andbroadbandwidth.
The10294is
idealfornearfieldmonitoring,
mobile vans, broadcast and TV control
rooms, surround sound systems, budget
homestudios,multimedia
applicationsand
also for use with comouter soundcards.
As an active speaker,it containsdrivers,

provides

the bass resoonse
of the 1029A's can be
extendedwith a Genelec7050A or 70604
subwoofer.
Integrated
Construction
As the amplifiersarebuiltintothespeaker
enclosure,theonlyconnectionsrequired
are
the mainssupply
and the line level input
signal,makingthe 10294very
easyto set
upanduse.Theintegrated
designallowsthe

effectsofcomponenttolerances
andensures
consistent
quality.
Thecastaluminium
cabinet
has roundedcorners and a hard-wearino
painted
outer
surface.
Drivers
The bassfrequenciesare reproduced
by a
130mm (5")
bassdriver
mounted
in a 4.5
litrevented
cabinet.The -3 dB ooint lies
at
68 Hz and thefrequencyresponse
extends
downto65 Hz(-6
dB).
The highfrequency
driveris a 19 mm
(3/4")
metaldome.
Uniformdispersioncontrol
is achieved with the revolutionaryDCW
Technology
pioneered
by
Genelec,
whichhas
also resultedin perfect phase and delay
uniformityatthecrossover frequency.
Magnetic
shieldingis standardon the
10294.Shieldingis vital for applications
suchas videopostproduction,
where
stray
magneticfieldsmust
be
minimized.
Crossover

crossover
network
consistsoftwo

bandpassfilters.Acoustically,thefil-
tersarecomplementaryandthe

is 3.3 kHz.The active crossovercontrols
('treble
tilt',
'bass
tilt'and'bassroll-off')
allow
this speaker to be exactlymatchedto any
application.
Amplifiers

the speaker
enclosure.The bass and trebleamolifiers
both
