Frequently Asked Questions (FAQ)


NE122S is better for audiophiles who want a tight but not forceful bass. Like other sealed enclosures, NE122S is quite smaller so it would save some space in your car. However, if you really want an earth-shattering low-end, go ahead with NE122P instead.
Most likely not. For example, the NE122S has a generous mounting depth of up to 10-1/8". That’s enough clearance for even the beefiest competition-grade magnets to breathe without slamming against the rear wall.
A dual enclosure ensures both subs share the same physical footprint, preventing them from sliding around independently. It makes installation and wire routing significantly easier than manually have two boxes.
We don't recommend. NVX includes just enough to help the box act about 15-20% larger sound-wise. Adding too much can actually choke the sub's movement. Only add more if your sub's specs significantly exceed the box's actual internal volume.
It’s for durability and fitment. Sharp MDF corners under carpet are prone to bruising or chipping during installation. Rounded edges prevent the carpet from tearing and make it much easier to slide the box into tight trunk gaps.

Very high quality

The following review is for a previous version (12DS).

I purchased this box for a pair of Kicker Solo Classics. The box itself is very well constructed, solid and well sealed. I did further seal it with silicone for peace of mind, including the terminal cups. I used 1/2 lb per chamber of polyfill and mounted the subs. After initial break-in, I can attest that the SQ of this setup is definitely top-tier, one of the best I've ever heard, which is what I was seeking. I have no doubts this box will outlast every other component of my system.

OOPS

The following review is for a previous version (12DS).

This was advertised to fit the Rockford Fosgate P2D2-12 pair I bought. The speakers did not fit in the box together. Good product but did not work out as I wanted.

Great for the value

The following review is for a previous version (12DS).

When it comes to premade box's Atrend is hand's down one of the best in the market. Also with Sonic's price you can go wrong.

Nice box, but?

This box sounds awesome with my NVX subwoofers. I had to reflue the poly inside the box because not enough glue from production. Also, the terminals are cheap. Replacement is recommended. All that aside this box hits hard with the optimal manufacturers recommended air space. I replaced some CT Sounds 1250 rms Stratos off a 2000.1D CT amps. They couldn't even keep up, even with thier amps.alway bottomed out. I put the NVX3s in A NVX box with the specs. Night and DAY. These subwoofers just my be better than the JL W7. By the way the CT Sounds are in a custom box .

Great enclosure for the money!

The following review is for a previous version (12DS).

This box is seriously best bang for your buck! I have 2 brand new Illusion Audio 12's and this enclosure fit the specs perfectly!
Well built and no leaks that I could find. Which was a concern to me because the black sealant used didn't have total coverage in both chambers. Easy fix regardless, but wasn't needed luckily.

Love how the rear has an angle to scoot right up to your rear seats. This is great if you have an SUV or hatchback. And the design is nice and compact. I could still fit 3 large cases of water in the back of my 4runner with this box back there.
