Hi
I'm curious as to when a HPF and Lpf should be used. To elaborate, I understand that a hpf should be used to stop a sub trying to repordu e frequencies beyond its capability but also with an LPF to restrict the upper limit. However my question is this: do I need an lpf/hpf on kick bins where a xover is used as surely the xover points would act as hpf and lpf?

Yes they do. That's EXACTLY what a crossover is, a bunch of HPF, LPF, BPF all in one box so you can adjust to your liking.

so I don't need to set a separate hpf or lpf filter as well as the xover points?

If you have an active crossover it will be built in. Although I'm not sure if all of them have a low pass for the super high frequencies... but still 99% of them will have most of the functions you want and the more you require from said cross over the more you will invest in "bigger and better"

Basic analogy crossovers will have very very basic 2 or 3 way operation. With the cut offs on a dial and "sub sonic" filters on a button to cut off ultra low frequencies.

When you switch to a digital crossover or digital speaker processor (DSP) as they are more commonly known you will find things like limiters and EQ also built in to try to obtain the most from your boxes without loads of outboard equipment needed.
