Convertible Cabinet (specific versions

only)

The cabinet back features a removable center-section to allow for more tonal

versatility. When the center-section is left in place, the cabinet will function as a

closed-back speaker enclosure. In this mode, the sound will be more focused or

directional and the bass response will be tighter. When the center section is removed,

the cabinet will function as a semi-open enclosure. The overall volume will be

increased, especially the bass response. In addition, the sound will become less

focused and the bass will sound looser.

As speakers are "broken in" they tend to become looser sounding. This condition will

continue to progress as the speaker is used more and more. Another advantage of

being able to close the back of the cabinet is that it may help to tighten the response

of an aging speaker.

To remove the center section, remove the 10 screws along the top and bottom the

removable portion, being very careful not to press too hard on the screw heads. The

screws are threaded into T-nuts which may push out if too much pressure is applied to

the screws when removing them. If this happens, you may need to hook a pair of

needle nose pliers under the head of the screw and pull outwards on the screw while

turning it to keep the nut from turning. The center panel is designed with gaps at the

ends that are big enough to insert a coin to aid in removing the panel. Also, the panel

is raised slightly so that it can be more easily removed by hand.

When re-installing the center panel, please follow the same precautions regarding

excessive pressure on the screws.

If the back panel is to be removed to replace the speaker, the best option is to remove

just the middle and upper or lower section. This will give you access to the speaker

and should create a big enough opening to allow the speaker to be removed. If the

entire rear panel is removed in one piece, it may be damaged.
