Fiberglass-Reinforced ABS Basket: ABS basket reinforced with fiberglass. The basket has been engineered in order to obtain the maximum in terms of torsional rigidity (resistance to bending), but at the same time, offers the minimum resistance to air passage.
Waterproof Pressed Paper Cone (Woofer): Pressed paper cone (woofer) with waterproof treatment. It is widely recognized that cones made of paper are the ideal marriage between lightness, stiffness and the ability of the cone to dampen any unwanted vibration.
High-Damping Rubber Surround: High damping single wave rubber surround. The edge is much more stable with temperature changes than standard rubber.
25 mm Aluminum-Core Voice Coil: The 25 mm voice coil uses an aluminum support with a double layer winding technology of copper wire with an aluminum core.
High-Performance Ferrite & N42 Neodymium Magnets: High grade ferrite magnet (woofer), and N42 neodymium magnet (tweeter) with significantly higher performance than "standard" magnets.
