Now the question arises: how to change the crossover?
Regarding the bass driver:
That part of the crossover that serves the bass drivers needs to be changed
- the coils' inductance needs to be halved (therefore, 2 coils are in parallel)
- the capacitors' capacitance needs to doubled (therefore, 2 capacitors are
- the resistance values need to be halved (therefore, 2 resistors are in parallel)
Please bear in mind:
The coils should have a wire diameter that is 1.4 to 1.5 bigger.
The resistors should have double the load-carrying ability.
Regarding the tweeter:
That part that serves the tweeter remains unchanged with regard to coils
However, the output of the tweeter needs to be increased by 6 dB. To achieve
this the resistors have to adapted. The picture below shows on the left how
a system with one bass driver should look like, and on the right how it should
look like with 2 bass drivers. Just enter the impedance of the loudspeaker
and the values of the two resistors on the left and click calculate.
