An intensive study of the different woods has made it possible to achieve the acoustic details in the Bass-region and to match the game-partner Heil A.M.T. The Heil A.M.T. works from 1050 Hz to 23 kHz with its almost mass less membrane.
The positioning of the speaker is easy, since the phase correct dispersion has this large advantage over other speakers in the market. The Aulos Bookshelf has the advantage of an uncritical load-behaviour as well as a high efficiency.
The low Mass of the Heil A.M.T. drivers guarantees a balanced sound-picture also with rather low levels. The Heil A.M.T. moves the air 5 x faster than conventional electrostatic-, Magnetostat – or dynamic loudspeakers,
