400W Speaker Crossover 2 Way High-Low 4-16 Ohm Frequency Divider for Speaker

How to use the splitter board:
First connect as per our diagram above (Treble. Low. Input). connect to speaker. seal air . begin to hear music while optimize.
Normally we use jumper A and let B idle. For jumper C and D: we need to hear the actual effect of treble. A general formula is: A+D = better Bass; A+C = clear Treble and Bass; A+CD = clear Treble and Bass (the overall effect inclined towards Treble); AB+CD = more mediant frequency. When Bass effect is unnecessarily high. remove cap A. Please optimize think the sound is best. and then fix the board with your speaker unit.

• Jumper A. B are used to control audio effect of bass range. A for lower limit while B for upper limit of the bass audio range. For some speakers. when Bass is turned up too much. the speaker will show distortion.
• When that happens: we remove the jumper cap of jumper A to limit super low Bass to bring distortion lower. When we remove the cap of jumper B. Bass is increased while cap of Jumper B is on. Bass is decreased. Jumper C and D are used to control Treble range. When cap of both jumper C and D are on. the sound of treble is loudest.
• When only cap C is on. the treble sound is lower. When only cap D is on. further lower. When both caps of C and D are removed. there is no treble sound. (Generally speaking. with the four . you’d sooner or later find your best sound effect. Anywya. all effects still depend on your actual test.)
