MD 142 Soft Dome Midrange 


The Esotec MD 142 75mm (3-inch) diameter soft dome midrange features a large diameter aluminum voice coil with a centered magnet housed in a relatively compact and shallow enclosure. 

Suspended in ferrofluid for controlled damping, an extremely light aluminium voice-coil drives the dome. Aluminium, due to its extremely low weight, allows a larger coil diameter and more windings at a lower mass as compared to conventional designs. The heat produced by the voice coil is dissipated to the magnet system with the help of ferrofluid cooling liquid.
The precisely optimized dome geometry and the low mass of the internal moving parts ensure 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 may easily be integrated into a wide range 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.
