PJ-304
Projection Speaker System
DESCRIPTION
FEATURES
The PJ-304 are bass-reflex HIPS resin enclosure 5" (12cm) cone-
type projection speakers intended for ceiling and wall installation. The
PJ-304 also includes a balanced dome tweeter. They have an
outstandingly stylish design that is inspired by the finest lighting
fixtures, allowing them to be harmoniously installed with lighting
equipment. They are ideally suited for such applications as BGM and
announcements at airports, subway stations, art museums and
shopping malls. The speakers are easy to repaint, extending the range
of design needs they can meet. A supplied swivel bracket accessory
allows for flexible speaker angle adjustment.
PJ-304 is driven on a high- and low impedance (8) line.
Input impedance is adjustable with rotary switch on the upper side
of the speaker.
•Stylish and outstanding design inspired by the finest lighting fixtures
• Flexible speaker direction adjustment with accessory brackets
• Repaintable
• Input impedance easily changeable
• Ideally suited for BGM and announcements
