step 4 Using the speaker spacing from the
table at right, create a loudspeaker layout on
your room sketch that meets your coverage
requirement.

Distance
Premium 20ft | 6m
Standard 25ft | 7.5m
A. If both room dimensions are less than 30ft (9m),
mark one Satellite location in each corner of the
room.
B. If the room length is greater than 60ft (18m), add
one Satellite for every 25ft (7.5m).

step 5 Using your sketch of the room, create a Bass Loudspeaker Layout with the correct number of
bass modules to meet your Coverage Requirement.
A. Determine the quantity of bass
modules required for your system layout.
