operate in the current domain. Krell Current Mode provides
speed and bandwidth performance that is not possible with
less sophisticated voltage designs.

sections: the high-pass filter and the low-pass, or sub, filter.
The user fine-tunes each section by selecting the filter type

frequency, and level, to enhance low frequency reproduction.
