Concentrated power and sophisticated control are the central features of the new AURUM active electronics. Both models are powered by high-performance Class D amplifiers for the subwoofer and midwoofer range. Musical analogue amplifiers are used for the tweeters.

The larger AURUM ALPHA achieves an impressive 700W@1%THD. The modules are controlled using a high-power digital signal processor (DSP). The DSP sets extremely precise requirements for each speaker chassis. To minimise the room influence, a full version of the multi-award-winning DIRAC® calibration system is included in the package. The performance is polished by analogue symmetrical/unsymmetrical inputs and an optical S/PDIF digital input.

Maximum performance from the smallest box – the new AURUM active model in short. To produce such great output from such a compact device requires a sophisticated overall design.

The basses play in a closed chamber: this concept is ideal for the cleanest impulses and a melodic, musical bass. It saves space but it needs a long-throw, low-distortion subwoofer and lots of power – no problem for the new AURUM active model. The full active loudspeaker with 350W and 700W guarantees unlimited dynamic.

To ensure the resulting heat for this enormous performance doesn‘t become a problem, the electronics are situated in a separate chamber with a flue-effect ensuring effective heat dissipation. This chamber alone requires as much space as a small tower speaker.

To create a slim front with good all-round emission, the woofers are placed on the side – a particular challenge for the midrange. These are isolated from each other and require a huge amount of power but still have very low distortion. The 15 cm and 18 cm mid range of the AURUM passive series pass this test with flying colours.

The best feature of the AURUM active model is undoubtedly its option to stream music from different sources. The simplest way: insert a USB stick with music files, select it in the app and enjoy listening immediately.

You can also connect your home network through the app in just a few clicks to play the entire music collection saved on a favourite network drive. If you like listening to the radio now and again, the AURUM active loudspeaker can also access hundreds of radio stations or podcasts through airable®. To cover the many streaming services, we have also integrated Tidal® initially due to its high-resolution data format, with vastly superior sound to standard compression.
