PSB SubSeries: The PSB SubSeries 150 powered subwoofer is designed to
provide the flattest possible frequency response, full bass extension, low
distortion, and high output. The PSB SubSeries powered subwoofer is perfect for
music and movie soundtracks.
Class D Discrete MOSFET Amp: The PSB SubSeries 150 powered subwoofer
employs a custom-designed Class D discrete MOSFET amplifier rated at 100W RMS/200W
Peak. The built-in digital
amplifier features an automatic varying switching frequency that
maintains maximum efficiency and low THD under all conditions. The Class D
amplifier also incorporates proprietary limiting circuitry preventing audible
overload while remaining true to the dynamics of your music or movie sound
track. This circuitry combines peak limiting circuits that hold amplifier
signal swing to the point just short of the amplifier's clipping, with
compression circuitry that will reduce the amplifier's gain.
6.5" Woofer: To compliment the powerful Class D amplifier, the
SubSeries 150 uses a front-firing 6.5" polypropylene cone woofer with rubber surround,
high-temperature voice coil and vented pole piece. The woofer is designed to reduce mechanical
noise and prevent harsh sounds at extreme excursion.
Top-Mounted Controls: Three rotary control knobs
(volume/crossover/phase) are provided on the top-panel of the powered sub for
- Volume Control: The rotary volume knob controls the output level of
the powered subwoofer, relative to the volume of the other speakers in the
- Low-Pass Crossover: The low-pass crossover adjusts the
high-frequency roll-off of signals sent to the subwoofer. The control is
continuously variable from 50 Hz to 150 Hz, and allows you to precisely
match the subwoofer's bass production with your system's main left & right
- Phase Dial: The phase dial allows for the
adjustment of the phase of the subwoofer in relation to the speakers used in the
system; from 0 to 180 degrees.
Inputs & Outputs: The PSB SubSeries 150 powered subwoofer offers LFE
and stereo RCA inputs, as well as LFE and stereo RCA outputs.
- LFE/Stereo Inputs: A LFE or stereo RCA input is provided for
connecting your receiver. You can use a single RCA cable
to connect the LFE (low frequency effects) Output of your
receiver, preamplifier, or integrated amp. Since the LFE output is filtered on
the receiver/preamp/amp, the subwoofer's variable low-pass filter is bypassed. If your receiver or integrated
amplifier has preamp outputs, or if you are using a preamplifier without a
designated LFE output, the preferred connection is to use a stereo RCA cable
plugged into both left and right inputs. In this case, you will use the
powered sub's low-pass crossover.
- LFE/Stereo Outputs: A LFE or stereo RCA output is provided for
daisy-chaining another powered sub. The LFE output is filtered by the
powered sub's built-in low-pass crossover, while the stereo RCA outputs are
unfiltered and full-range.
Flexible Mounting Options: The SubSeries 150 powered sub can stand up
vertically or horizontally for placement behind or beside a sofa or chair. You
can also lay the powered sub down and slide it out-of-sight under a couch or end
table. You can even wall-mount the SubSeries 150 using the included
wall-mount bracket. Dimensions are as follows based on mounting application.
- Vertical (w/ feet): 17.5625" (w) x 11.0" (h) x 5.625" (d)
- Horizontal (flat on back): 17.5625" (w) x 4.8125" (h) x 10.6875"
- Wall-Mount (w/ bracket): 17.5625" (w) x 10.3125" (h) x 4.8125"
Auto On/Off: The powered subwoofer features a main power
switch on the back panel. When switched to On, the subwoofer is initially in
stand-by mode, awaiting the presence of an audio signal. When the signal is
received, the subwoofer turns on automatically. When no signal is detected, the
sub's amp will automatically turn off after approximately 15 minutes. In the Off
position, the subwoofer will not power up. A green LED, located on the front
panel between the control knobs, will glow when the subwoofer is active (it will
glow red when off).
