The fact that the Aurora series does not accept any compromises in the bass range can already be seen from the double bass configuration with generously dimensioned woofers of the two floorstanding speaker models. Uninhibited bass fanatics who need that certain something or audiophile movie buffs who consider subsonic frequencies to be essential, also fall back on the Aurora Sub 30 A. A 30 cm chassis, driven by a high-performance Class A / B power amplifier with a maximum of 250 watts and a depth that, despite its compact dimensions, extends far into the bass cellar, guarantees an impressive acoustic experience with music and film sound. The sturdy MDF housing is particularly stable and braced on the inside so that there are no disturbing resonances with the enormous bass force.
