Description

Priced and Sold For my part
Suspended in ferrofluid for controlled damping, an extremely light aluminium voice-coil drives the dome. Aluminium, as a result of its extremely low weight, allows a larger coil diameter and more windings at a lower mass as in comparison to conventional designs. The warmth produced by the voice coil is dissipated to the magnet system with the assistance of ferrofluid cooling liquid.
The precisely optimized dome geometry and the low mass of the inner moving parts make sure that a very transparent and detailed reproduction of all frequencies.

The Esotec MD 142 is housed in a compact self-contained enclosure with a vented pole piece and damped rear chamber. It includes an integrated protective grille, and requires no additional airspace for installation.

It thus would possibly easily be integrated into a variety of install applications and locations, including kickpanel, in-dash, in-door or rear deck mount placement. In tandem with the incredibly powerful Neodymium magnet, the sound reproduced by the MD 142 is smooth, detailed, dynamic and simply amazing.
