ers be mounted closer than 2' (60cm) from side walls or ceiling,
the proximity of the surface can result in a response “bump”
between 50 and 200Hz. This can cause the loudspeakers to
sound “boomy.” The “Wall Distance” switch flattens response

response for more lifelike sound. Set the switch accordingly,
<2' (60 cm) or >2' (60 cm).
