Wallet Friendly N-Series Power

The NVX N-Series subwoofers offer top-notch sound quality at an entry-level price. The NSW122V2 is a great multi-purpose sub that has been engineered to meet the highest audio standards. The stiff, ultra-light non-pressed paper cone allows the N-Series subs to give you accurate and responsive low-end even when you have your system blasting. The custom-blended high roll foam surround allows for a greatly improved excursion for further improved sound quality. The 2" dual 4-ohm high-temperature aluminum 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 NSW122V2 requires less power to operate efficiently without losing bass quality.

Continuing with the excellent engineering is a stamped steel basket that provides exceptional rigidity while minimizing any unwanted distortion. The N-Series subwoofers also include spring-loaded, chrome-plated push terminals that provide an easy and secure 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!

1. Rubber Subwoofer Trim Ring Gasket

We’re all about the details here at NVX. That's why we include a rubber trim ring gasket with our N-Series subwoofers. The trim ring provides a tight seal against the sub and the box it is being mounted to, in order to prevent air pressure from passing between the two.

2. Surround & Suspension Technology

We’re all about getting the most bang for our buck, a key reason why we chose to include high-roll foam surround technology in the N-Series woofers. The surround itself is constructed with high excursion foam, which keeps the inward movement of the surround perfectly symmetrical with the outward movement.

3. Custom Stamped Steel Basket

Our custom basket offers several distinct advantages over traditional designs. We purposefully chose an especially open basket to improve airflow to reduce compression of the motor structure for both improved cone control as well as reduced back-wave interference.

4. 2” High-Temperature Aluminum Voice Coil

The stout 2" high-temperature voice coil is constructed from a copper wire wrapped around an aluminum former. This industry-standard design is powerful enough to readily drive the cone with strict linear control, yet at the same time remains efficient enough for the compact, space-saving magnet structure.

5. High-Energy Ferrite Magnet Motor Structure

We chose a highly magnetized single stacked Ferrite magnet for the motor structure in the new N-Series. This magnet allows for greater power handling and voice-coil control during high excursion limits.

6. Ultra-Light Non-Pressed Paper Cone

After testing scores of different cone materials, we decided on a custom blend of fine Ultra-Light Non-Pressed Paper fibers. This stiff yet lightweight material produces spectacularly accurate bass with a rich, natural tonal quality prized by audiophiles. The smooth matte finish of the cone offers a sleek, modern accent to the interior of any car.

7. High-Excursion Strain-Relieved Tinsel Leads

At NVX we understand that the components of a subwoofer must work in harmony to achieve sonic excellence and that a subwoofer is only as reliable as its weakest link. There is perhaps a no better example of our relentless attention to detail than the unique attachment method of our tinsel leads. Whereas the leads of most subwoofers are simply glued atop the spider, ours are glued at the basin of each fold in the spider with enough slack on top for an unrestricted excursion.

8. NVX Embossed Rubber Magnet Boot

We didn't even skimp on the magnet boot for our N-Series subwoofer. Besides looking better than a bare magnet the rubber boot protects the magnet from chipping and possible corrosion that can affect magnets exposed to the elements.

NVX for the win..

NVX Tweeters, Midbass and now the Subs, I believe NVX is firmly committed to SQ and offers a great product for a tremendous value. This subwoofer is their 2nd Generation and has the non-pressed paper cone, i spoke with NVX why they switched from Polypropylene to Paper and he told me lot's of reasons but mainly SQ and after listening to the subs for an extended session i have to agree that they sound fantastic in a 3.2 cu ft vented enclosure with 50 oz of polyfill, i can't imagine the SQ getting much better than it is right now and close to 130 db's is plenty loud for me, my ears are still ringing..
Each sub is wired in series for a 4 ohms then both subs are paralleled for a 2 ohm final load impedance on a 500 Wrms channel, they pound the ground and shake my entire full size van, much louder than the MTX Terminators that were replaced and i had to cut the bass knob back..
I highly recommend these subwoofers, the 1st Gen subs got lots of 5 star reviews and once people catch on to the 2nd Gen they will too, am extremely happy with my purchase and have nothing but good things to say for the NVX Brand speakers and subwoofers..
NVX for the win, the VSW122V2 is probably one of the best under $70 subwoofers on the market and i wouldn't hesitate to use any of their products..

Solid choice

I put one of these in a 1.25cuft box in my accord on an mrv-m500 wired to 4ohms and tune the amp to put out 300tms with my multimeter. Gotta say; at only 300 watts this is pretty impressive. Still fairly tight for a 12" but plenty of bottom end for what I usually listen to. I'm planning another build but two of these next.

NVX NSW122v2 (Poor Quality, Buyer Beware)

I bought a pair of NVX NSW122v2 at the recommendation of the Sonic Electronix sales representative who spoke highly of NVX and claimed the the subs price and performance far exceeded the competition. Taking the sales rep advise I decided to purchase a set of NVX subs for my 2016 Chevy Silverado. Well it hasn't been two years since the day I purchased the subs, had Best Buy install them, and had to file two warranty claims with NVX for defective subs. The subs look and sound great when they work normally, but unfortunately they tend to break after a few months of usage. Luckily, I purchased the square trade warranty through Sonic Electronix, so I had to file a 3rd claim after my replacement subs started malfunctioning. I will not recommend this subs to anyone, spend a little more and buy some Kicker, Alpine, JBL, or Pioneer Subs. The old adage that says, "You get what you pay for" densely applies to this subs. Buyer Beware!

Great sound

The bass from this sub is deep and clean. The mounting depth is efficient for almost any 12 sub box. I'll recommend to anyone that want clean sounding bass.

Pros - Well built, sounds good.
Cons - None so far.

Nice subs!

Hooked up 2 of these to my 1000 W RMS amp with the gain turned down while I break them in. Sonic got them to me right on schedule, and they sound great so far. Dual voice coils are a great feature and I can see the quality built into these subs. Using a sealed box with recommended volume of 1.25 cu.ft. per chamber during break in, so far I don't think I will need to move them to a ported box after they loosen up. Great SQ at this power level, nice subs at this price point.

Good entry level subs

Easy on pocket and they hit the lows with deep rumbling bass

Really good subs for 59.99 ea

I have 2 of these in a dual ported box running off the bda7501 amp and it is the perfect combo for what I am running. I was very impressed with sound when first installed each time I listen to them I have to dial back the bass remote because the bass hits so hard I think I'm going to blow a sub. I recommend these subs and the nvx bda7501 amp to power them.

Solid gear

This sub met my needs perfectly. I needed a low cost high quality driver with reasonable efficiency. I also needed to be under 5 inches top Mount depth. It fit my truck box for the tundra crewmax behind the rear seat perfectly and gave me plenty of clean bass. Only time will tell if it can handle the abuse to come. I'm using a rockville rxa t1 to power it. It's a great match. Cea compliant to match the sub and pushes it to the limit as well.

Bit of a disapointment

Dont get me wrong if your lookin for a clear sounding sub, then this sub is perfect. However i was expecting more of a boom, most music i play i can not tell i even have a sub.! Of course though if the song has low end bass it sounds ok.

Great entry-level subs for the price!

I purchased these last November as a black friday special after a fitment issue with the pioneer champion series that came with the bundle( I know right?). The customer service rep spoke highly of her brand and I went with his recommendation for these NVX'23r hrs. I installed them into a nice 2 sub ported Belva box with 1.75 cubic ft per sub tuned at 40hz. Wired them in parallel 380 watts @ 2 ohms to my NVX JAD900.5. I broke them in out of the box with a single tone generator because I wanted to bang asap. They sounded great in the trunk of my Monte Carlo for months. I then put them into my Mazda 3 hatchback faced upward using the same amp.* I thought one of the subs blew because of it making a terrible rattle and only ran one sub 210 watts @ 4 ohms. After 3 months of only one sub, I found out that the dust cap came unglued. The cone was still nice and glued, so I bought some clear speaker adhesive and fixed my issue. Got both of them hooked back up and forgot how loud both of them were together. I really enjoyed my time with just one sub because it didn't bang as hard and fell in love with the sound quality. I play all sorts of genres from rap, EDM, dubstep, house, metal,to alternative. They can play anything I throw at them and do it accurately. A bunch of expensive name brand subs aren't even capable of going below 28hz and these go all the way to 20hz. While it may not produce those low notes loudly, their presence is there and can be heard clearly. One day I'm considering putting more power to them or a higher end NVX sub one day, but these will definitely put a smile on your face, even with only 200 watts each. Go ahead and get at least 2 of them. You know you want to!

I'm removing one star for the dust cap coming unglued. Everything is working great since I glued it back.

Box killer

Ok fair warning these subs will kill your box if it is weak. Tuned my amp at 800w rms 400/woofer at Max volume. At 60% volume about 300w each. Very clear sound very nice low resonance. In my Sierra box choices are limited so I went with the generic box with about 2 ft cubed total. After about 3 weeks or so I started to hear a rattle and thought I burnt a coil or messed up a spider. Nope....I split my box at the seams. If you get these subs, take some of the money you save and invest in a strong box. They slam hard. Not loud but very clear and very hard. Definitely looking at putting a set in my wife's car.

Great subs for the price

I bought 2 of these, put them in a 1 cubic foot per chamber sealed box with a pound of fill per chamber, wired at 2 ohms to a kicker cx600.1 and they sound great. Extremely clean and tight bass. They replaced 2 of the older alpine type s's that blew. They're not quite as loud but they sound cleaner and punchier. Also the alpine's were in a ported box, I think if I had these in a ported box they would be about the same. As for durability I've had them for about 3 weeks now I think, running just below clipping from the amp, for atleast an hour drive everyday and seem to be good and getting a little louder as they break in. I think the look and design are great. They look awesome in the box in the trunk, not too flashy but look like solid quality. Overall for the price these are a great buy. Would definitely recommend these for anyone on a budget like me looking to add some bass. And as always sonic delivered fast and packaged well with great prices, love the company, will be buying all my audio equipment from here.

NVX NSW122v2

I have been out of car audio for 20 years. All the basic principles still apply. These subs sound pretty good for the money they are a steal. I have them in a tight box poly filled with 325 rms. They hit as tight as 10s and still hit the lows fairly well. I’m guessing that the 1.25 or a little bigger would really bring them alive. I think with them in a little tighter box they could use 500 rms. No complaints the more they break in the better they sound.

Good starter.

For an entry sub, and for the price, it's pretty good. I put 2 in a custom box, tuned to the recommended he and air space for 1 sub, but the ft^3 multiplied by 2. It hits the lows good and can handle a a lot. I only have 400 watts rms to both right now but it can handle up to 700 watts rms safely! The wiring is a bit confusing, being that a dual voice coil subwpofer isn't exactly "entry level", but it's easy to learn and a guide is offered here on sonic. I'm satisfied with them so far and I would definitely recommend them to a friend and anyone looking for first time subs.
