吾是wall mount系半 mount，方便維修
真正wall mount系
speaker面平水wall，就冇diffraction，成幅
wall 系，形成半球形發声

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.

flush mount 系好高技朮含金
HK包括Dragon studio都冇津照真正flush mount
去做，卑盡叫佢wall fit
