For years, Crystal Cable loudspeakers like the Minissimo Forte explored how cabinet geometry, resonance control, and passive-active crossover technology could redefine what a compact speaker can achieve. At the same time, Siltechβs Symphony pushed engineering even further.
Those technologies did not disappear. They evolved.
Today, they live onβrefined, expanded, and elevatedβin the Sphinx Audio Engineering Element Series.
The Element 3 and Element 5 draw their inspiration from that foundation:
- Transmission-line bass alignment
- Passive/Active Crossover (PAC) technology
- Extremely high efficiency and benign impedance
- Radical cabinet engineering to eliminate resonance
- Hybrid-powered low-frequency control
What began as innovation within Crystal Cable and Siltech has become a dedicated loudspeaker platform under Sphinx Audio Engineering.
This is not a departure. It is the next chapter.
