Introduction
The Hemispherix AS and A20 are in-ceiling
loudspeakers featuring fully sealed back-boxes
to control and maximise bass response, whilst
keeping out dust and other ceiling inhabitants.
The Hemispherix A20 employs an acoustically
optimised front baffle angled at 20 degrees,
allowing its sound output to be projected
towards your primary listening area.
The Hemispherix AS employs a flat front baffle
for uniform sound coverage in all directions
The Hemispherix SPS features a stereo pair
of inputs and a slim semi-open back box,
providing a stero effect from a single source
(figure 1).
Applications best suited to Hemispherix AS
The wide uniform coverage of the Hemispherix
AS makes it the ideal choice for 2 channel stereo
and background music applications. Its uniform
coverage is ideally suited to any applications
where the listening area is not confined to a
specific part of the room. For example, hallways,
dining rooms, office spaces, bedrooms and
multipurpose rooms (figure 2).
Applications best suited to Hemispherix A20
The ability of the Hemispherix A20 to project
sound toward your primary listening area makes
it ideally suited to home cinema applications
(figure 3). Dialogue will become more articulate,
music will have better definition and surround
effects will become more involving and
realistic. The A20's ability to direct more
sound towards the listener results in less
sound reflecting off walls and other surfaces
in the room, creating a clearer, more three
dimensional soundstage. The A20 may also
be useful for background music applications
where the speaker must be placed near a side
wall for aesthetic or structural reasons. In this
application the A20 can be used to project
the sound towards the centre of the room.
Applications best suited to Hemispherix SPS
The Hemispherix SPS is perfect in small rooms
where there is difficulty fitting a stereo pair of
loudspeakers (figure 4). It can also be used
where there is limited ceiling height.
If desired, two Hemispherix SPS loudspeakers
may be wired together in parallel, or a single
Hemispherix SPS may have both inputs wired
in parallel from a single output.
