Wall Mount Speaker System

DESCRIPTION

BS-1034

BS-1034S

FEATURES

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 
speaker. An M4 screw terminal input connector allows easy 
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.

 

• Innovative speaker design

• Low profile

• Beautiful 

d

esign 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
