Components
Subwoofer
The L.U.C.A.S ALPHA subwoofer's housing is split
into two chambers. The front chamber serves as the
speaker cabinet for the 18" direct-loaded woofer,
which has a power handling capacity of 1,200 watts
and a nominal impedance of 4 ohms. The active
electronic circuitry, the power unit, DDO™ digital
controllers and Class D power amps are housed in a
separate compartment at the rear of the cabinet.
Satellites
Satellites are loaded with a 12" HK Audio Custom
speaker and a 1.4" compression driver with a
60° x 40° BEM CD horn. They are rated for
400 W RMS power handling capacity and a nominal
impedance of 8 ohms.
The newly developed, integrated HK AUDIO Duo-
Tilt™ 3/7 pole mount allows sound energy to be
utilized far more efficiently. It minimizes annoying
ceiling reflections, thereby achieving a clearer,
tighter, and more focused sonic image. The cabinet
is always stabilized at its center of gravity – no
wobbling, tilting, or unintentional turning.
More about limiters
Limiters are designed to protect power amps and
connected speakers from harm. The functionality
and response of a limiter is determined by para-
meters called attack time, threshold and release
time. Adjusting these parameters incorrectly can
degrade the soundscape and elicit dynamic distorti-
on. At peak volume levels, for example, vocals may
fail to cut through the mix and instruments that are
played percussively lose their punch and dynamics.

2 Transport

To transport the system, simply set the subwoofer
on its casters and place the satellites onto the sub-
woofer with the foam rubber grille side facing down.
Secure the satellites, for example, using a locking
strap. Use original L.U.C.A.S ALPHA protective
covers to gear up your personal system for the rigors
of the road. Amply padded and protected against
moisture, your L.U.C.A.S ALPHA is sure to deliver
satisfying performance for a long time to come.
HK AUDIO limiting technologies are more than
merely technical tools serving to protect compo-
nents. We put a premium on authenticity, that is,
retaining an audio event's true dynamics. This
explains why our limiters are first and foremost
acoustical tools, though they of course also protect
the system.
