Tweeter Ribbon tweeter Classic Air motion transformer Woofer Subwoofer

Audaphon

Audaphon drivers feature an excellent price / performance ratio.

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

Ribbon tweeters and magnetostats are superior to conventional dome tweeters since they have less moving mass. Ribbon tweeters and magnetostats should be on the same horizontal level as the ears of the listener.

They have a perfectly plane radiating surface thus showing a flat frequency response.

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.
