LS1-OC100E-1
Remarks:
•
The height is the distance in meters between floor and loudspeaker.
•
The listening area is 1,5 m above the floor and has a circular shape.
•
The diameter is the line in meters from edge to centre to edge of the listening area.
•
The surface is the dimension in square meters of the listening area.
•
The centre is the point where the loudspeaker perpendicular is positioned above the listening area.
•
Max SPL centre is the total sound pressure level in the centre of the listening area with the loudspeaker
mounted on the specified height and used at maximum power.
•
The sound pressure level at the edge of the listening area is the Max SPL centre minus the chosen maximum
sound pressure variation from centre to the edge of the listening area.
•
The total sound pressure level contains the direct sound plus the first reflection of the sound on the floor
measured in dB SPL.
•
By use of the loudspeaker in indoor applications the maximum sound pressure variation from centre to
edge of the listening area will be equal or less. This depends on the dimension of the room and the amount
of absorption.
•
By use of multiple loudspeakers, approximately +3 dB may be added to the sound pressure level at the edge
region when two listening areas reach each other.
