sub-woofer/speaker wiring

i have a similar(sic) question to ubee67.

i have a Hafler DH200 amp, Bryston1B-MC preamp. I am running infinity 6Kappa speakers with infinity BU-1 subwoofers (pair). My current wiring is speaker out of the hafler to the sub then the speakers. The bu-1 i rolloff at 60 hz. 
Ok... here is the rub. The Bryston has two sets of outputs to feed one or two amplifiers (different rooms or...). But, between the Bryston and the Hafler, my signal path goes through aSoundcraftsman eq and an dbx 3 range expander. what I want to do is connect a cable from the 2nd amp output of the bryston to the subs. This will give me better gain control over both speakers. BUT i will lose some control over signal enhancement on the sub as i will remove the EQ/range expander from the signal path for low   frequencies.
Now i know there are those 'straight-wire with gain' folks who will pooh-pooh my system. Your comments have no weight with me for this discussion. But, i am interested in what others suggest on this conundrum.

thanks
