Active Subwoofer 7050A
System
Genelec 7050A active subwoofer is a very
compact low frequency loudspeaker,
incorporating all the amplier and crossover
electronics needed to combine it with Genelec
1029 or 2029 series loudspeakers. Adding
the 7050A to a 1029/2929 system creates a
compact neareld monitoring system capable
of a at frequency response from 38 Hz to 20
kHz (± 2.5 dB).
The amplier unit, which is integrated into
the cabinet, consists of the active crossover
lter, driver overload protection circuits and a
power amplier. The subwoofer has two input
connectors and adjustable sensitivity. This
provides great exibility.
LSETM cabinet construction
Like the larger Genelec 7000 series
subwoofers, the 7050A features the new
Genelec Laminar Spiral Enclosure
bass reex cabinet. The cabinet is made of
sheet metal rolled into a spiral shape and
clamped between thick MDF side panels. The
spiral forms a seamless, gently curving reex
tube with exellent laminar ow characteristics
and minimal turbulence noise. The curved
shape also offers excellent structural stiffness
and optimal packing of a very long reex tube
into a small space.
The amplier unit is mounted on vibration
absorbers, to ensure rattle-free operation.

This results in a robust and reliable system.
The handsome cast-aluminium grille protects
the magnetically shielded 8 inch driver.
Driver
The 7050A is equipped with a 200 mm (8”)
magnetically shielded long throw cone driver
capable of producing SPLs up to 105 dB in
half space.
Amplier
The amplier produces 70 W of output power,
with very low THD and IM distortion. It is
mounted on thick aluminium, which provides
excellent heat dissipation. Driver overload
protection and power-on signal muting is
included in the amplier circuitry. This makes
the system immune to overloads and spurious
signals. Power-on signal muting electronically
disconnects the drive unit when the power is
turned on. The amplier also incorporates
thermal overload and short circuit protection.
Crossover lters
The active crossover contained within the
amplier unit lters the input signals. This
accurately rejects the higher frequencies that
the monitors reproduce, and allows the lower
frequencies to pass. The sensitivity can be
attenuated by from 0 dB to -18 dB for easy
level matching with the main speakers for

Balanced XLR female connectors are used
for the system inputs. This allows for easy
integration with Genelec 1029 and 2029
series active monitors.
Cabling and connections
Figure 3 shows the 7050A and the 1029A’s.
Figure 4 shows how the system should be
cabled. The input to the 1029/2029 monitor
is made by an XLR connection. This can be
either balanced (e.g. output of mixing console)
or unbalanced (e.g. output of CD player).
The subwoofer output of the 1029/2029, and
hence the inputs to the 7050A are balanced.
The wiring diagrams for these congurations
can be found in the operating manual which
is supplied with the systems.
Why a subwoofer?
For applications, such as computer
multimedia work and most types of near eld
monitoring, the 1029/2029 is an appropriate
monitor system. However if lower LF cutoff
and more SPL are required, for example in a
home theatre system, the 7050A subwoofer
has been designed for this requirement.
The 7050A has been specically designed
to complement Genelec 1029/2029 series
active monitors. When combined they give
a frequency response comparable to some
larger Genelec monitors - one of the
