FEATURES
- 24mm Soft Tetolon tweeter cooled by ferrofluid for a detailed and natural reproduction of the high frequencies.
- RHFC (Rotary High Frequency Contour) tweeter that can be perfectly aligned to ensure optimal reproduction in off-axis operation.
- Adjustable high frequency system for a perfect frequency response in every listening position.
- The design and geometry of the tweeter faceplate has been optimized using FEM (Finite Element Modeling) simulations for a linear frequency response, even in off-axis installations.
- The woofer/midrange driver has a 25mm voice coil mounted on an aluminum carrier, which ensures good thermal resilience and high excursion.
- 5″ x 7″ oval, single pressed SPP-M membrane (Pressed Paper-Mica) enhanced with mica powder for an excellent balance between weight and damping.
- High density ferrite magnet combined with low carbon pole plates for reduced distortion.
- Compact 4 spoke basket with a magnetic protection made of rubber which ensures good decoupling of vibrations of any kind.
- Elegant, heavy-duty speaker grille made of ABS plastic with metallic finish and a metal grille.
