The CLA bass uses differential driving technology, which is characterized by dual -sound coil and dual magnetic steel design. It allows the driver to achieve high output at a smaller volume and lighter weight. The sound coil is outside the magnetic steel. The advantage of this design is that it is conducive to the audio coil heat dissipation, so the power bearing capacity is great. Another purpose of differential driving technology is to consider that professional speakers need to be hanged in actual use, or installed on the wall and ceiling through a bracket, and the weight of the unit is reduced. This also means that the weight of the speaker is also reduced, and ait can ensure continuous high output.
