The HEDD AMT

Beautiful, isn’t it? All the ingredients you need to build one of Klaus Heinz’ HEDD AMT (which by the way is not a ribbon tweeter)

The HEDD AMT

The diaphragm of the AMT consists of super-light and heat-resistant Capton material, which is laminated with thin Aluminum stripes that carry the audio-signal.

The HEDD AMT

Each diaphragm is hand-folded multiple times with a special folding tool - demanding work. We are lucky to have Tatsiana (and of course Saziye) with us, a professional watchmaker with all the skills and thoroughness you need to achieve the best possible results.

The HEDD AMT

Folding is done!

The HEDD AMT

Now the diaphragm has to be glued to its frame.

The HEDD AMT

A felt is used between magnet and diaphragm to create a distinctive volume that helps damping the rear sound of the diaphragm.

The HEDD AMT

Adding the front pole plate and the waveguide completes the unit. Shape and material of the waveguide optimise the directivity and allow for a lower crossover frequency for the tweeter, something very useful for an improved midrange reproduction in 2-way-monitors.

The HEDD AMT

To complete the unit, the parts are screwed together. Additionally a terminal for the lead wires is mounted. Then the AMTs are measured.

The HEDD AMT

And we are done! A new HEDD Air Motion Transformer is born.
