Need Inexpensive Crossover

I'm using Monitor Audio GR-10 bookselves and a Klipsch powered subwoofer. Right now I'm running them both full range - and using the low pass on the crossover to have it kick in at about 80hz.

What I want to do is to roll off the low end on the bookshelves - as the bass sounds a bit too muddy at higher volumes (and just send the higher frequencies to the bookshelves - say above 80hz)...... and then just send the low frequencies (that aren't being sent to the bookshelves) to the sub (and probably not use the subs lowpass filter at all).

I know that crossovers can get to be pretty pricey, as all high end audio can. However, right now I'm a bit tapped out on the high end audio budget... and need something that will do for the moment - maybe I can upgrade lower.

Do I need something that has both a lowpass (for the sub) filter and a highpass (for the bookshelves) filter. Can one crossover unit combine this, or do I need 2?

I'm looking at spending no more than $100.

Is this possible?

thanks for the help (in advance)

Sogood51...I did study the material on 1st order series X/O which Karls provided. (If you are there Karls, thanks again). Once you wade through all the greek alphabet it really doesn't say anything profound (IMHO of course).

Next thing I predict is a parallel/series three way crossover. Be the first on your block to own one:-)

There is also Outlaw Audio's ICBM. While primarily designed for bass management for multi-channel audio (SACD, DVD-A), it can also be used as a 2-channel crossover. It has continuously-variable crossovers from 40HZ-up, and either maintains stereo bass output or combines low-level signals into a mono LFE-out.

New it is only $249, and I think there are some used ones listed on A'gon for under $200.

Sumo had an old crossover that meets all of your criteria... Delilah

The X30 is very good,  although the ICBM is much better even if you only use the front two channels......I had both and I regret selling the ICBM.

Those paradigm x30 are handy and sound pretty good. At a point I had 2 of them. 

When they say mini they arent kidding. If you can find these used grab one, used in the neighborhood of $100 or less https://www.minidsp.com/products/minidsp-in-a-box/minidsp-2x4
