Powerful low frequencies, effortless depth
 

The Estelon Aurus subwoofer extends any audio system’s low-frequency performance with deep, controlled bass and refined impact. Featuring advanced driver technology and a 1200 W amplifier, it blends effortlessly with A Series speakers for a seamless, immersive experience. Its sculptural design adds sophistication to any space.

Design Philosophy

At Estelon, we design loudspeakers and subwoofers that form a synergy with their acoustic environment. Every element in a room shapes how we perceive music. The Aurus is designed to disappear into the space, leaving only powerful, emotionally engaging bass that integrates naturally with the system.


Cabinet Technology

The AURUS cabinet combines precision-milled plywood with a thermoformed, mineral-doped composite shell, creating an ultra-rigid, inert enclosure. Its unique structure suppresses resonance and houses a 346 mm long-excursion driver paired with a passive radiator for clean, distortion-free performance. The adhesive bonding the materials further improves damping and stability. The passive radiator enhances low-frequency extension and output, while eliminating port noise.


Driver and Amplification System

The AURUS integrates a 1200 W bridged Class-D amplifier, delivering tight, accurate bass reproduction even at high output levels.

Filter and Input Configuration

AURUS features dual input systems:
- Active Analog Line-Level Filter (XLR input)
- Passive High-Level Filter (speaker-level input)
- Four filter profiles are available, optimised for AURA and AURELIA speakers, selectable via rear-
  panel switches.
- Level control includes ±6 dB for active input and 0 or +3 dB for passive input.
- All filters are designed for ultra-low latency, ensuring perfect phase alignment with the main
  speakers.

Custom Finishing

Because of the highly sophisticated cabinet shape, all the processes in the finishing stage are hand-made with extreme care by highly experienced specialists using the best technology and procedures. Standard finish is white. Custom finishes are available upon request.
