Exakt eliminates the magnitude and phase distortion inherent in traditional crossover design. By splitting the signal digitally, Exakt eliminates distortion so that every last note is delivered perfectly to each drive unit. So what you hear is a more faithful reproduction of the music as it was recorded.
Loudspeakers use a crossover to split the analogue signal into the parts each drive unit can reproduce.
A typical crossover design
However, in the analogue world, it is impossible to implement this crossover design with absolute precision. This is due to the introduction of two types of distortion: magnitude and phase.
Due to manufacturing tolerances, every analogue component is slightly different. This means that every analogue crossover in every speaker performs differently. This leads to variance in the crossover point, resulting in certain frequencies being louder or quieter than intended. This difference from design to reality is magnitude distortion and it occurs in all analogue crossovers.
Passive crossovers suffer from the most significant variation in the crossover point. Small variations in each component add together, leading to a wide variation in performance.
Active crossovers improve the accuracy of the crossover as they operate at lower voltage and current levels, reducing the tolerances of the analogue components. This reduces the amount of magnitude error, but magnitude distortion still occurs.
Magnitude distortion occurs in all analogue crossovers.
Exakt's crossover splits the signal in the digital domain. This guarantees accuracy as there are no analogue components in the signal path, and therefore no variation between parts to distort the signal. In an Exakt system there is precisely 0 dB of magnitude distortion, guaranteeing that the crossover always performs just as the designer intended.
This crossover design is implemented perfectly by Exakt with zero variance
If you play a 'Concert A' on a piano and also on an oboe, both will play the same fundamental frequency of 440 Hz. What distinguishes these sounds is the different harmonics – the mixture of other frequencies above the fundamental. The more accurately a system reproduces the delicate mixture of fundamental and harmonics, the more realistic each instrument will sound.
Analogue crossovers distort the true signal by delaying the relative timings of the fundamental and harmonics of all the notes you hear. This leads to frequencies recombining slightly out of phase at your ear, blurring the true sound of each musical instrument.
In all analogue crossovers the high frequencies always lead the low frequencies — delivered to the drive unit and in turn to the listener’s ears at different times.
Exakt delays the higher frequencies so they line up with the lower frequencies. When the music is recombined at your ear, the fundamental of each note and its harmonics arrive perfectly in time, preserving the true character of each instrument.
Analogue crossovers introduce phase distortion
