Our take on the NE81P Single 8" Slot Ported 3/4" MDF Black Carpeted Subwoofer Enclosure – 0.75 Cu. Ft. with Polyfil and NVX Logo

The NVX NE81P is a single 8-inch slot-ported subwoofer box built from 3/4-inch MDF and pre-lined with Poly-Fil. It offers 0.75 cubic feet of internal volume, a 38 Hz tuning frequency, and a 1 x 10-inch slot port 21 inches long. It suits someone who wants a compact, pre-built ported box for an 8-inch sub without cutting wood. Against generic prefab boxes, the CNC-cut MDF, spring-loaded terminals and factory Poly-Fil lining are the main draws. It is not compatible with NVX VC-Series or XC-Series subs, so check your driver first.

Pros
  • 3/4-inch MDF construction with CNC-cut panels
  • Pre-lined with Poly-Fil for better acoustic response
  • Slot port tuned to 38 Hz for deeper output than a sealed box

  • Compact footprint at roughly 15 x 15 x 11.5 inches
Cons
  • Not compatible with NVX VC-Series and XC-Series subwoofers
  • 8-5/8-inch mounting depth limits which 8-inch subs fit

Questions and answers

What subwoofers fit this enclosure?
Any 8-inch sub with a 7-3/8-inch cutout diameter and no more than 8-5/8 inches of mounting depth. NVX VC-Series and XC-Series subs are explicitly not compatible.
Is this box ported or sealed?
It is slot-ported, with a 1 x 10-inch port 21 inches long tuned to 38 Hz. That gives more low-end output than a sealed box of the same size.
What is the internal volume?
0.75 cubic feet before subwoofer displacement. Match it to a driver that calls for a ported box in that range.
Does it come with Poly-Fil installed?
Yes, the box is pre-lined with Poly-Fil, which helps damp internal standing waves and smooth the response.
How do I wire the sub to the box?
The box has spring-loaded push terminals. Run speaker wire from your amp to the terminals, then from the terminals to the sub's voice coils.
What are the outer dimensions?
15.25 inches deep, 15 inches wide and 11.5 inches tall. Measure your cargo area before buying.
