Re: Setting up L12
Have you run the auto setup(Audyssey)? That may set the speakers to large(full), in which case you'd want to manually set the sub to "Yes" and select a crossover setting for the speakers(Start with 80hz). Looks like it only goes 40hz then 80hz, etc.? Don't leave it set to Full/Large though as you won't be taking advantage of the sub.
Hope this helps!
