box is constructed of 5/8" MDF (medium-density fiberboard), with a second
MDF panel adhered to the back of the front panel to provide the mounting surface
for the woofer. MDF resists flexing and has
The enclosure consists of two 0.85 cu/ft chambers. Each chamber will accept a 12"
woofer. For strength, Q-Logic uses a full dado groove on the front, back, top,
and bottom panels. The side panels are glued, then locked into these grooves.
The edges of the front, back, top and bottom use mitered joints, so there's 50%
more surface area for the special glue that bonds them. The side
panels of the box are recessed 0.5". The trapezoidal shape of the enclosure
better utilizes trunk space by allowing you to put the enclosure against the
angled back of the back seat. The enclosure is covered with durable gray carpet.
The QxE-Ring is a multi-diameter woofer mounting adapter which also seals the
woofer into the enclosure. The QxE-Ring has a series of rings around the outside
to help center the woofer, and hash marks to help align the woofer's mounting
holes. If the mounting diameter of the woofer is 11-1/8" or less, the
woofer can be installed without trimming. For woofers with a larger mounting
diameter, a portion of the QxE-Ring can be trimmed off, allowing for an extra 3/16"
in woofer mounting diameter.
Grille: The one-piece
plastic grilles fit into the outer edges of the enclosure openings and are held
in place with two self-tapping screws. The grilles offer nearly an inch of
"headroom" to accommodate woofers with large roll surrounds. Note: The
grille adds approximately 7/8" to the overall depth of the enclosure when
enclosure has two sets of spring posts located on the rear of the enclosure. The
spring posts will accept bare wire, pin connectors, banana plugs, and dual
