Monacor AIRMT-130 Air Motion Transformers



Air Motion Transformers
are a special type of tweeter systems which have been developed by the German physicist Oskar Heil during his research on the characteristics of the human ear. The main feature is a film-covered cone with a special folding which vibrates like an accordion when an audio signal is applied. This folding allows to accommodate a large cone area at a minimum of space. The AMTs feature a dynamic sound, an excellent transient response, a high efficiency and a low harmonic distortion.
There are 2 STL files available for the AIRMT-130 for 3D printed waveguides.

G&L Techiek is een volwaardig dealer van IMG Monacor & JTS.
Monacor-IMG is de laatste jaren in kwaliteit erg verbeterd en kan meekomen met de bekende merken , maar is prijstechnisch wel gunstig gebleven. Wij hebben zeer weinig uitval of rep. op dit merk gehad, en dat ook bij installatie's die al jaren continu draaien. G&L Techniek doet echter wel een bewuste kwaliteits keuze uit het hun leverings programma.
