ROOM ENVIRONMENT CONTROLS
Tweeter Switch (RTS
C
/RTS
FX
)
If your listening room is very reflective, with smooth sheet-
rock walls, hardwood floors, and non-cushioned furniture,
the sound will be overly “bright” and unnatural. Engaging
the tweeter attenuation feature a Tweeter attenuation fea-
ture. Selecting the “cut” setting compensates for the effect
of reflectivity in a hard room. Tweeter attenuation flattens
room response, without hindering higher frequency response,
for warmer, more realistic sound and more accurate imaging.
Wall Distance Switch (RTS
FX
)
In-wall and in-ceiling loudspeakers excel when placed more
than 2'(60cm) from side walls. If position limitations demand
that in-wall loudspeakers be installed closer than 2'(60cm)
from side walls, the proximity of the surface can result in
a response “bump” between 50 and 200Hz. This can cause
in-wall speakers to sound “boomy.” The Wall Distance Switch
flattens response and tunes out “boominess” without sacrific-
ing deep bass response, for more lifelike sound.
If placement is closer than 2' to a wall:
Engage the Wall
Distance Switch (“Wall Dist.”) to match the <2' setting.
Recommended speaker distance from side walls is 2 feet
(60cm).

REMOVING THE CLOTH GRILLE
The RTS
FX
’s cloth grille fits tightly to the speaker Baffle.
If you use the cloth grille, take special care when removing it.
Important Note: Never use any tool, such as a paperclip,
to remove the grille, as this could tear the cloth.
Instead, use your hands (after you’ve washed them), grasping
the grille frame near two of its mounting cups and pulling the
frame firmly away from the baffle.
