Research at the highest level

The ESB 3000 speaker system was developed and assembled with a great commitment to the research of materials and engineering solutions of the highest level.

The baskets have been engineered in order to obtain the maximum in terms of torsional rigidity (bending). Pressed paper with waterproof treatment is the best marriage of lightness, stiffness, and the ability of the cone to dampen any unwanted vibration. All the woofers are equipped with a motor with a grade Y-35 Ferrite magnet, with significantly higher performance than the classic "standard" ones.

The tweeters use a silk-impregnated thin fabric dome diaphragm for a smooth sound, and oversized voice coils, ventilated and damped with iron-fluid oil.

They are supplied with accessories for flexible installation.

Treated paper cones:

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). The paper cone, widely known for its excellent sound attributes, is waterproof, thanks to a polymer developed exclusively by ESB. The treatment does not change the appearance and parameters of the speaker like the shiny polymers that add an appreciable amount of mass to the cone itself and significantly modify the sonic result.

The treatment protects the cone from water dripping (like inside a door panel), as well as accidental splashes on the front of the cone.

Basket and ventilation system: 

The ABS basket, reinforced with fiberglass, has 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 displaced by the cone from the rear face. This is clearly visible from the numerous stiffeners and ribs. The basket plays a fundamental role in aligning the coil in the magnetic circuit, its rigidity is crucial. A factor of no secondary importance is the damping of this component, often metal baskets tend to resonate, and this significantly alters the final sound result of the speaker. The material used, in addition to not being as sensitive to thermal changes, is non-flammable, and also non-resonant.

In addition, the ABS frame allows for a better clamping force-torque than typical pressed steel frames and ensures that the voice coil remains well centered within the magnetic field.
