Inwall LCR Speakers can be used in any position of a home theater 

speaker system. A single Inwall LCR Speaker can be used for the 

front center channel, or a pair can be used for left and right in the 

front or rear of the system. 

Using as a Center Channel Speaker

Inwall LCR Speakers have been designed to blend seamlessly 

with all Proficient inwall and ceiling speakers. For center channel 

applications, install the Inwall LCR Speaker horizontally into the 

wall as close to the screen as possible. This most often means 

it will need to be installed just above or below the television. 

Vertically lining it up with the left and right speakers while not 

necessary, will improve the performance. (See Diagram 1)

Using as Front Left and Right Speakers

When using Inwall LCR Speakers for front left and right speakers, 

position them vertically with the tweeter towards the screen. Align 

them with the center of the screen for optimal results. (See Diagram 1)

The speakers should be placed so that they form an equilateral 

triangle. (See Diagram 2) If the speakers are positioned far away from 

the primary listening area, adjust the pivoting tweeters so they are 

pointed toward the primary listening area. 

Note: 

To avoid possible damage to the pivoting tweeters, read the 

section entitled 

“SPEAKER ADJUSTMENTS”

 in this manual prior to 

performing the tweeter adjustment.
