AURUS
Estelon AURUS extends any system’s low-frequency capability, delivering deeper, more articulate bass with exceptional precision and micro-dynamic detail. Employing advanced driver technology and a 1,200 W power amplifier, the AURUS integrates seamlessly with the rest of the A Series, creating an immersive, full-bodied low-frequency foundation; its cabinet design further refines spatial clarity.
At Estelon, we design loudspeakers and subwoofers to work synergistically with the listening environment. Every element in the room contributes to the perceived sound, and our designs take that interaction into account.
The AURUS design philosophy is to become part of the room—preserving controlled authority while allowing effortless, natural low-frequency integration with the system.
The AURUS enclosure employs precision-machined panels and a carefully selected composite shell to deliver an exceptionally stiff and inert cabinet with restrained coloration.
A tuned internal structure minimizes panel resonances and incorporates a 346 mm long-throw driver together with a dedicated reaction mass assembly, producing deep, uncolored bass with exceptional transient integrity.
Materials and construction further increase mechanical damping and stability. The reaction mass assembly raises the driver’s low-frequency extension and control while effectively suppressing unwanted resonances.
AURUS integrates a 1,200 W Class D amplifier and an optimized crossover network so it can supply controlled, authoritative bass even at high output levels, ensuring accurate, unstrained low-frequency reproduction.
Filtering and input configuration
AURUS offers flexible input options:
Active balanced line-level input (XLR)
Passive high-level input (speaker-level)
Four selectable filter presets are provided, optimized specifically for the AURA and AURELLE loudspeakers. Presets can be chosen via the rear-panel selector.
Level control includes ±6 dB on the active input and 0 dB or +3 dB on the passive input.
All filters are designed with ultra-low group delay to ensure precise phase alignment with the main speakers.
