INTRODUCING X-OVER

It’s original use is to protect the speakers from frequencies it cannot handle.

When used correctly flat f response can be achieved, however only at pre-defined direction. Normally the on-axis (speakers' head on)

•They are first split into 2 categories: - 

1. active
2. passive

•In each category, they have: - 

1. •High-Pass-Filter
2. Band-Pass-Filter
3. •Low-Pass-Filter

They are also split into levels of how fast it cuts out sound i.e. xdB/oct slope, e.g. 

1. 6dB/oct, 
2. 12 
3. 18
4. 24
5. and more, the highest ever heard of is 72dB/oct for non audio application that is.

Finally the slope family i.e. how the slope looks like or behave: -

1. butterworth
2. chebyshev
3. linkwitz riley (most used)
4. bessel
5. legendre
6. and more
