SYSTEM
The Genelec 1034BC is a dedi-
cated center channel speaker for
three channel (LCR) and Surround
Sound systems. Its cabinet has
been designed for optimum placement in the limited space above or
below of a video monitor or screen.
It can also be used in vertical orientation, on either side of a video
monitor or screen.
As its name suggests, the Genelec
1034BC is best suited for use as a
center channel speaker with a pair
of standard Genelec 1034B monitoring systems. The 1034BC
employs the same mid, treble and
bass drivers and Directivity Control
Waveguide as a standard 1034B
and the amplifier unit is also the
same to ensure complete tonal compatibility.
Genelec 1034BC is a three-way
active monitoring system including
magnetically shielded loudspeaker
drivers, speaker enclosure, multiple power amplifiers and active,
low signal level crossovers.The
1034BC is recommended to be flush
mounted into the control room wall,
but it can also be used as a freestanding monitor.
capable of driving a stereo system
to peak output levels in excess of
125 dB SPL at 2 m with program
signals. Versatile crossover controls allow for precise matching of
the speaker system to different
acoustic conditions. The system
can be used both in vertical and
horizontal orientations by simply
rotating the DCW unit.

crossover filters, power amplifiers
and driver units.
The separate amplifier unit is built
into a rack mount chassis for easy
fitting into a standard 19" 7U equipment rack. A 10 meter cable set to
connect the amplifier and speaker
is supplied with the system.
The unique Directivity Control
Waveguide (DCW) Technology provides excellent stereo imaging and
frequency balance even in difficult
acoustic environments. The fast
acting, low distortion amplifiers are

The reference axis lies between midrange and tweeter drivers.
AMPLIFIERS
The treble, midrange and bass am-
plifiers each produce 120 W, 350 W
and 2 x 400 W respectively of short
term power with very low THD and
IM distortion. Special attention has
been paid to electronic design to
ensure the highest subjective sound
quality currently possible. The system incorporates special overload
protection circuitry for the drivers.
Thermal protection is also included
for the amplifiers.
DRIVERS
The bass frequencies are repro-
duced by two long throw 305 mm
(12") bass drivers loaded with a 160
liter vented box. The -3dB point is
32 Hz and the low frequency response extends down to 28 Hz (-6
dB). The midrange frequencies are
reproduced by a proprietary 130
mm (5") direct radiating cone driver
loaded with a DCW. The high frequency driver is a 25 mm (1") metal
dome also loaded by a DCW, with
an upper -3dB point at 22 kHz.
The 1034BC is magnetically
shielded in order to minimise interference with video monitors.
CROSSOVER FILTERS
The active crossover network con-
sists of three parallel band pass
filters, with crossover frequencies
at 400 Hz and 3.2 kHz, and a
common balanced input stage. All
the filters are aligned for equal phase
and group delay characteristics and
are acoustically complementary.
The filter slopes are 24 dB/octave.
To adjust the balance of the drivers
to suit a particular acoustic environment, bass midrange and treble
level controls are included, which
adjust the output in 1 dB steps. In
addition, low frequency 'roll-off' and
'tilt' controls are present, to allow
further refinement of the system
response.
DCW TECHNOLOGY
The revolutionary Directivity Con-
trol Waveguide Technology is a
means of vastly improving the performance of a direct radiating
multiway loudspeaker in normal listening conditions.
The basic idea is to match the
different drive units precisely, both
in terms of frequency response and
directivity. This will result in a
smoother and virtually uncoloured
off-axis response of the system.
Also due to improved directivity
control especially in the midrange
and high frequencies, more direct
sound and less early boundary reflections are received at the listening
position. This gives a more accurate stereo imaging and makes the
system less sensitive to differing
control room acoustics than any
conventional direct radiator design.
The DCW Technology improves
drive unit sensitivity from +2 to +6
dB thus increasing the system's
maximum sound pressure level.

Order Code
The curve group above shows the horizontal directivity characteristics
of 1034BC in its vertical configuration measured at 1 m.The lower
curve is a 1/6 octave power response measurement, derived from 144
individual directivity measurements.
The curves above show the effect of the 'bass', 'mid' and 'treble' level
controls, and the 'bass tilt' and 'bass roll-off' controls on the free field
response, measured at 2 m. Note that the free-field mid-range ripple is
substantially reduced when the speaker is flush mounted as recommended.
