Flush Mounting to Wall
•flush-mounting minimizes diffractions
•eliminates back wall reflection
•boosts speaker output
•removes the front baffle effect
•low frequency room resonances need to be attenuated
The half space loading generated by the front baffle is far from ideal. The baffle edges produce reflections because of diffraction of the sound energy at these edges. These degrade the transient response and directional characteristics of the loudspeaker system.
Frequency response dip caused by a reflection
Considering the practical control rooms, a free standing speaker is always surrounded by walls that will generate reflections. These walls act as acoustical mirrors to the speaker's radiation, enhancing or canceling the direct sound, depending on the phase difference between the reflection and the direct sound at the listening position.
