10th Anniversary Edition - W7 8-inch Subwoofer Driver (500 W, 3 Ω)
This subwoofer driver has been called the best damn 8-inch subwoofer ever made for its remarkable performance capabilities and design attributes. An impressive linear excursion envelope that exceeds 0.75 in. (19 mm) one-way allows it to deliver impact well beyond the range of other 8-inch subwoofer drivers.
The 8W7AE is best used with amplifier power in the 200W - 500W range and is optimized to operate in a 0.875 cu. ft. (24.8 l) sealed enclosure, or a 1.0 cu. ft. (28.3 l) ported enclosure. Detailed enclosure recommendations can be found in the Specifications tab.

* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** Efficiency (1 W / 1 m) is not an accurate indicator of a subwoofer′s output capability and should not be used as a comparison to other subwoofers to determine which one is “louder”.
