slope of the tweeter in order to compensate for

varying room acoustics.Use the Average position

for rooms with a reasonably balanced combina-

tion of hard reﬂective surfaces (sliding glass doors

and bare walls) and soft absorptive surfaces (thick

carpeted ﬂoors and overstuffed furniture). The

Reverberant position is meant for rooms with an abundance of hard sur-

faces,while the Damped Room setting raises the tweeter's output to coun-

teract the effect of an overly absorptive,acoustically"dead"room.

Boundary Compensation

the "On" position adjusts the lower frequency out-

put to compensate for the typical sound colorations

caused by placing the speaker very close to a large

surface,such as a TV screen,a wall,or on a shelf in an

enclosed entertainment unit.If your FS-4000 speaker

is mounted as described above, you may prefer its

sound when the Boundary Compensation controls are engaged.Conversely,

if it is free-standing, away from large surfaces (such as when the speaker

is placed on a stand shelf, away from other large surfaces), you may prefer

the sound with the position in the"Normal"position.

In all cases,we recommend you try both switches in their various positions

and use the settings that sound best in your particular room.Note that the

settings of the Left,Center,and Right speakers may differ from each other.

System Setup When Using a Subwoofer

Some older surround sound decoders and receivers offer a choice of "Nor-

mal" or "Wide-band" modes for the center channel speaker. The FS-4000

speaker is designed to be used in the Normal mode.

Modern digital processing multi-channel systems provide a Bass Man-

agement menu, which typically requires you to select between "Small" or

"Large" speakers during system set-up. When using this speaker with a

dedicated subwoofer, please set all the speakers on the receiver's set-up

menu to Small.

Many of the newer surround receivers and processors give you a choice

of subwoofer-to-satellite crossover frequency. If yours does, we recom-

mend that you start with a setting of around 80Hz for the smoothest blend

between the subwoofer and the FS-4000.

System Setup Without a Subwoofer

For some listeners,a full home theater setup with a separate subwoofer and

rear surround speakers may not be feasible or desired.In that case,the FS-

4000 will provide high quality sound all by itself—far better than the small

speakers built into most televisions.In those situations,we recommend you

set your surround sound receiver's set-up menu to"Subwoofer—No, " and

"Surround Speakers—Off. " Set this way, most receivers will blend some

of the rear channel surround information into the front channels, giving a

more spacious sound.

ADVANCED USER SETUP: For even better results, if your surround

receiver has an adjustable subwoofer crossover frequency, select

"Subwoofer—Yes" (even though you are not using a subwoofer) and

adjust the subwoofer lowpass control to 60Hz. That way, all the bass

from 60Hz and above will be sent to the FS-4000, which will result in

a full-bodied, credibly full-range sound to be reproduced by the FS-

4000, while at the same time, preventing the very low bass signals

(below 60Hz) from overdriving the receiver's ampliﬁer section at high

output levels.
