High-Level Speaker Wire Connections - Definitive Technology SuperCube I Owner's Manual

or you wish to use the SuperCube subwoofer's low-pass crossover and control in
addition to the low-pass crossover in your decoder, simply plug the sub or LFE
output of your decoder into the left or right low-level input of your SuperCube
subwoofer. However, in almost all cases, a dedicated LFE output already has its
program material tailored for input into an unfiltered LFE input and as such
should be fed into the LFE input on your SuperCube.
Alternately, another way to hook up your Definitive Technology SuperCube
subwoofer is via the low-level input connectors which are gold-plated RCA-type
jacks designed to accept standard audio interconnect cables. For preamps and
decoders, run an interconnect from the left and right outputs of the preamp or
decoder to the left and right low-level inputs on the subwoofer. If you have two
sets of outputs, you can use one set of these; if not, you can put a Y-connector into
each output (left and right) and run half of each Y back into a (left and right) main
input on the preamp decoder, receiver or power amp and the other half into the
(left and right) low-level input on the subwoofer.

High-Level Speaker Wire Connections

Your Definitive Technology SuperCube subwoofer can also be hooked up via
high level connections. In this situation, you have the option of running your main
speakers "full range" or rolling off the low end by using the high-pass filter built
into the subwoofer. For high-level wiring, your interconnects are simply equal
distance lengths of high quality speaker cable.
To hook up your SuperCube subwoofer via the high-level connections, simply run
speaker cable from the right channel high-level connector on the subwoofer to the
right channel speaker connector of your receiver or amplifier. Repeat this process
for the left channel. Please take care that the red (+) terminal on the subwoofer is
connected to the red (+) terminal on your receiver or amplifier, and that the black
(-) terminal on your receiver or amplifier is connected to the black (-) terminal on
the subwoofer. This will ensure absolute phase throughout your system.
Your main speakers can now be connected in one of two ways. If you wish to
utilize the high-pass filter built into your subwoofer, simply connect your main
speakers to the high-level out terminals on the subwoofer. [See Diagram 2.]
Again, take care to make red to red (+) and black to black (-) terminal connec-
tions. This connection will provide a smoothly contoured roll-off of the low fre-
quencies going to your main speakers starting at 80 Hz. For more overall bass out-
put when using full-range main speakers, run the main speakers full range by
hooking them up directly to the amp. In many systems, if your speakers are true
full-range systems, you may find that you get a more satisfying sound by running
the speakers full range and crossing your subwoofer in fairly low (40 – 70 Hz).
On the other hand, if you find that you are overdriving your main speakers, you
will be able to play your system louder by using the built-in high pass crossover
for your main speakers.
The Advantages of Multiple Subwoofers
Definitive's SuperCube subwoofers are engineered to be used singly or in
5
stereo pairs. With a single subwoofer, both left and right signals are sent to the
