Krell Industries MASTER REFERENCE SUBWOOFER Owner's Reference Manual page 23

Placement
Before you install the Master Reference Subwoofer, review the following guidelines to
choose the location for the subwoofer. This facilitates a clean, trouble-free installation.
Make sure the Master Reference Subwoofer, in addition to other items (amplifiers,
other system components, furniture) in the listening room, does not exceed the
listening room's maximum floor load.
Each Master Reference Subwoofer requires at least two inches (5 cm) of clearance
on each side and in front, and at least two inches (5 cm) of clearance above and
to the rear of the subwoofer for adequate ventilation.
IMPORTANT
For optimum sound quality, place your subwoofer at least one foot away from any wall.
Your Master Reference Subwoofer can operate from a number of positions in
your listening room. The range of control provided by the programmable electronic
crossover, plus the subwoofer size and construction, help ensure excellent perfor-
mance from nearly any location. Figure 1, on page 16, illustrates three possible
placement options, which are described below.
Option 1: Stereo. Place the Master Reference Subwoofer midway between the left
and right loudspeakers.
Option 2: Home Theater, Rear Projection. Place the Master Reference Subwoofer
between the center and left front or between the center and right front loudspeakers,
preferably one foot from any wall.
Option 3: Home Theater, Front Projection. Place the Master Reference Subwoofer
midway between the left and right front loudspeakers and between the center speaker
and the screen.
If you employ Krell CAST technology, you can use CAST interconnect cables of any
length. Try to keep cable length to a minimum if you select single-ended operation.
AC Power Guidelines
The Master Reference Subwoofer should be operated from a dedicated AC power
line rated at a minimum of 20 amps.
Please contact your authorized Krell dealer, distributor, or Krell before using any
devices to alter or stabilize the AC power for the Master Reference Subwoofer.
