What is the board for the speaker
With a yellow flower or red sandalwood carved into the shape of the whole
This speaker is the stage speaker, if the home use, the speaker power is too large --- amplifier needs a lot of power (horn power 2 times) to push, have enough strength.
However, the power amplifier is only 100W can also push it to listen to music, but the sound of the lack of strength, the best state of the speaker can not play out only.
Plate thickness of 250MM in the MDF can, if your power amplifier is very large (400W-600W), you need more than 300MM thickness, but also the speaker is very strong, the volume of the speaker is large enough, the bass will be better. (Inside and outside the speaker inside and outside, need to use 400 * 200 wood support to strengthen the rigid, to prevent vibration, because the speaker plate can not vibrate, only the speaker inside the air and speakers with vibration, resulting in bass)
200MM above the high-density board can be a little thick panel, do a good job after filling the sound-absorbing cotton
