Now the question arises: how to change the crossover?
Regarding the bass driver:
That part of the crossover that used to serve the two bass drivers previously
needs to be changed as follows:
- The coils' inductance needs to be doubled
- the capacitors' capacitance needs to be halved
- the resistance values need to be doubled
Please bear in mind:
the coils may have a wire diameter that is 30% smaller
the resistors may have half the load-carrying ability or more
Regarding the tweeter:
That part that serves the tweeter remains unchanged with regard to coils
However, the output of the tweeter needs to be decreased by 6 dB. To achieve
this the resistors have to adapted. The picture below shows on the left how
the tweeter and resistors should look like using two bass drivers (please
enter 9999 when no Rp is available, if there is no Rs
please enter 0) and on the right how it should look like with one bass driver.
Just enter the impedance of the loudspeaker and the values of the two resistors
on the left and click calculate.
