Priced Per Complete Component System: 2 midwoofers, 2 tweeters and 2 crossover networks.

Speaker Specifications

This is the manufacturer product line of speakers.
V-Series (NVX)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
6-1/2" (also mounts in 6-3/4" w/ included brackets)
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
2-way Component System
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Nitrile Butadiene Rubber (NBR)
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
280 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
140 watts
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
88.50 dB
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
70 - 20000 Hz
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
Optional (Accessory Required and Sold Separately)

Thought that for the price it was worth it to take a shot on this company that is getting rave reviews
Thomas F on Apr 9, 2016
I am a big EXOcontralto fan and feel that his approval of NVX gives me all the confidence I need to try them out. I have been an MTX fan for a long time but I feel that their quality has gone down hill for a while now. Maybe it always has been, but either way I am confident I will like these. I have heard them in an SQ build and they did sound excellent. I wont be running a processor, so I am not expecting the same results. These are the start of a full NVX system.

do I need an amplifier for this?
A shopper on Aug 12, 2014
Best Answer: Short answer: Yes

Long answer: Technically, every speaker needs an amplifier. While the amplifier in your head unit can provide some power (it likely outputs 15-25 watts (RMS)), which is quite a bit shy of the manufacturer's recommendation of "70 watts each side" (RMS). And while these speakers will make noise with fewer watts, they won't sound as good. And it will be noticeable. Personally, I always recommend meeting, or (very) slightly exceeding, the manufacturer's suggested power rating. That typically requires an external amplifier.

Crossover switch for 0/-3db location ? didnt see it in pictures
A shopper on Aug 20, 2015
Best Answer: I purchased these speakers a while back; but, I used an active crossover system through my JBL MS-8 signal processor. So, I'm not 100% positive; however, the crossover switch for 0/-3db can often be found inside the crossover unit for most component systems that offer this type of control. Simply pop off the cover and there should be a switch or a jumper that can be moved from 1 set of pins to another set of pins to adjust the db.

I understand that the tweeters on this setup can be flush mounted, but how? I keep looking at the pictures to see any hardware that can help them stay in place if they are flush mounted to a door panel but I don't see any hardware that can hold it.

For example, the Alpine SPS-610c has a screw on base. So basically make the hole big enough and lock it in my screw it in. But how would you accomplish this with the nvx?
Brian S on Sep 16, 2014
Best Answer: The cover surrounding the tweeters in the stock pictures is the flush mount hardware. It basically separates into three parts. The lower and upper case and then a mounting ring which you just force onto the back of the case to press against the top flange and it holds against it basically just with a friction force. I didn't have any extraordinary difficulty mounting mine. I used some cardboard and mounted the tweeter to it and then screwed that into the existing cutouts for tweeters in my dashboard.

I hope this helps. I haven't had any issues with mine since installation.

What is the crossover frequency set at?
Jason C on Dec 16, 2014
Best Answer: According to the NVX staff answer below, it is set at 1500hz. I own a set of these speakers. I can tell you from experience, I'm running these components with an active crossover system, that 1500hz is way too low for this component set. When amplified at higher volumes the speakers get really muddy and distorted. I played with my x-over frequency for quite a while starting at 3500hz and moving up little by little to 4500hz. I can definitively state that the speakers sound much better at 4500hz than they did down at 3500hz. They are still a bit off though. I plan to raise my x-over frequency to 5000hz in the near future to see if it sounds better.

will this fit on my vw jetta 2000?
A shopper on Mar 31, 2016
Best Answer:

Our fit guide is correct, 6.5" speakers will fit your vehicle. The tweeter may need help fitting properly, but your installer will handle it accordingly. If you plan on doing this install yourself, we highly recommend doing your homework first and also picking up the Scosche SAVW6.
