The KS AUDIO FIRTEC ® technology is based on a combined Bessel filter and Differential filter
process to yield superior results. This means the high frequency response is the result between the
low pass filter and the input signal. In consequence the result is an optimal addition between the
high and the low frequency cross over points. Instead of a phase shift as found in an analog cross-
over, in the KS AUDIO digital process, the time domain of the low pass signal is only considered,
and the rest of the process follows this.
Importantly, the geometrical offset between the drivers is compensated for and the resulting
output is sample accurate to the input in the time domain. To assure the best possible equalization
of the entire system the FIR filters work with the entire signal path not just the individual frequency
range: the critical cross-over between high and mid frequency drivers are precisely corrected.
