Powerful Bass Performance

PROEL introduces the S Series — a premium range of compact yet powerful sub-woofers designed to complement PROEL full-range speakers. This versatile lineup delivers exceptional low-frequency extension, ensuring any speaker model in the PROEL range can achieve a deeper, more impactful sound at an unbeatable price point.

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.

Durable Road-Ready Build

Built with 15/18mm high-quality plywood and finished with an extra-durable polyurethane coating, these cabinets are designed for both performance and longevity. Featuring two flush handles and sturdy 75mm wheels (S15 and S18 models), transportation is smooth and easy — making them ideal for touring, venues, or fixed installations.
