While "High Class" is our trade mark (particularly popular in West Africa), these speakers are designed for high-intensity sound reinforcement. Similar models, like the High Class HC-215, typically offer: Configuration: Dual 15-inch low-frequency (LF) woofers paired with a high-frequency (HF) compression driver (the red component visible through the grille). Power Handling: These are usually high-wattage units, often ranging from 4000w (Program/Peak power).
