There are lots of it. Many are listed on the speakers page of my
website. Come to a visit:

I have some designs of my own, but they're suited for P.A. speakers made
here in Brazil (Selenium, Snake and the like), think you won't find them
easily in your country. If you live in USA or some countries in Europe,
however, you can find in some stores.

It's possible to use a passive crossover network, but you'd better not.
If you want good performance, you MUST use an active crossover and
another amplifier to do the job.

At this another page, still in my site, you'll find many links with good
schems:

It makes sense. In fact, I can hear it.

I'd love, but my poor english doesn't helps...  Maybe another sound guy
or audiophile here can tell you better. Otherwise, I can point you to an
interesting site. Just give me time to dig it out.
