2) Suitable for speaker power: 400W or lower.
3) Suitable for speaker impedance: 4 to 16 ohms
With 4 jumpers on board to optimise your audio effect: jumper A, B for bass; jumper C, D for treble.
Sweater details:
Jumpers A, B are used to control audio effects of the bass range. A for the lower limit and B for the upper limit of the bass audio range. On some speakers, the speaker will show distortion when the bass is turned up too much. When that happens we remove Jumper As jumper cap to limit the super deep bass to reduce distortion. When we remove the cap from Jumper B, the bass is increased, while the cap of Jumper B is turned on, the bass is reduced. Jumpers C and D are used to control the height range. When the cap is turned on by both Jumper C and D, the sound of the highs is the loudest. When only the cap C is turned on, the treble sound is lower. When only cap D is turned on, further down. When both caps are removed from C and D, there is no treble sound. (In general, you would find your best sound effect sooner or later with the four jumpers. Anyway, all effects still depend on your actual test.)
How to use the splitter plate:
Connect first according to our diagram above (highs, low, input), connect to the speaker, seal air gap, we can start listening to music while optimizing.
Normally we use Jumper A and leave B idle. For Jumper C and D: we need to hear the actual effect of heights. A general formula is: A+D = better bass; A+C = clear treble and bass; A+CD = clear treble and bass (the overall effect tends to treble; AB+CD = more mediant frequency. If the bass effect is unnecessarily high, we can remove cap A. Please tweak until you think the sound is best, and then attach the board to your speaker unit.
