Eton 7-318 Arcosia 7" Magnesium Composite Cone Woofer - Silver & Black
  • Dynamical Cone Geometry
  • Airflow Optimized Motor
  • Ventilated Phase Plug
  • Ventilated Back Plate
  • Also Available in Silver
The Arcosia drivers are engineered with some very unique and extraordinary features.  

The magnesium composite cone is perforated with holes in increasing diameter spiraling out from phase plug. The cone is then coated from the back, with the coating material protruding through the holes, creating pliant bumps on the front of the cone. This process was designed to dampen unwanted resonances in the lively magnesium cone. This unique method smoothes the frequency response without the use of a stiffer high damping surround, which can have the undesired effect of dulling the speakers sound.  

The ventilated phase plug helps cool the voice coil and eliminates distortion that can occur behind a traditional dust cap.   

The back plate has exhaust holes to help with voice coil ventilation. A spiral pattern is also milled into the back plate from the ventilation holes outward. This beautiful back plate yearns for a viewing window in the enclosure or open baffle design. These are stunning drivers!
