Before starting the system installation, speaker placement 
needs to be determined. This speaker is designed to 
be mounted in the ceiling in or near the middle of the 
classroom (See figure 1.). The speaker lays directly into the 
acoustic ceiling grid, so locate the tile that is approximately 
in the center of the classroom.

A.  Identify a suitable location for the receiver/amplifier 
 

where it is easily assessable, close to a power outlet,  

 

and at least 6 feet away from any computers.

B.  Remove the ceiling tile from the ceiling that was  
 

identified in Step 1.

C.   Set the ceiling tile on a flat work surface with patterned 
 

side facing down. The dimensions of the CNXQ Speaker 

 

are 2’ x 2’ Using a straight edge, cut 24” off the 

 

end of a standard  2’ x 4’ ceiling tile as shown in Figure 

 

2.  (If the ceiling tile grid is 2’ x 2’, simply remove the 

 

tile and replace with the CNXQ speaker).

D.   Locate the coil of speaker wire. To connect the wire to 
 

the speaker, press down on the colored terminals on 

 

the back of the speaker, insert the wire and release 

 

the tab to clamp it in place. Insert the black wire into 

 

the black-tabbed terminal and the red wire into the  

 

red-tabbed terminal.

E.   Place the other end of the wire up through the opening 
 

in the ceiling and route over the ceiling tiles and back 

 

down the wall to the receiver/amplifier. (NOTE: when 

 

routing wire overhead, it is important to always follow 

 

local building and electrical codes, securing wire as 

 

required). Do not connect the wires to the receiver 

 

amplifier yet.

F. 

If installing the speaker into a 2’ x 4’  suspended  

 

ceiling, snap the included cross tee into the suspended 

 

ceiling grid. Locate the slots in the grid at the center of 

 

the 2’ x 4’ area. Insert one end of the tee, then the 

 

other so it locks into place.

G.   The speaker has an earthquake strap connected to the 
 

back so it can be tied off to the ceiling structure for 

 

safety purposes. Unscrew one end of the wire from the 

 

back of the speaker to be tied off to the ceiling  

 

supports. If local building codes do not require the use 

 

of an earthquake strap and it is not being used, you 

 

should completely remove the strap from the speaker 

 

so that does not create unwanted vibration.

H.   Lay the CNXQ directly onto the ceiling tile grid as 
 

shown in Figure 3. Secure the speaker to the ceiling 

 

with the earthquake strap as required by local  building 

 

codes. Speaker wire should also be secured to the  

 

ceiling. DO NOT lay the speaker wire across the back 

 

of the speaker to avoid unwanted vibration.

I. 

Insert the cut tile back into the ceiling.
