The CW170FR loudspeaker is a highly versatile 6” coaxial system 

designed for applications requiring a fire rated ceiling loudspeaker.

Many city and regional authorities are now requiring in-ceiling 

systems to be fire rated. To answer this need we offer the 

CW170FR, which passes UL 2043 and UL 1480 standards. The 

system is enclosed in a 20 gauge steel can that gives it both the fire 

rating properties and a proper acoustical enclosure.  

The speaker unit is a wide range 6 ½” polypropylene coned coaxial 

with a ¾” soft dome tweeter mounting on a pivotable post.  

A sophisticated crossover gives smooth and flat response through 

the midrange and a slight rise through the highest treble frequencies, 

a response suitable for a ceiling speaker. The back can gives full 

isolation from the ceiling environment and allows the system to be 

bass reflex vented for extended bass response.

A low profile perforated grille with removable scrim allows the system 

to be painted any color to further enhance invisibility. Extensive 

mounting bracketry is included for easy ceiling mounting in either dry 

wall or acoustical tiled ceilings. Four “dog leg” style clamps provide 

quick and easy mounting.

A removable steel cover has a clamp suitable for sheathed or 

armored cable. Underneath it is a 4 conductor plug with set screw 

connections.

A 70Volt/100Volt transformer is built into the system. This allows 

multiple speakers to be connected on the same circuit while each 

speaker can be set to an individual volume level. The transformer 

has a multi-position switch with 3 settings for volume (power 

absorbed from the 70/100Volt line) and a 4th position that bypasses 

the line transformer entirely.
