NVX NSW122v3 12" 700 Watt Car Subwoofer + MDF Sealed Enclosure

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..

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.

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.

Good entry level subs

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

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.

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.

Entry level... my foot!!

These babies Boom! Amazed by this entry level sub from NVX! Great SQ and loud! I have been through a lot of subs. These rate in the top 10 with me! Thanks Sonic!!!

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.

Nice box

This is a really nice box. I have a Boston Acoustics G5 in it and it pounds!!! I wanted to save space in trunk by switching to small sealed box instead of the big ported I was using previously. I thought I would be taking a hit in SPL but surprisingly I didn't. Just a gain in SQ. And I gained about 50% more trunk space.
