Instructions
3.69C 6×9 Convertible Speakers
FEA motor optimized
25 mm copper/aluminum voice coil
High temperature aluminum former
Large high grade ferrite magnet woofer
N42 neodymium magnet tweeter
Axial forced coil ventilation
Fiber reinforced paper cone woofer
Hi module silk dome tweeter
Oversized single wave rubber suspension
Poly cotton spider
Computer designed ABS frame
Motor metal part CNC machined
ABS basket reinforced with fiberglass. The baskest have been engineered in order to obtain the maximum in terms of torsional rigidity (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 are the best marriage 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 when the temperature changes than the classic rubber. The 25 mm voice coil uses an aluminum support and a winding with a double layer technology of copper wire with an aluminum core. High grade ferrite magnet (woofer), and N42 neodymium magnet (tweeter) with significantly higher performance than the classic “standard” ones.
