Variable Boundary Gain Compensation Variable Boundary Gain Compensation is a filter which can compensate for bass peaking which typically starts around 60Hz and increases downwards. At first, this effect sounds superficially impressive, but listen to music for any length of time and it becomes"boomy"and rather annoying.The effect commonly occurs in smaller rooms and when your listening position is near to a wall, hence the name Boundary Gain Compensation. As with phase adjustment, we recommend you play music or the test frequency files from www.Jamo.com and have a friend turn the Variable Boundary Gain Compensation control, while you sit in the listening area. Then simply adjust it so that when the bass hits the lowest frequencies, there aren't any detectable bass peaks. Cleaning Please use a dust-free cloth to clean the speakers. It is also possible to use a slightly damp cloth for more stubborn marks. Under no circumstances should you use any kind of cleaning agent on, or in close proximity to, these speakers. 19

Variable Boundary Gain Compensation
Variable Boundary Gain Compensation is a filter which can compensate for bass
peaking which typically starts around 60Hz and increases downwards. At first,
this effect sounds superficially impressive, but listen to music for any length of
time and it becomes “boomy” and rather annoying. The effect commonly occurs
in smaller rooms and when your listening position is near to a wall, hence the
name Boundary Gain Compensation.
As with phase adjustment, we recommend you play music or the test frequency
files from www.Jamo.com and have a friend turn the Variable Boundary Gain
Compensation control, while you sit in the listening area. Then simply adjust it
so that when the bass hits the lowest frequencies, there aren’t any detectable
bass peaks.
Cleaning
Please use a dust-free cloth to clean the speakers. It is also possible to use a slightly
damp cloth for more stubborn marks.
Under no circumstances should you use any kind of cleaning agent on, or in close
proximity to, these speakers.
