NVX XMDFS102 Dual 10" Sealed 3/4" (2.0 Cubic ft) MDF Black Carpeted Subwoofer Enclosure (Made in The USA)

The NVX XMDFS102 has a sealed subwoofer enclosure design.

This means that the air is contained and does not enter or exit the box.

This creates a tighter, more accurate sound than a ported or vented enclosure.

Because a sealed enclosure is competing less with air, the subwoofer enclosure tends to have a better transient response which allows the system to respond more quickly to sudden changes.

A sealed enclosure also offers improved acoustic suspension and cone control, which reduces distortion and improves accuracy.
