Ported Enclosure
This subwoofer will thrive in well in a ported enclosure. A ported enclosure is easy to spot because of the vent (port). This enclosure will be bigger than a sealed enclosure and it also has greater SPL output, resulting in chest-thumping bass with authority. For proper tuning and optimum subwoofer performance in a ported enclosure, we recommend using an amplifier with a subsonic filter.

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.
