The subwoofer can be set to only allow frequencies above 150Hz, the upper frequency the subwoofer handles, to be distributed to the satellite speakers.

这种特殊的双音圈设计可以保证左和右声道的声音仅仅来自一个音箱，简单地连接左右声道到音箱上的特殊接线盒。如果音箱将在一个普通的立体声设备中使用，连接一个声道就可以了。
 

Both the frame and grille can be painted for perfect integration with the surroundings. We recommend using a spray paint. Separate the grille and the frame from the speaker and paint them individually. Then while the paint on the grille is still wet, gently blow air through the grille from the one side in order to clear all the small metal holes of paint.
