This crossover network consists of two main components: a 2nd order (12
db/octave) low-pass filter that limits the upper frequencies that the subwoofer
has to reproduce (shown above), and a high-pass filter that limits the lower
frequencies the satellite monitors have to reproduce (shown below). The
Subwoofer LPF cutoff frequency (#4) and Satellite HPF cutoff frequency (#5)
controls adjust frequencies of the low- and high-pass filters, respectively. Both
have a range of 50 to 180 Hz.
You will need to use your ears to determine the best settings for these filters.
The frequency markings shown next to each control knob may give you some
guidelines. 50Hz (or above) might be used as a setting for music production.
80Hz is the proposed setting for Dolby Digital playback, while 100Hz is the
proposed setting for THX.
