DESCRIPTION

The BS-1034/1034S are wall-mount speakers matched with
a supplied plug-in speaker receptacle, for easy installation. The
10W rated input BS-1034/1034S combine a low-frequency 5" (12cm)
cone-type speaker and a high-frequency balanced dome-type

er. An M4 screw terminal input connector allows easy

speak
connections. The speakers are driven on a high-impedance (100V or
70V) line, with rated inputs. A selectable attenuation function is

provided on the BS-634T. The speaker enclosure’s design proportions

are based on the Golden Ratio (1: 1.618). A low profile blends in well
with room décor. Both vertical and horizontal installations are possible.
Enclosure and grille net colour is off-white, except on the BS-1034S,
which comes with a silver net grille.

FEATURES

• Innovative speaker design

•Low profile

• Beautiful design due to the Golden Ratio (1: 1.618)

• Easy and quick installation

• Thanks to the ingenious location of the TOA logo, the speaker
creates a distinctly different impression depending on whether it is
installed horizontally or vertically.

•Two colours selectable: off-white, which matches any interior style,
and silver, which adds a quality appearance.

• Ideally suited for BGM and announcements

Installation view

Note: As a force of approx. 18 kg (39.68 lb)
is applied to the speaker receptacle at the
time of speaker installation, attach it in a
location durable enough to withstand the
force.
