ESB 3.69C

Main Features

– 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.
– 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 (read: distortion).
– High damping single wave rubber surround. The edge is much more stable with temperature changes than standard rubber.
– The 25 mm voice coil uses an aluminum support with a double layer winding technology of copper wire with an aluminum core.
– The tweeter has a silk-impregnated, thin fabric dome diaphragm for a smooth sound, with an outer suspension covered with a high-loss damping material to eliminate edge vibration and resonance. The dome is of extremely low mass and is much less susceptible to mechanical deformation than other tweeters, yet provides a smooth, linear and very extended response.
– High grade ferrite magnet (woofer), and N42 neodymium magnet (tweeter) with significantly higher performance than “standard” magnets.
