ESB 3.6K3 Tremila Series 3 Way Component Speaker System with Midrange and Tweeters

3-Way Speaker System 3.28 1.1"/28 mm Dome Tweeter

The tweeter uses a Torcon® 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 it provides a smooth, linear and very extended response.
The 28 mm voice coil has an aluminum support and very light copper-coated aluminum wire. The coil is ventilated and damped with iron-fluid oil.
The special SVS ventilation design provides two benefits: optimal cooling of the voice coil and avoiding compressing the air at the back of the dome.
The neodymium N42 magnet, a type of magnet with significantly higher performance than "standard" magnets, is optimized with computer simulations to get better efficiency and improve linearity.

3.5"/90 mm Cone Midrange

ABS basket reinforced with fiberglass. The basket has been engineered 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 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).
Twin symmetrical wave rubber surround. The Perbunan® rubber edge is much more stable with temperature changes than standard rubber.
The 20 mm voice coil uses an aluminum support with a double layer winding technology of copper wire with an aluminum core.
High grade ferrite magnet, a type of magnet with significantly higher performance than "standard" magnets.

6.5"/165 mm Mid-Woofer

ABS basket reinforced with fiberglass. The basket has been engineered 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 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 Perbunan® rubber edge is much more stable with temperature changes than standard rubber.
