3 way crossover ~ calculator
For the
traditionalist, a 3-way 1st order crossover is used in a 3-way vented enclosure system
which gives good bass response.
The high crossover
frequency should be at least one octave ( f / 2 ) below the resonant frequency of
the tweeter.
The low crossover
frequency should be above the " roll off " ( - 3 db ) of the mid range driver.
The crossover
frequencies must be at least three octaves part.
The reactance of the
components of the midrange interact with the reactance's of the tweeter and bass
components. Thus, the low crossover frequency ( FqL ) and high crossover
frequency ( FqH ) must be recalculated to compensate bringing them closer in
frequency.
If the rated
sensitivity of the tweeter is greater than the woofer, the speaker system will sound too
bright. An attenuation network can be used
to decrease the sensitivity of the tweeter or midrange driver. Remember to use
components that can handle the desired wattage of the system.
