11" Woofer/300W Amp: The Focal Chorus series SUB300P powered sub employs a 11"
Polyglass woofer powered by built-in 300W RMS/450W Peak BASH amplifier for
dynamic bass response from movie and music soundtracks.
Aerodynamic Port: The Focal powered subwoofer utilizes a down firing
aerodynamic port greater efficiency and bigger bass.
MDF Enclosure: The Focal Chorus series powered subwoofer features an
ultra-stiff MDF cabinet (up to 1" thick) with non-parallel sides to prevent
unwanted distortion caused by vibration and standing waves.
Controls: The Focal Chorus series powered subwoofer features
individual controls to tailor volume, crossover frequency, and phase adjustment.
- Volume Control: The powered sub has a rear-panel rotary
volume control to adjust the volume of the subwoofer relative to the other
speakers in the system.
- Crossover Frequency: The powered subwoofer offers a
continuously variable low-pass filter, adjustable from 40-160 Hz.
- Phase Adjustment: The subwoofer's phase adjustment
allows you to adjust the subwoofer's phase between 0°
or 180°. If the bass sounds muddy or
unclear, adjusting the phase control can sometimes strengthen the bass
Connections: The Focal powered subwoofer offers LFE/RCA inputs, plus
speaker-level inputs and outputs.
- LFE/RCA Inputs: The powered sub has gold plated left & right RCA
line-level inputs for use with receivers having a subwoofer or stereo preamp
output that do not contain their own low-pass crossover. There is also a
dedicated LFE input, if your receiver has an LFE output and a built-in
- High-Level Inputs/Outputs: The powered subwoofer has binding-post
terminals for the speaker-level inputs and outputs. The subwoofer's low-pass
filter sends bass frequencies (based on the setting of the filter) to the
subwoofer and high/midrange frequencies to your speakers connected to the
sub's speaker level outputs. You should set you receiver's front speaker
setting to Large.
Auto On/Off: The Focal powered sub's Auto On/Off feature
will switch the powered subwoofer On and Off automatically by signal detection.
The powered subwoofer will automatically switch on as soon as an audio signal is
detected. The powered sub will enter "standby" mode when there has been no
signal activity for 3 minutes or more.
Applications: The Focal SUB300P powered sub is ideally suited to
complement Focal's Chorus series loudspeaker line-up and other brands of
speakers, adding deep and rich bass extension to your movies and music
Placement Options: The powered subwoofer can be placed
almost anywhere in the room as bass sound is largely non-directional. For best
results, place the subwoofer on the same side of the room as your front
speakers. Corner placement will increase the powered subwoofer's output.
