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....

Frankly, if you use the Onkyo, you will still be faced with the problem that you lack proper crossovers. Y-connectors are a non-issue; use 'em if you need 'em.

None that I know of. Either you work at speaker level (where one set of amps drives all) or at preamp level (where a separate amp is needed for each output of the crossover).

Then you are not using any crossover, at all, on the Legacy monitors and I don't know what those "subs" have as crossovers for themselves. I suspect none. Do you know?

Get a decent powered sub with a built-in amp and crossover.

First, you need a real crossover for both the main speakers and the sub. Second, you need a level control for the sub. Third, you need something to power the sub.

It appears that you are very "price sensitive" so I must tell you that I know of no mainstream affordable products that will suit your needs, new or used.

What will work and is inexpensive is a plate amp from sources like:

Rabco-

Have you looked at these products at all? Many provide for an RCA input, a high-passed RCA output for the main channel speaker amp and, of course, internal routing to the subwoofer of the low-passed signals. No Y-connector is needed.
