Innovative HBP Design

All S models feature high-excursion woofers in a Hybrid Band Pass (HBP) configuration. This advanced design enhances efficiency compared to traditional direct-radiation sub-woofers while ensuring superior coupling of tuning ducts with external air. The result is reduced distortion and air turbulence, delivering more defined sound with deep, punchy lows that elevate every performance.

Advanced Amplifier Technology

Equipped with new CLASS D amplifier modules powered by SMPS (Switch Mode Power Supply), the S Series produces massive continuous power in a compact, lightweight, and highly reliable package. Each module features a stereo pre-amp section, 24dB/oct crossover filters with selectable frequency, and a phase-reverse switch — offering precision control for any audio setup.
