Atrend 12SME B Box Series Single Sealed Shallow Mount Review

Made from ¾” MDF:

This shallow mount subwoofer enclosure is made from ¾ inch medium density fibreboard. This is the same material that is being used in other more expensive enclosures.

MDF is highly recommended as a speaker enclosure material because it can damp out unwanted energy and vibration. With the MDF construction of this enclosure, all you can get from your sub is great sound.

Shallow mount design:

With its shallow mount design, this enclosure should fit easily under the seats of compact cars. It can also be placed at the back of the seats of cars, trucks, and mini SUVs.

Because of its design, installation of this enclosure is also easy especially for handymen. It can also be easily removed and transported out of the vehicle.

Carpeted finish:

The black carpet of this shallow mount subwoofer enclosure not only gives it a premium look. It also protects the sub by preventing the unit from sliding around.

The carpet is firmly glued, with most reviewers saying they are satisfied with the way it was attached to the box.

Slot Vent with Black & Red Spring Loaded Terminal Cups:

The terminal is found at the back instead of being at the sides. The terminal isn’t of the best quality but most reviewers found it to be serviceable.

Fits most top-rated subwoofers:

This enclosure should be able to house some top rated subwoofers like the Pioneer TS-SW3001S4, MTX TT6512-01, Alpine SWR-T12, Boss Audio NX10FD, and RE Audio SL-12. You can also put the Pyle 12” inch subwoofers and Soundstream Stealth-13 on this enclosure.

  • It is reasonably priced
  • Fit well in most car cabins
  • It doesn’t take up a lot of space

  • It is sturdy


  • The carpet has some scent to it although it would go away after some time
  • The terminal is located at the back and not at the side
  • It’s a bit heavy at 16 pounds


  • Q. What is the mounting depth of the enclosure?
  • A.  Its top depth measures 5.25 inches and its bottom depth is 8.5 inches.
  • Q. Does it come with wires?
  • A. No, you have to supply these.
  • Q. Would it fit under the car seats of SUVs?
  • A. It would depend on the type of SUV you have. But it is designed more for mounting at the back of the seats.


This shallow subwoofer enclosure could be what you need to improve the sound quality of your car audio system. Pairing it with the right subwoofer can enhance the bass level and make you feel every low beat coming from the speakers.

This enclosure is of a shallow mount design hence you don’t need to have a lot of space in your car or SUV to install it. Plus, it is affordable and made of high quality MDF. It’s a subwoofer enclosure I can highly recommend.
