Can I bi-wire from my sub woofer?


I have an amp with two speaker outputs.
I have speaker cables running from amp to sub-woofer, then from sub-woofer to speakers.
The sub-woofer is powered (Monitor Audio ASW 110).
My speakers are bi-wireable.
Is there any point in bi-wiring from the sub-woofer to the speakers?
Or is bi-wiring only good from amp to speakers?

All help greatly appreciated.

First of all, if the sub-woofer is powered, you should probably run RCA cables from the preamp directly to the sub-woofer. I think you should get better performance out of the sub if you connect that way. Then, run the amplifier directly to the speakers. Is there any reason this won't work? (Forget the bi-wiring.)
Better set-up is to have speaker cable from amp to speakers. THen have another speaker cable going from amp to sub. The sub will not present any significant load for the amplifier as it is a powered sub. This will make for as little interaction between sub and speakers as possible using speaker level inputs.
