Subwoofer Installation
Your new SuperCube subwoofer contains a built-in amplifier and sophisticated
electronic crossover. There are several ways to install your subwoofer. One setup
is not considered “better” than another; rather, each is a function of what type of
entertainment system you own and how you plan to integrate your components.
Read the installation suggestions below to determine which options best suit
your needs. Please take care to perform all wiring procedures with your system
completely powered down.
Unpacking
Each loudspeaker leaves our plant in perfect condition. Any visible or concealed
damage most likely occurred in handling after it left our plant and should be
reported at once to your Definitive dealer or the delivery company that delivered
your loudspeaker. Please unpack your system carefully. Save all cartons and packing material in case you move or need to ship your system. Record the serial number found on the back of the subwoofer in the appropriate place on your warranty
card. Mail in your Warranty Card within 10 days of purchase.
Subwoofer Placement
Your Definitive Technology subwoofer has been designed to operate at frequencies
generally below 150 Hz. Because low-frequency information in this range essentially is non-directional, your subwoofer can be located anywhere in your listening
room that is most convenient. Also, the continuously variable low pass filter operates at a very fast roll-off, ensuring great performance wherever you place your
subwoofer. There are, however, some general rules that you should bear in mind
when locating your subwoofer:
1.
For maximum output, the subwoofer should be placed in a corner or against
the wall, leaving roughly 2- to 4-inch clearance between the subwoofer and
the wall(s).
2.
Corner placement will increase the subwoofer’s efficiency, which in turn
will increase your system’s maximum output and improve the dynamic
capability of the subwoofer.
3.
While one Definitive Technology subwoofer will always sound great, the
use of two subwoofers will definitely enhance your system’s performance
by providing a smoother and more consistent response pattern. Here, it is
recommended that you locate the subwoofers on the same side of the room
as the main speaker of the same channel.
4.
Always remember that frequency response and output level are greatly
influenced by the subwoofer’s placement. A movement of even a foot or
two can dramatically change your system’s response characteristics. You
should experiment with placement in your particular listening room in
order to achieve the highest performance from your subwoofer.

Placement Inside a Cabinet or Cavity
The SuperCubes, because of their unique low-frequency radiation properties, can be
placed inside a cabinet or cavity with excellent results. Just be sure to leave at least
2 inches of clearance on the sides and front of the subwoofer, and with the Trinity
Signature, 2 inches on the top, sides and rear if the subwoofer is placed on its back.
Wiring Diagrams
Low-Level Connections
Most often used is the LFE connection. Most receivers, preamps and decoders
feature a mono (line level) LFE/subwoofer output intended to be used with subwoofers. You can feed the mono or LFE subwoofer output of your receiver or
decoder to the LFE input on the subwoofer and achieve full performance.
Diagram 1.]
Usually, these outputs have their own low-pass filter built into the
circuit, and if this is the case, you would normally input them into the LFE input.
The LFE inputs on your SuperCube subwoofer are direct coupled inputs which are
not affected by the subwoofer’s low-pass filter or low-pass crossover control. If the
sub or LFE output on your receiver or decoder does not have a low-pass crossover
