System
Genelec LSE series active subwoofers are
powerful and precise bass monitoring tools
for modern 6.1 or 5.1 channel Surround
Sound as well as traditional Stereo systems.
With their 19 Hz lower cut-off frequency, high
sound pressure output capability and versa-
tile bass management systems, they can be
adapted to all low frequency monitoring situ-
ations.
The ampli fier unit integrated into the
cabinet contains active crossover filters,
driver overload protection circuits and power
amplifiers. The built-in bass management unit
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
selectable 85/120 Hz low-pass filter and a
0/+10 dB LFE sensitivity switch.
The amplifier has adjustable sensitivity,
bass roll-off and phase matching controls to
tailor the response of the subwoofer to its
environment. An integrated 85 Hz test tone
generator is provided for accurate crossover
phase alignment.
LSETM cabinet construction
These L SE series subwo ofe rs fe ature
Genelec’s new Laminar Spiral Enclosure
(LSETM) bass reflex cabinet. The cabinet
is made of sheet metal rolled into a spiral
TM
shape and clamped between thick MDF side
panels. The spiral forms a seamless, gently
curving reflex tube with excellent laminar flow
characteristics and minimal turbulence noise.
The curved shape also offers excellent struc-
tural stiffness and optimal packing of a very
long reflex tube into a small space.
The bass management unit is mounted
on vibration absorbers, to ensure rattle-free
operation. This results in a robust and reliable
system. The handsome cast-aluminium grille
also functions as a heatsink for the power
amplifier.
Speaker configuration and
positioning
With their built-in bass management unit the
LSE series subwoofers may be used with
other Genelec monitors to extend their low
frequency response and SPL performance.
Two or more subwoofers can be coupled
together via the “SUM OUT” connector if a
higher maximum SPL is required.
The phase correction switch in the bass
management unit allows for the subwoofer to
be freely placed away from the main monitors
without phase cancellation.
Drivers
The 7060B has one 250 mm (10”) cone driver,
the 7070A one 305 mm (12”) cone and the
7071A two 305 mm cone drivers. The drivers
are magnetically shielded long throw types
capable of producing high SPLs.
Amplifier
The amplifiers produce 120, 250 and 500 W of
short term RMS power for the 7060B, 7070A
and 7071A respectively, with very low THD
and IM distortion. Driver overload protection
and power-on signal muting is included in the
amplifier circuitry.
Bass management unit
The built-in bass management unit splits
the six main channel input signals into low
and high frequency components, accurately
dividing the input signal b etwee n the
subwoofer and the main speakers. The
crossover frequency is fixed at 85 Hz. The low
pass section has an adjustable sensitivity,
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
so that the effect of the subwoofer to the
whole monitoring system can be determined.
Balanced XLR connectors are used for the
system inputs and outputs.
A dedicated “LFE IN” input connector
allows easy set-up and accurate monitoring
of the LFE channel in 5.1 and 6.1 channel
surround sound systems. The LFE channel
on the 7000 series subwoofers can be set
to two bandwidths: 19 to 85 Hz or 19 to 120
Hz. If the LFE signal includes higher frequen-
cies than 120 Hz, they can be monitored by
