Based in Almere, Netherlands, Alcons Audio has carved out a unique position in the pro-audio world by replacing traditional dome compression drivers with **patented high-output Pro-Ribbon Transducers**. The result is a line array that delivers audiophile studio-monitor fidelity at stadium sound pressure levels.
1. The Pro-Ribbon Transducer Advantage: Zero Power Compression
Standard compression drivers force high-frequency acoustic energy through a narrow phase plug and compression throat, causing harsh harmonic distortion and thermal power compression above 10 kHz. Alcons' patented **RBN series Pro-Ribbon drivers** produce a natural, isophasic cylindrical wavefront directly from the ribbon membrane with **up to 90% less total harmonic distortion (THD)** and razor-sharp transient response up to 20 kHz.
