Preamp Electronic 2 Way Crossover Board Audio Speaker Frequency Divider Board 72hz-7230hz Linkwitz-Riley Home Theater

This is the biggest highlight of the work is that you can change the crossover point of the two-way crossover board without replacing components. This is a great convenience for friends who have difficulty determining the crossover point of their speakers. You can use it to easily adjust the crossover frequency of the board output,listen carefully,and find the best satisfactory crossover point,no longer tangled with the inappropriate crossover point. (A digital multimeter,plus simple calculations (can provide you with calculation tool software and paper instruction),just adjust the resistance value to the calculated value,accurate to HZ)
