changing the low frequency reproduction bone property, it is possible to change the low
frequency reproduction bone property by changing the low frequency reproduction bone
property from the outside 7- 'from the outside. It is something like 1 ? ░. A conventional K-K
speaker system is configured as shown in FIG. Reference numeral 1 denotes a box main body,
which is provided with 11 Kffi fronts and two breaking holes 2 and 3 on the front, an adsorbent
4 is provided in the inside, and a dedicated speaker 6 is provided on one side 2 of the speaker
mounting hole. A speaker with a drop y-cone is attached to the other Subey self-assembly hole 8
attached. As shown in FIG. 112, the drontoons beaker 6 is supported by the central Ilt damper 11
