The KC92 features two 9-inch drivers, derived from our flagship Blade HiFi Speaker. Their hybrid structure, with a shallow, concave aluminium skin atop a paper cone, boasts a substantial motor system and a vented design in the voice coil. This design achieves linearity and vanishingly low distortion, ensuring every detail is uncovered regardless of volume.
