REMOVING THE CLOTH GRILLE

The RTSFX’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.

ROOM ENVIRONMENT CONTROLS

Tweeter Switch (RTSC/RTSFX)

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 (RTSFX)

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).

RTSC/RTSFX THX®Ultra2-certified Performance

For THX® Ultra2-certified performance, use the cloth grille; set the Tweeter Switch (RTSc/RTSFX) to the “normal” position; on the RTSFX, set the Wall Distance Switch to the greater than two feet (>2) position.
