Our take on the NVX Single 15" Ported 3/4" MDF Subwoofer Box with Polyfill

The NVX NE151P is an empty single 15-inch ported enclosure built from 3/4-inch MDF with reinforced joints to resist flex under high output. A slot port is tuned for deep, efficient low bass, and the box comes with polyfill and spring terminal posts. It suits drivers who already own a 15-inch sub and want a sturdy prefab box for a trunk or cargo area. Against generic prefab boxes, the thicker MDF and braced joints are the main step up; it is a universal box, so it is not built to one sub's exact specs.

About the NVX Single 15" Ported 3/4" MDF Subwoofer Box with Polyfill

The NVX NE Series NE151P is a universal empty subwoofer enclosure that holds a single 15" subwoofer. It is a ported (vented) design with a precision-tuned slot port, which is intended to increase bass output and efficiency and give a deep low-end response.

The cabinet is built from 3/4" Medium Density Fiberboard (MDF) with reinforced joints to reduce box flex and withstand high acoustic pressure. It is finished in durable, high-density black carpet and fits in the trunk of a car, SUV or truck. High-efficiency terminal posts provide the power connection. Polyfill is included in the product name.

Questions and answers

Is this box loaded with a subwoofer?
No. It is an empty enclosure; you supply and install your own single 15-inch subwoofer.
What is the box made of?
3/4-inch MDF with reinforced joints, finished in black carpet, with a slot port and spring terminal posts.
Does it come with polyfill?
Yes. Polyfill is included, which helps smooth the internal response of a ported box.
Will it fit my 15-inch subwoofer?
It is a universal single 15-inch enclosure, so it fits most 15-inch drivers, but check your sub's mounting depth and cutout against the box's opening before buying.
Is ported better than sealed for my setup?
Ported boxes like this one play louder and deeper around the tuning frequency; sealed boxes are smaller and tighter. Choose ported if you want maximum output.
Can I use it in an SUV or truck?
Yes. The carpeted cabinet suits a trunk, SUV cargo area or truck cab, as long as you have room for its footprint.
