Compatibility: This enclosure is designed to accommodate two 12" woofers.
It is a Type 2 enclosure with a total internal volume of 2.5 cu. ft., and can be
configured as a sealed or ported enclosure.
box is constructed of 5/8" MDF (medium-density fiberboard), with a second
1" MDF panel attached to the front panel to provide the mounting baffle
for the woofer. MDF resists flexing and has
The enclosure consists of two 1.25 cu/ft chambers. 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 with tough ABS edge trim.
Baffles: The front baffles can be removed and replaced with optional baffles
for woofers with non-round cutouts. Eight Allen-head screws can be removed,
enabling you to remove each baffle. A 4mm Allen wrench is required to
loosen/tighten the screws.
The QXs-Ring is a multi-diameter woofer mounting adapter which also seals the
woofer into the enclosure. Each QXs-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 QXs-Ring can be trimmed off, allowing for an extra
1/8" in woofer mounting diameter.
Pre-Cut Slot Port Hole:
The box comes configured as a dual-compartment ported enclosure with a tuning
frequency of 34Hz, with a pre-cut, 2-3/4" x 11-1/2" slot port with a hard
plastic port flange between the woofer cutouts. If the driver manufacturer
suggests using a sealed enclosure, or that a sealed enclosure is preferred, you
can replace the port flange with the supplied slot port plug, using the same 4
screws from the port flange. Note: There are no provisions for port
trimming with the slot port.
This enclosure has two sets of spring posts speaker terminals located on the
back of the
enclosure. The spring posts will accept bare wire,
pin connectors, banana plugs, and dual banana plugs.
