ENGINEERING FEATURES
1.
High Efficiency.
Modest amplifiers or
receivers will be able to produce acoustic
levels normally associated with amplifiers
of substantially higher power ratings.

Video Shielding.
The GHE Series
incorporates magnetic shielding to allow
use on or next to video monitors and TVs.
The magnetic shielding prevents the
powerful GHE speaker magnets from
creating any interference or distortion of
the video picture.

PLACEMENT
The GHE Series cabinet height and driver
placement allow for speaker placement
directly on the floor. The video shielding
allows for the option of placement very
close to a video monitor/TV. When used
as Left and Right Channel speakers in a
Dolby Pro Logic AV system, the shielding
allows the speakers to be placed up
against the sides of the monitor/TV for a
compact AV system profile (see Fig. 1). If
you desire better stereo imaging when
placement allow for speaker placement
directly on the floor. The video shielding
allows for the option of placement very
close to a video monitor/TV. When used
as Left and Right Channel speakers in a
Dolby Pro Logic AV system, the shielding
allows the speakers to be placed up
against the sides of the monitor/TV for a
compact AV system profile (see Fig. 1). If
you desire better stereo imaging when
using your speakers for both video and
audio, the speakers should be moved fur-
ther apart from each other, approximately
2 to 3 feet (.75 to 1m) from the sides of
the monitor/TV.

For the best audio stereo reproduction,
the two loudspeaker systems should be
an equal distance from your listening posi-
tion and separated so that the angle
between them, at the listening position, is
between 40 and 60 degrees (see Fig. 2).
For example, if your listening position is 8
to 12 feet (2.5 to 4 m) from each speaker,
the two systems should be about 8 feet
(2.5 m) apart. Placing the loudspeakers
in corners or against a wall will result in
the strongest (not necessarily the most
accurate) bass. Since the GHE Series are
ported on the front panel so you can place
the rear of the speaker up against a wall
if desired.
