Sub wiring - using RCAs

[Juzzie Wuzzie]

Both my Naim Uniti Lite and Primaluna preamp have stereo RCA outs for inclusion of a powered subwoofer. However, neither has the ability to divert the low end to the sub and the mid/high end to the speakers. As such, I'm stumped as to how one connects a subwoofer. Any ideas?

NB: more out of interests sake rather than I'm actually going to do it.

In exactly the same way as most people have their subwoofers setup - using only the low pass filter on the subwoofer to take over from the main speakers based on the natural in-room roll-off of the main speakers. It's the same basic principle, you just don't have the luxury (and benefits) of having an adjustable high pass filter - consider it 'fixed.'

With a REL sub, you would use spade connectors on the speaker output posts.
