I run the speaker wires for my bookshelf speakers through my sub. The crossover is set for 150Hz so the sub handles the lower bass. My question is: If I want to biwire my B&W bookshelfs can I just run the biwire from the sub to the bookshelfs or do I have to run the biwire between the amp and sub as well? Or is biwiring not a possibility for this kind of setup? :scratchhead: Regards, Russ
