very well. Like most speakers of this size and design they are limited by how much bass they can produce, but for rear fill in a system they are perfect. My kids say this is a huge improvement over the Bose speakers they replaced.

Great product.

The following review is for 72-5512, which is a part of the bundle you are viewing.

Product does just as described. Would not hesitate to purchase this item again. Metra has a very nice product line with lots of hard to find adapters and cables. Better application listing would be helpful.

Great deal

Originally bought these to put in my vehicle but ended up using them as my center channel in my surround sound system and I'm not disappointed they sound great

Great bang for the buck

The following review is for NSP525, which is a part of the bundle you are viewing.

So far, NVX hasn't let me down with anything I've tried. While these speakers certainly aren't "audiophile" quality, they are without a doubt better than anything I've ever heard in the same price range. I have them running off of an average power H/U with no amp and they still supply plenty of clear volume.
