Frequently Asked Questions (FAQ)


Both S-series and SQ-series subwoofers are categorized as shallow-mount subwoofers. However, SQ Series is designed for higher power and more precise bass, while the S Series is a more budget-friendly entry-level shallow option.
Shallow doesn’t have to mean weak. SMW104 uses a non-pressed paper cone and high roll surround to maintain a low resonant frequency. It hits the gut-punch notes that other shallow subs usually miss entirely.
Not at all. Despite its relatively thin build, you need to have an external monoblock amp to move the 300W RMS motor. Stock power would destroy the subwoofer.
Tight boxes are heat traps. NVX added a vented pole piece to help the 2" coil breathe. Just ensure the back of the magnet has at least an inch of clearance so the vent can actually exhale hot air. Don't choke your bass!
If you have 8 inches of depth, go with NSW82/NSW84. If you have 4 inches, SMW104 is your savior. This subwoofer is designed to fit in tight spaces without the weak performance of generic budget shallow subs.

Excellent shallow mount subwoofer for the money! Well done NVX!

I purchased two of these and have only tried one so far. I have the 10" version in a nicely built prefab box (currently for test purposes) that specs right about 0.81 cuft sealed. I'm currently testing it in a preexisting system in a Honda S2000. Its being powered with a 500 watt NVX VAD series amplifier. I have to say that this subwoofer has impressed me more than I expected. The sound quality is quite good for this dollar amount. I am very happy to see that NVX chose to use a rubber surround as opposed to the foam on many of their other subs. I cannot speak to longevity or durability as I haven't had them long enough to comment on that. I'm planning to install them in the spare tire location in my 2022 Veloster N. At just 3.23" deep there will be plenty of space. I hope NVX continues along this line of design for their future of subwoofers. Thank you NVX! Well done!

Amazing shallow mount

So I’ve been building more of sq system, not a super high end one but a great one nonetheless. So I have a nice 3 way front stage and a set of coax NVX x6.5” in the rear doors. I loved how well those are doing so as I was looking at shallow subs (very new to me) I didn’t want to spend a ton. Being as though I’ve never had a shallow sub I figured I would start by building a 1.1 cf. box tuned to 34hz and then looked for subs under the $200 point. I found one of these as opened box for like $60! First off I had a 10” full sized sub before this now it wasn’t something that was 1500-2000 watt spl subs it was a P3 in a 1.25cf at 30hz with around 500-600 watts. It sounded great just couldn’t manage the box size in my car the way I wanted. My box now is only 5” deep so I’m able to hide it under my false floor. This NVX is putting out some amazing lows and very clean at that. Everyone who has gotten in A) doesn’t think it’s a 10” and B) nobody believes it’s shallow at that. It really sounds like a mid range full sized sub and I can’t explain how happy I am with this sub! If you’re in need of something shallow whether it’s a 10 or 12 don’t feel like you need to spend $400-$500 on a JL or other overpriced product. These will 1000000% not disappoint!
