Description 1-inch (25 mm) silk dome decoupled tweeter with Anti-Diffraction WaveGuide and Tweeter Distortion Reduction 3.75-inch (95.3 mm) Hybrid Composition Conical Cone midrange driver with Long Displacement Surround technology 4-inch (101.6 mm) Hybrid Composition Conical Cone woofer with Long Displacement Surround technology Anti-Diffraction Waveguide (ADW): Provides improved off-axis response with more uniform high frequency extension. Hybrid Composition Conical Cone (HCCC): Provides the stiffness and strength of aluminum or titanium, with the transient response and smoothness of wood fibre. Tweeter Distortion Reduction (TDR): Provides lower distortion, greater high frequency extension and smoother high end. Long Displacement Surround (LDS): Provides cleaner, tighter, deeper bass. Aluminum centre-plug: Eliminates cone breakup for faster attack and increased vocal clarity. Additional voice-coil cooling reduces power compression
