Audaphon

Audaphon is a German brand that searches worldwide for loudspeaker drivers with the highest quality characteristics.

Audaphon drivers feature an excellent price / performance ratio.

Only high-grade materials are used to ensure solidity and best possible sound.

For the high frequency range Audaphon offers

high quality domes,
ribbon tweeter
and Air Motion Transformer

of which the latter can hardly be surpassed in terms of airiness and transparency.

To our building proposals with Audaphon drivers.

The cabinet volume calculations are executed considering an external resistance of 0.3 Ohm. We are using, if no other data is known or available, the information supplied by the manufacturer.

Please note: the frequency response doesn't say much about the cut-off frequency inside the cabinet! Therefore, we mostly give you 2 examples with dimensioning considerations and an indication, how low the loudspeaker will reproduce.
