The Point Series™ loudspeaker range
has been designed with the installation market
in mind. Our goal was to bring the innovative
loudspeaker technology utilized in the world
renowned Adamson touring products, to the
installation industry.
The Point Series has been designed from
the ground up to provide a complete solution
where point source loudspeakers are preferable
over line source arrays. When building a point
source loudspeaker system, one must pay special
attention to not only fidelity, but box output, rigging
versatility and pattern control.
The Point Series is not designed to be
hung in large arrays, where individual boxes can
rely on constructive summation to increase low
frequency output. To ensure the Point Series low
frequency drivers can maintain a high level of
low frequency energy when used as a single
source (or a small 2 or 3 box array), Adamson uses
Advanced Cone Architecture™ with Kevlar cone
geometry and cutting edge Neodymium driver
technologies to ensure maximum SPL with zero
cone fatigue, while providing minimal axial modes
in the passband.
Adamson has been on the cutting edge
of Kevlar cone technology since the mid 80s and
has been using Kevlar cones in the low and mid
band speakers for over 20 years. Combine this

Design Considerations
technology with long excursion Neodymium magnets and you have superior power handling, greater output power and consistently stable low
end, all while keeping weight to a minimum. The low frequency driver baskets in the Point Series utilize enlarged heat sinks and thermal fins to draw
heat away from the coil, lowering it’s operating temperature and minimizing thermal compression.
Since point source loudspeakers cannot sum coherently in the way true line source arrays do (especially in the higher frequencies), they
are best used in single box or small arrays- that are focused on discrete listening areas- to minimize comb filter effects on the listening area. Since
1988, Adamson has pioneered the use of waveguides based on the work of Dr. Earl Geddes. In 1987, Geddes clearly described the geometry of
the Cylindrical, Elliptical Cylindrical and Oblate Spheroidal waveguides. Adamson has further advanced these geometries using technologies such
as Finite Element Analysis and other advanced modeling techniques, stringent testing and evaluation procedures. The use of advanced composite
materials ensure the waveguides and high frequency components are of the highest quality available.
For precise aiming and control, and to ensure as little high frequency overlap as possible, the Point Series range comes equipped with a rotatable
wave guide, that is available in three different coverage patterns to give the sound designer a number of options to achieve coverage where they
