CROSSOVER

Crossover is the heart and soul of a loudspeaker, so does the heart and soul of Sonner.

The philosophy of Sonner's crossover design is to integrate all drivers to work in coherent manner which will be comparable to the sound that comes from a single driver speaker.

Sonner has developed a proprietary crossover technology that is called Panoramic Crossover Technology (PCT).

This crossover is designed specifically to control each speaker driver's frequency response, impedance variation and phase behavior. Low or flat impedance variation is Sonner's key design element, which makes our speakers easy to be driven by different type of amplifiers. The crossover's electrical and acoustic phase is determined using computer modeling in conjunction with the cabinet time alignment angle structure.

To enhance our precision crossover design, Sonner uses the highest quality crossover components with the tightest tolerance values selected only for our crossover.

All crossover components are point-to-point connected without using the interference of a Printed Circuit Board in order to achieve the highest purity of recorded sound.
Once the final crossover is assembled, every single crossover is measured using a software. This software allows us to compare the measurement results to the theoretical crossover design. After passing this quality control review, the crossover is encapsulated/potted in an Epoxy compound. The purpose of potting crossover is to reduce microscopic vibration from crossover components and downstream speaker drivers.

Because your recording has Soul, Soundstage and Imaging, we select crossover components by specific type and material and use extensive qualitative listening sessions to achieve the final voicing and final design of Sonner's loudspeakers.
