SuperCube I &
SuperCube II
The following will detail the amplifier removal process for Definitive
Technology subwoofer models SuperCube I & SuperCube II. Some models
may be Labeled Powerfield SuperCube.
The subwoofer should be unplugged from any receiver or power amp that it may be plugged into.
Disconnect the speaker from AC power at least 60 minutes prior to starting. Gather the tools you will
need in a clean well-lighted place:
• a Phillips head screwdriver
• a flat head screwdriver (optional)
• 4 small plastic cups, with labels
• a (small or tack) hammer
• a needle nosed pliers (recommended)
• a digital camera (or pen and paper)
• 3mm hex key (high-level amp)
• 4mm hex key (woofer)
Remove End Caps and Logo
1. Remove both end caps.
a. The top end cap lifts off using as purely vertical a motion as possible.
b. The bottom end cap is secured onto the cabinet by long wood screws.
i. Remove them and set aside the bottom end cap.
ii. Mind the gloss finish.
iii. Reserve the screws in the 1
st
container, labeled “end cap”.
2. Remove the logo
a. The logo is held in by simple tension
b. The pegs that press into the cabinet are located beneath the left and right sides of the
logo.
c. Using a flat bladed screwdriver slightly pry up one side. Then slightly pry up the other
side.
d. This should expose enough space between the middle of the logo and cabinet to insert
your screwdriver between the pegs and pop the logo right off.
Remove the Low-Level Amplifier
1. Lay the speaker down gently on its belly, so that the amplifier to be removed (entire back
panel) is facing toward the ceiling.
2. Remove the screws that are along the outer edge of the back panel.
CAUTION: Only remove the screws along the outer edge of the back panel.
As you get the screws out drop them into a 2
nd
plastic cup labeled “LL/Temp”.
a. It is very important that you retain all the original screws.
