The SCS4 delivers complete phase coherence for exceptional clarity, transparency, and three-dimensional imaging.
Like its much more expensive siblings, the SCS4's crossover is a true first order acoustic type that provides the utmost in spatial and depth imaging performance as well as overall realism. This is the only type of crossover that provides complete accuracy of amplitude, phase, time, and energy, and therefore the only type that does not distort the musical waveform. Proper application of this gradual-transition type of crossover requires the use of more expensive drivers with wider frequency ranges than are required for use with common quick-transition crossovers but the benefits also include improved uniformity of the speaker's output in all directions.
The SCS4's crossover is meticulously engineered to achieve extreme tonal neutrality and is constructed with extensive use of polypropylene and custom polystyrene capacitors.

Why phase coherence? Loudspeaker crossover networks are needed to direct the incoming signal to the appropriate driver---woofer, midrange, or tweeter. To preserve the critical phase relationships of the sound recording's harmonics, all the drivers' diaphragms must move in and out in step with each other and the speaker's input signal. THIEL's phase-correct electrical crossover networks represent state-of-the-art engineering that greatly contributes to the exceptional sound reproduction provided by our entire line of award-winning loudspeakers. |
