The Oskar AVT / Heil A.M.T. ® Aulos Bookshelf speaker
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,

| The Oskar AVT / Heil A.M.T. ® Subwoofer for Aulos Bookshelf speaker | ||
 | In place of a speaker stand you can improve the bass of the Aulos with the specially designed subwoofer. The Aulos is simply fitted on the top of it, and is then connected to with the two speaker wires. The best result was achieved with a down firing bass in a closed box and slightly compressed in a well calculatedcabinet . Internal we use the resonators as with all other models. measurements: WxDxH:210 x 275 x 565 mm Feet: 225 x 290 Weight app. 13.– Kg. |  |
