actually singing in your room? If there is too much volume the 
artist will appear too big and the opposite is true for too little 
volume. If the volume is set correctly and the image is still too big, 
toe the speakers in a very slight amount or place them closer 
together and re-listen. Repeat this process till you have it right.  

If the voice is too low in height, turn the midrange control to the 
next highest position and the image of the voice will move upward. 
There are many solo vocal recordings where the singer is recorded 
using a microphone hung above head height. In this case, it is 
correct for the system to portray a singer that seems to be singing 
from a pit in between your loudspeakers. 

If you have the speakers too close the front wall, and you are not 
getting enough front to back depth (the singer not appearing behind 
the speaker enough) pull the midrange tweeter panels away from 
the front wall a little bit at a time. If you do not have them pulled far 
enough away, you may not have enough front to back depth. If 
you get the speakers much beyond 1/3 of the way into the room, 
it is unlikely that pulling them further away is reasonable. 

Too much absorption on the wall behind the speakers will also 
result in less depth in the soundstage. The G2

jr

 requires a 

relatively “live” front wall. 

Find the best compromise for your room, your tastes and your 
space requirements. If the speakers are too far apart you will lose 
the side image and the image density in the middle of the 
soundstage will be too diffuse. If the speakers are too close 
together you will have too small a center stage, and you may find 
that the edges of the soundstage collapse inwards.  

We recommend you begin somewhere between six to seven feet 
apart as measured from centreline of tweeter to tweeter. And then 
move the speakers apart small increments at a time as you tune 
the system. They seldom work well closer than six feet apart or 
much more than nine feet apart. 

If you are not getting proper focus of the soundstage, you may 
angle the midrange panels from 1 to 3 degrees (but no more) 
inwards towards your seating position until you have a properly 
defined soundstage image. The usual reason that you will want to 
do this is that you have a 

“W” soundstage. The sound images are 

most dense (or focussed) in the middle, and then dense around
