Power and Value with N-Series

NVX's entry-level subwoofer is anything but "entry-level." NVX has engineered the NSW104 with exceptional features, such as a polypropylene cone, Nomex single spider and a high excursion rubber surround. This all adds up to a sub that moves more air for awesome, responsive and deep bass. The 2" dual 4-ohm KSV voice coil gives you a wide array of Ohm load wiring options for different applications. With an RMS Power Range of 200-350 watts, the NSW104 requires less power to operate efficiently without losing bass quality.

Continuing with the excellent engineering is a stamped steel basket that provides exceptional rigidity and the spring-loaded, chrome plated push terminals ensure a strong and dependable speaker wire connection. NVX's mission was to create an exceptional subwoofer at an entry-level price without sacrificing the quality and sound that the consumer deserves. They have succeeded!

Additional Information:

*CEA-2031 Compliant: All CEA-2031 compliant loudspeakers adopt the same testing and measurement methods so comparing them side by side is easy. Loudspeakers include car speakers and subwoofers. The Consumer Electronics Association created new testing and measurement methods for mobile loudspeaker systems that define test procedures for rating the performance and physical size of speakers. This is important because you can now compare different speakers on the same playing field. Any manufacturers who adopt the CEA-2031 logo product mark can be compared evenly to other speaker manufacturers with the same mark.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
N-Series (NVX)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
10"
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.
350 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Dual
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
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
2"
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).
20 - 200 Hz
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".
83.4 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
8 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Black
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.
Rubber
Magnet Structure
Defines the overall structure of the subwoofers magnet.
Single Stacked
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
No
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.0 cubic feet
Optimum Ported Box Volume
This value indicates the ideal ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.5 cubic feet
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.
4-11/16"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
9"
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

Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
36 Hz
Equivalent Compliance (Vas)
This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
24.96 liters
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
0.66
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 10.
0.818
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
6.40 ohms
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 10.

Top-notch quality and fantastic performance at a budget-friendly price

June 12, 2014

I chose this entry level NVX subwoofer for my latest build due to the low cost, great reviews, and it fit the specs I was looking for. The construction, materials, and overall build quality of this subwoofer left me seriously impressed. I have three of these NVX NSW104's in a custom designed/built 3 cu ft sealed enclosure, each sub has the coils wired in series (8ohm load each) and all three subs wired in parallel resulting in a 2.7(ish) ohm load pushed by a JL 1000/1 amplifier. After correctly setting gains using an SMD DD-1 (highly recommend purchasing to prevent damaging any of your equipment from clipping), the end result is absolutely astonishing! When the sub channel is set at a reasonable level (minus 18 or so db on the HU) it is an extremely quick responding, tight, punchy bass with some serious authority to it; However, when I crank up the sub output to -3db or so, it is so incredibly impressive that when demo'ing the system to people they lose their minds when they discover it's not a couple of JL W7's in a ported bandpass, especially when they see the windshield flexing. Everyone has called me an outright liar when I tell them how much I paid for all three subwoofers! I have and will continue to highly recommend the NVX product line-up to anyone and everyone who inquires. From their battery terminals to their subwoofers - top notch quality and fantastic performance at a budget-friendly price, what more can you ask for?

Especially for the money... awesome little sub!

August 11, 2014

Got these subs actually for a customer short notice to throw in a truck box under his seats, ended up not getting them install day so used a couple others till these arrived...and actually said hey why not, I'll use them in mine. We're used to a ton of different subs. For a $100 range for BOTH subs shipped, these little monsters surprised me, putting them on 600 Rms. Have 2 wired down to 1 ohm On a Crescendo 600.1 Now, Obviously don't expect these to take 1000w a piece and kill big boy 2.5"+ VC subs. But wow, under seat box about 1.2cu.ft a piece ported at 34-35hz and theyre actually shaking the windows and playing with authority down to about 28hz. Highly recommend them for any intro system, surround is tough rubber and cone looks great. Would buy again for $50 shipped any day of the week. Would even more so love to put them on 4-500w a piece see how they like it.

Great Entry level sub

July 26, 2014

I own a 2011 f150 supercrew and I installed these in a box that fit underneath the backseat. I had about .7 cu.ft. of net air space. The subs sounded good. I could tell immediately that they needed to be broken in. I would give them a couple of weeks to break in until you really get as much audio quality out of them. For 50 bucks each they are a great value. NVX makes great car audio equipment. But don't expect to be blowing your windows out with these subs. These are definitely not competition grade subs, I guess nor are they advertised as that so.... but to enrich your sound in your car in a tight space saving install these are excellent. Over the years however I am starting to lean more towards paper pressed cones. I find they have a better handling and a little more accurate of a sound. I would definitely recommend these for a budget build with quality in mind.

nvx104

March 18, 2014

Purchased 4 nvx104 placed in custom 4 10"box in 87 camaro. Ive had 4 10" kicker comp 2007 edition, 4 10" sony grey stop sign. Comparing the 3 nvx to me sounds alot clearer and hard hitting. Nvx fits perfect for my small enclosure box..ive recommended a few people to order nvx. Considering I do install music and my recommendation means alot to my customers. Cant give full thoughts of subs haven't really maxed out yet but the quality is there for the price

great sound quality

January 15, 2014

This is a great entry level subwoofer it has awesome sound quality it hits lower tones that other subwoofers in its price range can not reproduce. You would be hard pressed to find another sub in the same price range that sounds as good. It features a high surround to provide extra excursion. It looks, sounds and feels like a more expensive sub. It can go reasonably loud with good sq just dont expect this one sub to flex your whole car. I would deffinatly recomend this subwoofer to a friend. I recomend NVX products to anyone that asks me for car audio advice. Shipping from Sonic Electronix is also super fast i ordered my sub and received it the next day. Sonic also has great customer service they stand behind their products 100 percent.

After months of research on this speaker I decided to go for it. unfortunately I don't have it in my car. my Logitech z 5500 sub finally gave up so I made a swap and @ 8 ohms WOW couldn't be happier. So I decided that im gona go with the 15 inch vcw series for my car....two words for nvx. "very impressive"

Great entry subs!

January 25, 2013

I highly recommend these subs for someone who expects quality and great sound from their speakers. I have two of these in a sealed enclosure giving them about .85 cubes each and powered by a Hifonics HFI 1000.1D at 1 ohm and I've measured them getting roughly 350 each RMS and they absolutely astonish me with their output. They're in a 2008 Dodge Caliber SRT-4 facing the rear hatch and they are super crisp and clean sounding, no drool and very snappy. They put out some serious low notes that I did not expect from a 10" subwoofer that's entry level. I replaced my two 10" Kicker L3's with these and I can say they out perform the Kicker's hands down on SQ and SPL, they are almost on par with the SPL of a Memphis 10" C3. Needless to say you will not be disappointed with this purchase as I am very happy for the quality and service I got with these. And as always Sonic came through with unmatched service and crazy fast shipping, I payed for ground and got the whole order in 2 days!
