crossover newb with passive subwoofer questions

I am considering purchasing a stand alone crossover for my system.
My system is comprised of the following, source to speakers:
MacMini to DAC to tube line preamp to tube amplifier to *passive* subwoofers (one per channel) with monitor satellites wired off their respective channel subwoofer.
The crossover devices that I've seen all seem to have RCA outputs (rather than speaker outs) which would imply to me that that the subwoofer and satellites would need their own amplifier.
Is there a device, or way to avoid the need for another amplifier,using a crossover "seperate" with my passive subwoofer/satellite setup? I'm assuming that such an animal would allow for wiring the speakers for each channel in more of a parallel arrangement, as opposed to a series arrangement as I have them now....

This can be done with a capacitor feeding the monitors and an inductor on the subwoofer feed.Any idea of what frequency you would use for this crossover?
Do the "passive" subs have a level-control? And do you know the impedance of the sub and monitors?

I've used the Parts-Express plate-amps and they are a reasonably priced fix.They are mono units.Since you are using two subs-two are required.
Onkyo for subs:You will need a crossover.Maybe a Dahlquist LP-1 or the NHT X-1.The LP-1 is passive (capacitor) on top and active on the bottom.If you have two outputs on your pre,you might run the monitors full-range and use the LP-1s' bottom (variable freq/gain) to control/balance the subs.This will allow you to adjust the subs and not introduce more circuitry into the monitors.
