INTRODUCTION
Thank you for choosing this PROEL product and for your trust in our brand, synonymous of professionalism,
accuracy, high quality and reliability. All our products are CE approved and designed for continuous use in
professional applications.
DESCRIPTION
S series is a range of compact and powerful sub-woofers designed to complement PROEL full-range passive or
active speakers. The variety of size, power and SPL offered by the four S models provides the perfect low
extension solution for any speaker model available in the PROEL range.
All the S models feature high-excursion woofers in a Hybrid Band Pass configuration (HBP). This innovative
design provides a higher efficiency compared to direct radiation sub-woofers and, in addition, guarantees a
much better coupling of the tuning ducts with the external air, reducing the distortion and the air turbulence,
for a more defined sound and deep and punchy lows.
The new CLASS D amplifier modules with SMPS (Switch Mode Power Supply) can generate a massive amount
of continuous power in a compact, lightweight and reliable package. All the modules include a STEREO pre-
amp section, 24dB/oct. crossover filters with selectable frequency and PHASE reverse switch.
The cabinets are built with 15 / 18mm plywood and finished with extra-durable polyurethane paint. They
feature two flush handles and four sturdy 75mm wheels for an easy transport (S15 and S18 only).
