With Aurora, you listen in YOUR way.
The passive radiators work like Helmholz resonators. In order to operate correctly in audible range they cover
25Hz - 60Hz only, they must be tuned to a very low frequency - approx. 18Hz - as the resonance causes a cut in
output at the self-resonance frequency. Passive radiators often feature extra weights to tune them.
For our custom passive radiators, we selected a suitably heave material to achieve the correct resonance
frequency. As an extra benet, the carbon/ferrite alloy diaphragm, together with the foam layer, is very well
dampened. It does not allow the sound from the back of the wideband drivers to escape through the passive
radiator and colour the sound.
The carbon/ferrite alloy delivers the required acoustic parameters in a thinner device than other materials
would. It is simply the 'appropriate tech' for our requirements.
TrueBass is another proprietary sound-tuning technology that operates
strictly in the analogue domain. The depth and quality of bass supplied by
all-in-one lifestyle systems often leaves a lot to be desired. The TrueBass
system, incorporating the two downward-ring bass radiators, ensures that
the Aurora delivers genuine bass with realistic depth and denition. Dual-
level depth control means you can adjust the bass response according to
taste – down to a deeply impressive 27Hz – so that everything from timpani,
to a bass guitar, to an electronic bassline is conveyed with power and poise.
