Owner's Manual
Congratulations
Congratulations on your purchase of a Defi
Subwoofer. This revolutionary subwoofer utilizes state-of-the-art components,
a non-resonant monocoque cabinet and low diffraction construction in order to
achieve the most lifelike sound possible in your listening room for many years
to come. The ProSub is a compact, high quality powered speaker system
intended primarily for use as a subwoofer in superior quality music or home
theater systems.
This ProSub 60 powered subwoofer incorporates a high current power
amplifier, electronic crossover and precise equalization in order to achieve the
highest possible level of low frequency performance. The amplifi
tronic crossover are completely self-contained modules which are housed in
the subwoofer. The ProSub 60 incorporates Definitive’s proprietary
PowerField®technology, by which the amplifier is specifically engineered in
conjunction with the driver for optimum load matching and power transfer
characteristics. The integrated electronic crossover incorporates high level
inputs and outputs as well as low level inputs, precise equalization, continuously
variable low pass filter (between 40 and 150 Hz), fixed speaker level high pass
filter (to match the ProMonitors) and a precision volume control. The
tremendous built-in flexibility allows easy, seamless integration with all main
speaker systems and optimum performance in any room. The crossover incorporates circuitry which allows for exceptional performance as either a single
subwoofer (blending left and right bass channels) or when two subwoofers are
used, one each for the left and right channels.
Our engineers have spent many years in developing this product. To ensure
that you only experience the fi
we encourage you to take a moment with this owner
yourself with the proper installation and setup procedures for your subwoofer.

Subwoofer Installation
Your new ProSub 60 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.
Inputs/Outputs
Your Definitive Technology ProSub 60 subwoofer operates from either
high level (speaker-type) or low level (RCA-type) outputs on your electronics. Use the low level jacks when connecting the subwoofer to the
left and right low level or LFE output jacks of a receiver, a preamp or a
signal processor. Use the high level speaker terminal inputs to connect
the subwoofer to the amplifier output (speaker) jacks of your receiver or
amplifier. Use the high level output jacks to connect the subwoofer to a
pair of left and right main speakers. (See wiring diagrams.)
When connecting the subwoofer to your system, it is recommended
that you use high quality speaker cable and try to maintain cable runs of
the same length for the left and right channels. Should you perchance
experience any level of ground hum or noise, try plugging the subwoofer
into the same circuit as your amplifier. Also, consult the
“Troubleshooting” section of this manual. To prevent accidental damage
to your subwoofer from overdriving the system, the subwoofer features
an internal overload protection circuit.

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"-4" 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’
mance 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.
s perfor-
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.
5. Your subwoofer contains a powerful amplifier inside its cabinetry.
When placing the subwoofer into a built-in cabinet, please be sure it
receives a clear flow of cooling air. If your subwoofer is to be located in
a closed-back cabinet, be sure to put some ventilation holes in the cabinet back behind the subwoofer’s back panel.
6. Since the subwoofer has some output from the rear, if you put the
subwoofer in a cabinet, leave 2"-4" around the outside of the subwoofer
for the sound from the rear to get out.
7. When using the ProSub 60 with Definitive ProMonitors, consult
the ProMonitor instruction manual for other placement tips.
