Feet
Your HTPS-400 subwoofer is
equipped with 2 sets of feet
for use depending on the type
of surface the subwoofer will
be placed on. Enclosed with
this manual is a set of rubber
self-adhesive feet for use on
hard surfaces, such as wood
or tile floors, and a set of
spiked feet for use on
carpeted surfaces. To install
the feet, set the subwoofer
gently on a padded surface
with the bottom side up. If 
you are using the rubber 
feet, attach them to the four
corners of the unit, covering
the holes. If you are using the
spiked feet, install them by
pressing them into the holes.
The subwoofer may not
perform as well as expected if
you neglect to attach the feet. 
Grille
Your HTPS-400 subwoofer has
been packaged with the grille
unattached for shipping pur-
poses. In some applications,
such as custom installations,
the grille may not be necessary.
In cases where a grille is
needed, carefully align the
grille pegs with the grommets
and insert the grille. The grille
is not designed for frequent
removal, and cannot be
readily removed with bare
hands. If for some reason it
becomes necessary to remove
the grille, it should be pried off
very carefully with a small, flat-
tipped, jewelers’ screwdriver,
taking extra care not to
damage the baffle or the grille.

Experiment with placement for
the most accurate and uniform
bass response throughout the
room. It is important to avoid
blocking the grille of the
subwoofer.
Since the HTPS-400 is video-
shielded, it may be placed in
proximity to a television
monitor.
A single HTPS-400 subwoofer
meets THX Select requirements
for a 3000 cubic-foot room.
However, to meet THX Ultra
requirements for a 3000 
cubic-foot room, two or more
HTPS-400 subwoofers are
required. The preamp output
featured on the HTPS-400
simplifies the hookup of
multiple units (see page 4).

The HTPS-400 contains a 
signal-sensing auto turn-on/
turn-off circuit. This feature
will automatically turn the
subwoofer on when you turn
your system on with the power
switch in the “Auto” position
and begin playing any program
material. The subwoofer will
return to standby mode when
no signal is received for
approximately 15 minutes. The
power switch’s “Off” position
is for vacation use only.
The Crossover Frequency
adjustment determines 
the highest frequency the 
HTPS-400 will reproduce. It
allows a seamless transition
from the subwoofer to the
satellite speakers. Experiment
with this adjustment to 
find the crossover frequency
that sounds best with your
speakers.
Note
: When the THX/Normal
switch is set to “THX,” the
internal crossover is bypassed.
Crossover frequency is then
adjusted at the THX processor.
The Phase switch is used to
adjust the relative polarity of
the subwoofer to the other
speakers. When the speakers
are out of phase, the low-
frequency sound waves will
cancel each other out,
reducing bass response. 
The HTPS-400 provides a
convenient phase switch that
allows you to remedy this
situation without relocating
the speakers or changing any
speaker connections. In
normal THX operation, the
Phase switch should be set to
0 degrees so that the sub-
woofer is operating in phase
with the main speakers. This
should produce a smooth
frequency response up to
80Hz. In rare cases when the
subwoofer is placed more
than 25 feet away from the
main speakers, or where the
subwoofer is not being used
with a THX-certified receiver,
or processor, and speakers,
the 180-degree position may
provide a smoother frequency
response.
Listen to your HTPS-400
subwoofer and main speakers
with the switch in the “0°”
position, then listen to the
same material with the switch
set to “180°”.  Decide which
sounds better and leave the
switch in this position. Repeat
this procedure if you change
the location of the subwoofer.

make sure that you have
configured your processor/
receiver so that the subwoofer/
LFE output is on.
If there is no (or low) bass
output:
• Make sure that the sub-
woofer is plugged into a live
electrical outlet and the
power switch is in either the
“Auto” or “On” position.
• Adjust the “Crossover
Frequency.”
• Adjust the “Output Level”
(Gain) control.
• Change the setting on the
Phase switch.
• If you are not using a THX-
certified processor/receiver,
make sure that you have
configured your processor/
receiver so that the sub-
woofer/LFE output is on.
If you are hearing midrange
frequencies (such as vocals)
through the subwoofer:
• When using the THX mode,
make sure the subwoofer
crossover is activated on your
processor/receiver.
• When using the Normal
Mode, adjust the “Crossover
Frequency” to a lower 
frequency.
