Front Speaker Toe-In
“Toe-in” refers to the angling of the speaker systems toward the listener location. Toe-in is a
matter of taste. As the degree of toe-in increases, the stereo effect becomes more direct-
sounding, like a pair of headphones. Speakers not toed-in will give a more diffuse sound with a
less defined central image.
Location Affects Bass
As speakers are moved closer to rigid room boundaries — the walls, the floor, and the ceiling —
the deep bass part of the sound range is accentuated. However, if speakers are too close to the
room boundaries, particularly corners, the bass output can be uneven. Experiment until you
find the best overall sound for your room. Choose a musical selection with a strong, continuous
bass line. Repeat a short section until you have a firm impression of it in your mind, then try
another speaker location. Repeat this process until you are content with the bass response you
are getting. Moving your listening position will affect the sound as much as moving the
speakers. Try different listener locations as well as speaker locations.
Surround Speaker Placement
When the QBx 20 Monitor or QBx 15 Mini is used as rear channel surround speakers, they
should be placed where they will produce a diffuse sound field. Your attention should not be
drawn to the speakers, nor should you be able to audibly locate the speakers.
Mount the speakers above the listener
location.
The speakers should be to the sides of
or behind the listener location.
These placement recommendations
minimize the chance you will be able to
audibly locate the speaker. Setting the
front-to-rear balance of the system is also
very important. Many audio/video
components have built-in signal generators
that can help you set the proper balance.
See the instruction manuals for your
associated components for more informa-
tion.
