Features

Materials: The 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 anti-resonant qualities.

Design: The enclosure consists of two 1.25 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.

QxE-Ring: 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 1/8" in woofer mounting diameter.

Pre-cut Port Hole: The box comes as a dual-compartment sealed enclosure, but includes pre-cut port holes on the top panel over each compartment, each covered by a black plastic port plug and a silver elliptical plastic port flange. The flange is held in place by three Philips head screws. The instruction sheet provides a port tuning chart and guidelines on the proper length to cut the ports (two 4" diameter x 12" ports are supplied). Porting the box requires removing the port flanges and plugs, trimming the ports to the proper length, slipping the port tubes onto the fluted port flanges, inserting the port tubes from the outside of the enclosure, and the port flanges secured into place. The port plugs should be saved in case you want to change back to a sealed enclosure.

Plastic 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 mounted.

Spring Posts: This 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 banana plugs.

Brackets: Brackets (not included) are recommended for more secure mounting.
