Speaker Specifications

Series
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.
Pair
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.
5-1/4"
Design
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.
Dome
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
1"
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.

Silk
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.
Polypropylene
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.
260 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.
130 watts
Sensitivity
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".
85 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).
80 - 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.

No
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.
1"
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.
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)
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

March 6, 2014

i have recently purchased and installed this kit so i figured a review would be worthy for this.
upon opening the package i couldn't help but be amazed about how much it weighed for just a 5 1/4 component kit. the magnet on the woofers have a lot of weight. the tweeters you can really see the quality in them its really hard to explain just buy a nvx tweeter and you'll see. the cross overs are clearly labeled and make for a really clean install. upon hearing them in action i was blown away the mids sound punchy as heck some times i feel like i have a set of decent ten inch woofers in my door and the tweeters are loud as heck thanks once again sonic and nvx i truly am not ashamed of this purchase.

Good price

December 26, 2014

I bought to replace my 1999 oldsmobile eighty eight stock component speakers. When I purchased I hadn't yet taken off the door panels to look at old speakers, I just used the speaker fit ode here on sonic electronix to find a pair that would fit my car. Well what I didn't realize is that the old tweeters had a very specific bracket which the nvx set did not include. This set of nvx seems to be more towards custom tweeter installs with options to mount flushed or exposed.Anyways, I was worried at first because Id spent long enough deciding what to buy and at this point justwanted to hear the dang things! I ended up using the thickest duct tape I've ever owned to hold me down, and once pressed up against the door they didn't make a rattle or move so it seems to have worked. The woofers on the other hand screwed right in. Overall I am happy with this buy and would recommend them

took a chance

December 16, 2014

I took a chance on these based on their reviews, i usually would buy a big brand but these seemed legit. I bought these and the nvx 6x9s. After hooking everything up it sounded pretty good but it was just my crappy head unit powering them, so when i bought an amp wow these things came to life. my whole truck is rocking now!

Bright, but worthy - especially for the coin

November 23, 2015

My first impression of this kit is that the tweeters are way too loud and bright. However, using the -3dB attenuation on the crossover helps quite a lot. I discovered that using the swivel in the flush mount option to point the tweeters at the windscreen made a world of difference & did wonders for staging. If your only option is to aim these tweeters on-axis or close to on-axis, you'll want to choose another kit. However if you have the room/configuration to aim them forward, or significantly off-axis, they sound great.

The woofers sound quite good, but really need an amp to get them off their butts. Sound quality is realistic, midbass is present, but not overwhelming...well balanced.

Don't expect to use the included clip nuts as every one I tried snapped in half. I just re-used factory hardware where possible & some drywall screws in my homemade adapter

Other than that, the drivers & crossovers are well-designed and executed & should make most happy - again as long as you amp them & move the tweeters off-axis. Reflected seems best so far with the tweeters. On-axis is too harsh.

I'm still tuning and will be for some time to come, but for the coin, and particularly after re-aiming the tweeters, I'm quite happy with this set. Solid construction, poly cones & butyl surrounds should mean a long, happy life. Considering price (and the huge discounts currently available), these little numbers earn themselves 4 stars.

Great component set

November 9, 2015

The component set is well made and shows there was a lot put into the design and workmanship. Tweeters were overpowering which may be explained by a higher sensitivity level than the woofer. -3dB attenuation was possible via crossover control. Mounted crossover behind door panel (not in door chamber) using high temp velcro tape. Currently running off an Alpine powerpack (45 watts RMS) and feel like it still isn't enough power. You could probably run 75 watts RMS to these. The tweeters are large, but tweeter installation was made easy via supplied mounting pieces. Tweets went in door sail panel in '05 accord coupe. High frequency presence was much improved over stock system, however midrange was where I expected more improvement. After installing proper adapters and nvx sound dampening, midrange was improved, but still not as good as wished for. Maybe more power and sound deadening is needed. I plan to seal off the door shell later on to create a speaker-box-like chamber to improve mid-bass. It would have been nice to have a higher sensitivity for the woofer, but this was a true bargain at the price paid.

Tweeter in the flush mount pod were larger than expected. Crossover does a nice job is at the right frequencys and mounts easily. Haven't had a chance to use the 5.25 drivers yet because I paired the tweets & crossover with X series 6.5 mid driver.

great sound

November 24, 2015

can be harsh at times or bright. over all for the price point its hard to beat. im sure sonic has some other stuff for sale by a more known brand but nvx has some great people working for them and a great product. as for a budget sound system. looking to just upgrade some speakers spend a few extra bucks and get components. nvx is well worth your money.

these came in a car i got in trade and they sound good on a ppi amp. didnt have long with them but when i looked them up i did expect the price to be about 20 bucks more

I've been hearing and reading a lot of good things about NVX. The videos on you tube were as close as I could get to hearing what they sound like. They sound really good in the videos. These will be paired with NVX VSP 6X8 and amp to Hifonics Brutus 320.4. I'm replacing MB quart PVL 268's with all NVX. My MB Quarts didn't make the cut.

the woofers are rated 45 rms and tweeters 20 rms what power do you recommend? I also want a mini amp for easy installation was thinking clarion mini or kenwood mini?? because the nvx mini is a lil outa my budget.
JEROMY A M on Oct 12, 2015
Best Answer: 50 watts rms would be more than sufficient from those mini amps (obviously 65watts rms would be best though). I doubt you would notice a difference of just 15 watts. I have the NVX MVPA4 in my Subaru with this NVX VSP525KIT and the Clarion XC1410 with some Rockford Fosgate components in my my friends Jeep. They both put out amazingly CLEAN and LOUD sound. Haven't had a chance to see the Kenwood in action, but my friend chose the Clarion XC1410 over the Kenwood because the price was basically the same and the Clarion put out 50 watts rms ( not 45 like the Kenwood) and can do 75 watts at 2 ohms and has a selectable high pass filter.

If you just need a good amount of power for the speakers, the Clarion XC1410 would do the job extremely well. For the price and size of the unit, you will be surprised.
If you want more control over the amp and more features, I would go for the NVX MVPA4 if at all possible.

Both would be a good choice, and they were pretty simple to install too as long as you know what you're doing of course.

Sorry, can't speak for the Kenwood since I have no experience with it. Good luck choosing.
