HOW TO PLACE YOUR QBx SURROUNDS
Determining Room Placement
Whether you prefer a more direct surround effect, or the enveloping sense of a diffusion-
oriented surround speaker, proper placement of your QBx Surrounds will enable you to
achieve it. In either case, a few ground rules should suffice for maximum enjoyment of either
surround placement. Take a few minutes to place your speaker systems correctly to ensure
they sound their best.
Height
The QBx Surround speaker produces optimum response along an axis that tilts downward 30
°
(
±
15
°
). Place the Surround speakers at least 5 feet (1.5m) from a floor, yet 12 inches (30cm)
from the ceiling. A fairly high mounting location will aid in sound diffusion and reduce the
chance you will be able to audibly locate the speakers. Increased height will also help to even
out the sound levels across the listening area.
Boundaries
Keep the Surrounds at least 12 inches (30cm) away from an adjacent wall or large obstacle.
Coverage Area
For large areas, multiple Surrounds can be used to ensure even coverage. Use one pair of
Surrounds for every three rows of seats (approximately 10 feet between Surround speakers).
Placement
Please consult the placement diagram. To achieve the greatest sense of sound envelopment,
place the QBx Surrounds to the side of the listening area. If the listening area is against a
wall (for example, if your couch is placed against a back wall), place the QBx Surrounds to
the side of the couch, leaving at least 12 inches (30cm) between the QBx Surrounds and the
back wall.
Back Wall Placement
When placing the QBx Surrounds behind your listening area, keep them as close to the side
walls as possible — but no closer than 12 inches (30cm).
Aiming Your Speakers
For a diffuse sound effect, aim your QBx
Surrounds away from the listening area.
You should not be able to audibly locate
the speakers. Alternatively, aiming your
speakers toward the listening area will
create more focused, directional sound
energy, creating exciting effects in the
surround channels.
