Example 3A: Using Surface-Mounted Bass

Modules for a Foreground System in an L-

shaped

100'x75'x13' Room

One design option is

exercised using ten

(10) satellites

mounted as shown in

the figure to the right,

at a height of 12.5

feet and a pitched of

10°. This design

requires using five

modules. Tapped at

200 W, this system

delivers 89-92 dB-

SPL. Amplifier power

of 2000W is recom-

mended for this

system.

Accessories

Example 3B: Using Flush Ceiling-Mounted Bass

Modules in a Room Like Example 3A

A second option

uses the same

number and

location of

satellites as in

3A and the same

number of bass

modules. But

here the mod-

ules are flush

ceiling-mounted

at least 3-4 feet

off the center

line.

Examples…

A single FreeSpace 3 system

tapped at 200W requires an

amplifier that can deliver 200W

continuous with (3dB) peaks.

To ensure proper amplification for

a system designed with FreeSpace

3 speakers:

1. Add the wattage taps of the

speakers to calculate the total

number of watts drawn from the

line.

2. The continuous output power

rating greater than the wattage

drawn and capable of handling

peaks of twice the wattage

drawn. Allowing at least 25% of

continuous power headroom is

recommended.

Example

A FreeSpace 3 system tapped at

100W requires an amplifier with at

least 100W of continuous output

power.

Allow for 25% headroom in back-

ground music systems. A 125W

amplifier is recommended.

For foreground music systems -

100% headroom is recommended.

A 200W amplifier should be used.

The FreeSpace

®

3 speaker ceiling

adapter kit allows for suspending the

module above the ceiling, using an

exit grille like the one used with the

Model 8.

Black and white satellite extensions

are also included (shown at the lower

right of the figure) in the kit, to allow

for ceiling mounting the satellites,

too.
