Powerful Low-End Performance

PROEL introduces the S Series, a new range of compact yet powerful sub-woofers designed to perfectly complement PROEL full-range speakers. Available in four active models with varying size, power, and SPL, the S Series delivers unmatched low-frequency extension at an unbeatable price point, making it an ideal solution for any speaker system in the PROEL range.

Innovative HBP Design

All S models feature high-excursion woofers in a Hybrid Band Pass (HBP) configuration. This advanced design offers higher efficiency compared to direct-radiation sub-woofers while improving air coupling in the tuning ducts. The result: reduced distortion, minimized air turbulence, and a cleaner, punchier, and more defined low-frequency response.

Reliable Class D Amplification

Equipped with next-generation CLASS D amplifier modules and SMPS (Switch Mode Power Supply), the S Series generates impressive continuous power in a compact, lightweight, and dependable package. Each module includes a STEREO pre-amp section, 24dB/oct. crossover filters with selectable frequency, and a PHASE reverse switch for maximum control and adaptability.

Durable Road-Ready Construction

Crafted from 15/18mm plywood and coated with an extra-durable polyurethane finish, the S Series cabinets are built for professional use. Designed for mobility, they feature two flush handles and four robust 75mm wheels (on S15 and S18 models) ensuring easy transport without compromising reliability or performance.

Low-frequency sound is crucial for creating a full, immersive audio experience, but many subwoofers struggle to maintain clarity and power at high volumes. The Proel S18 A addresses this challenge by combining a hybrid band pass system with an 18-inch woofer featuring a 4-inch voice coil.

This integration simplifies setup and reduces the equipment footprint, allowing you to focus on your sound rather than complicated wiring. The frequency response range of 36 Hz to 140 Hz covers the essential sub-bass spectrum, ensuring that the deepest tones are reproduced accurately. Additionally, the onboard controls for volume, ground lift, crossover frequency, and phase allow precise tuning to match your main speakers and room acoustics, giving you full control over your sound environment.

The Proel S18 A is designed with practical considerations that matter in professional settings. Its cabinet is constructed from 15/18 mm plywood with a durable black anti-scratch paint finish, providing both strength and longevity. The 1.5 mm metal grille protects the woofer from physical damage while maintaining sound transparency. Portability is facilitated by two sturdy handles and four 75 mm wheels, making transport and stage positioning easy despite its substantial 36 kg (79.4 lb) weight. Additionally, the inclusion of a pole socket enables seamless integration with speaker stands for versatile system configurations.

Connectivity options are comprehensive and professional-grade. The subwoofer features two Neutrik combo inputs, two Neutrik XLR-M outputs, and two link outputs, ensuring compatibility with a wide range of audio equipment and simplifying system expansion. The power supply supports both 230 VAC and 120 VAC at 50/60 Hz, making this subwoofer suitable for use in diverse geographic regions without the need for additional converters.
