1.2 Overview the ALIS 15
Line source arrays units are tightly focused in the vertical dimensions but spread sound
widely in the horizontal dimension. These coverage characteristics reduce its ability to be used
as individual units. In order to cover the requirements for smaller array configurations and
shorter throw distances but with the same quality standards as set a line source, led to the
design of ALIS Series.
ALIS15 loudspeaker is a 2-way full range, "Adaptative
Loudspeaker Integrate point Source” which generates a
constant curved wavefront of 40º x 75º suited for a wide
range of applications.
The ALIS15 cabinet is driven by a 15-inch long
excursion cone driver in a vented-box and one high
frequency 3-inch voice coil, 1.4-inch throat diameter
compression driver with a constant-Q horn ensuring equal
tonal balance when moving outside of the intended
coverage pattern, providing a natural and exceptional
sound projection and high SPL with perfect acoustic
coupling.
ALIS15 is designed with a trapezoidal shape for
lateral coupling of adjacent cabinets. Can be deployed in
tightly packed array clusters to deliver extensive coverage
with few elements which is proportional to the number of
units in the array.
Its wide operating frequencies range of 48 Hz to 20 kHz at reasonable levels is ideal for
applications where sub is not required.
While line source array uses variable curvature arrays to create an isophase wavefront
in the vertical plane, ALIS15 are optimized for horizontal installations but also can be operate
vertically when necessary generating a modular, constant curvature wavefront. This line source
deliver remarkable acoustic properties and unmatched versatility for applications including FOH
L/R systems, central clusters, side-fill monitors, distributed systems and complementary fills.
Constructed of premium birch plywood, the durable enclosure is coated with polyurea
paint, hard-shell finish. A strong, hi-perforated steel grille with an acoustically transparent cloth
backing provides protection for the drivers.
The ALIS15 offer extremely easy-to-use rigging, making the system highly versatile
from touring, rental and fixed installations. ALIS15's sides include a couple of aluminium rail
that allow the unit to be easily linked with other ALIS15s in arrays by means of TALBX15 bar.
The optional THV-ALIS15 pickup plate allows lifting ALIS15 horizontal arrays of up to four units
with uptilt or downtilt from a single hanging point; two pickup plates can lift arrays of up to six
units from a single hanging point or motor using the TecB004 Universal Fly bar. The Optional
THF-ALIS15 plates to join the units in fixed installations are available.
The Optional TTG-ALIS15bar suspends vertical arrays of up to six ALIS15s.
Other options include weather protection and custom colour finishes for fixed
installations and applications with specific cosmetic requirements, TWD-ALIS15wooden dolly
board for moving the enclosure and protecting the front grill during transport and storage and
