Axiom Home Page Forums General Discussion The Water Cooler LCD lights on a sub?

My Denon does have onscreen sub volume controls but I don't always feel like turning on the TV, changing to the appropriate input, going through the set-up menu, switching back to cable, turning off TV, etc...
Regardless the Denon will not adjust the range of frequencies for the sub below the factory presets of 80hz, 100hz(?), and 120hz(?). I generally don't like my sub playing up to 80hz when listening to music, preferring it to stay much lower. Therefore, when watching a movie, I must get off my butt and use the subs knobs to get the crossover out of the way - hence my question about some illuminated dials or something.
