Gladen Aerospace 60 AMT Aero Ribbon high end tweeter

Aerospace high-end tweeter Air Motion Transformer

The AEROSPACE 60 AMT tweeter has a clear, dynamic - energetic sound, a very good impulse behavior and a high level of distortion.

The Air Motion Transformer (AMT) represents a speaker concept that does not require a classic voice coil. On a thin Kapton foil (12 - 25 µm thick) a specially designed conductor track made of thin aluminum (also only 12 - 25 µm thick) is worked out using complex etching processes, which has a meandering course. In order to achieve high manufacturing precision, the film is folded by hand using special tools.

In contrast to conventional tweeter domes, the folded AMT membrane in the speaker does not move back and forth to create the tones. The movement takes place in the folds, i.e. laterally, similar to bellows. This accelerates the air in the folds and exits at the front. An advantage of this technology is that the membrane area is larger than the visible area and therefore requires less space.

Coupled with the light weight of the membrane, this results in a detailed and dynamic reproduction.

All housing parts are CNC-manufactured, nickel-plated, powder-coated and then laser-engraved. The aluminum frame can be dismantled to enable an even more compact installation. The special copper cable with silicone jacket and braided protection is connected directly to the cone to avoid unnecessary transitions or materials in the signal path.
