System
The Genelec 7073A active subwoofer is a
powerful and precise bass reproduction tool
for large Surround Sound or Stereo installa-
tions. Its 19 Hz lower cut-off frequency and
124 dB sound pressure output capability
are sufficient to handle the most demanding
high SPL applications. All electronics are
integrated into the subwoofer cabinet: active
crossover filters, driver overload protection
circuits and power amplifiers. The built-in
bass management unit on the 7073A has six
signal input and output channels (L/C/R Front
and L/C/R Rear), LFE input and summed
signal output connectors, providing great
flexibility and easy connection. The discrete
LFE signal input is equipped with a select-
able 85/120 Hz low-pass filter and a 0/+10 dB
LFE sensitivity switch. An integrated 85 Hz
test tone generator is provided for accurate
crossover phase alignment.
The 7073A also features adjustable Sensi-
tivity, Bass Roll-Off and Phase matching con-
trols to tailor the response of the subwoofer
to its environment.
Cabinet construction
The speaker cabinet of the 7073A is a bass
reflex design constructed of MDF and heavily
braced to eliminate structural resonances. The
black paint finish is rugged and stratch-resis-
tant. The long, straight bass reflex tube runs
along the rear wall of the speaker cabinet and
opens on the connector panel side.
The crossover electronics are mounted
on vibration absorbers to ensure rattle-free
operation. The protective cast-aluminium
grilles also function as heatsinks for the
power amplifiers.
Drivers
The 7073A has four 305 mm (12”) cone driv-
ers. The drivers are magnetically shielded
long throw types capable of producing high
SPLs.
Amplifier
The amplifiers on the 7073A produce a total
of 1000 W of short term RMS power with very
low THD and IM distortion. Driver overload
protection and power-on signal muting are
included in the amplifier circuitry.
Bass management unit
The built-in bass management unit of the
7073A splits the six main channel input sig-
nals into low and high frequency components,
accurately dividing the input signal between
the subwoofer and the main speakers. The
crossover frequency is fixed at 85 Hz. The
low pass section has an adjustable sensitiv-
ity, to allow easy level matching with the main
speakers. The six high pass sections have 0
dB passband gain. The high pass filters can
be bypassed using an optional bypass switch
