Sealed Enclosure
This subwoofer will operate well in a sealed enclosure that will yield solid, tight bass. You can either purchase a pre-fabricated enclosure or build one to suit your installation needs. Sealed enclosures are relatively easy to build and are the smallest enclosure the subwoofer is designed for.

Single Voice Coil
A subwoofer with a single voice coil can be powered by an appropriately matched amplifier or can be combined with multiple single voice coil subwoofers to achieve a variety of impedances to match your amp set up. Single voice coil subwoofers are generally ideal for low to medium-power applications.
