Electronic cross-over on pre-amp out, to split signal to subwoofer and bookshelf speakers

I have a 50 W amp for 86 dB bookshelf speakers.

I really want to keep both amp and speakers.

My idea is to have an electronic crossover on preamp out, split the signal say at 80 Hz - Send the lower electronic cross over out to a subwoofer.  Send the high crossover out to my existing 50 W power amps.

This would extend speaker frequency range to subwoofer capability - say 25 Hz, reduce the power amp load and allow to play the bookshelf speakers a bit louder,/ have more headroom.

I am sure others have already done.  What cross over did you use?  Was it successful?

"If you were just looking to add more deep bass to you system, then go with something like what REL offers that lets your existing loudspeaker run full range."

I agree , I run my Studio Electric M4 full range with my REL's crossover set low and it integrates perfectly.   

If i were to go with an external X over it would be one of high quality so as not to mess up the high pass to the main speaker.   

If you like to crank it up and have small mains it's probably not a bad idea to implement a crossover but I would spend some $$$ on a JL, Marchand or SPL .  You want one where you can adj the high pass and low pass freq and slope.
