Examples of common features of the Balanced Drive members:

• Balanced Drive with perfectly symmetrical Bxl curve
• Rigid die cast alu chassis with extensive venting for lower air flow speed reducing audible distortion
• Vented voice coil former for reduced distortion and compression
• Vented center pole with dual flares for reduced noise level at large cone excursions
• Heavy-duty black fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
• Built-in alu field-stabilizing ring for reduced distortion at high levels
• Low-loss suspension (high Qm) for better reproduction of details and dynamics
• Black motor parts for better heat transfer to the surrounding air
• Conex spider for better durability under extreme conditions
