In the history and evolution of audio, Air-Motion Transformer (AMT) audio speaker technology was an industry influencing breakthrough by Dr. Oskar Heil. His original speaker design took a conventional seven-inch cone type mid-range driver and reduced it in size into an accordion-folded down design resulting in a more compact, incredibly small speaker of only one and a half inches, offering point-source dispersion. The resulting low-mass diaphragm was then suspended within a dipole magnetic field concentrating an intense field around diaphragm. When an audio signal current passed through the aluminum strips, the ensuing bellows-like motion of the folded pleats moved air five times faster than with a conventional cone driver and as a result producing unsurpassed sound quality. Many loudspeaker manufacturers have adopted this technology in their products. In small compact applications, speakers are still large in size and require external drivers, not with the HAMT-1.
Introducing the world’s first stand-alone, comfort designed and driven, AMT tweeter headphone, the HAMT-1 by oBravo.
With a patented and unique comfortable over the ear design with spun aluminum and finished with maple deemed perhaps to be the most comfortable over-the-ear headphone, the HAMT-1 will see its first North American marketplace introduction at RMAF. Adding to the AMT technology, oBravo has added a separate Neodymium driver, creating a true and realistic soundstage in a headphone in a comfortable headphone.
The HAMT-1 was ranked 4th out of 100 reviewed headphones on the occasion of the Taiwan High-End Audio show held this past August and was highly regarded as the latest in headphone technology at the Munich High-End Show this past May. KirmussAudio of Denver, Colorado has been appointed the exclusive sales and customer support office for oBravo. Sold through exclusive oBravo Audio Dealers, Dealers welcome!
