How to flush mount Zenith speakers

During the recessed installation process, it is very important that the front panel of the speakers be on a plane with the front wall as shown in the picture below, not protruding out or retracting in.

Some engineers like to use a sturdy concrete structure as the base of the speaker, which works well to secure the speaker firmly to the front wall. But this approach is more costly. The floating recessed mounting structure pictured below is also a good alternative. This structure starts by placing the speaker on top of rubber springs that isolate the vibrations of the cabinet from the structure of the room. The idea is that all sound radiation comes from the cabinet, not from the walls, floors, and ceilings around it.

The battle with the room's inherent acoustic deficiencies

The room's inherent acoustic deficiencies, known as standing waves, are more likely to be excited in a control room with embedded speakers than in a room with freely placed near-field speakers. Standing waves are characterized by a maximum sound pressure level at the surface of the wall. As the wall and the integration of the speaker just has the inherent advantage of stimulating the room longitudinal standing waves. From this point of view, if you want to overcome the adverse effects of standing waves, you need to set up a large number of low-frequency sound-absorbing structures on the side walls, especially the rear wall. This has been proven to be the most effective method.

The side and rear walls are sound-absorbing structures, and the front wall is a hard wall.

Summary

A well-designed flush mounting structure can solve many problems in the process of sound reproduction, making the reproduction more accurate and real. Flush mounting can also minimize the diffraction effect brought about by the edge of the speaker, while eliminating rear wall reflections, increasing speaker output

rate, and eliminating the front baffle effect. In the embedded installation of speakers at the same time, you also need to do the appropriate acoustic treatment of the rear wall.
