- ABS basket reinforced with fiberglass. The basket has been engineered to obtain the maximum torsional rigidity (resistance to bending), but at the same time, offer the minimum resistance to the passage of air.
- Pressed paper cone (woofer) with waterproof treatment. It is widely recognized that cones made of paper offer the ideal marriage between of lightness, stiffness and the ability of the cone to dampen any unwanted vibration (read: distortion).
- High damping single wave rubber surround. The edge is much more stable during temperature changes than standard rubber.
- The 25 mm voice coil uses an aluminum support and a double layer winding technology of copper wire with an aluminum core.
- High grade ferrite magnet (woofer) and N35 neodymium magnet (tweeter) with significantly higher performance than "standard" magnets.
