Engineered for the true audiophile, the AURA Indigo Component Speaker System blends refined design with advanced acoustic materials to deliver clean, detailed, and emotionally engaging sound. Designed under AURA’s Russian R&D heritage, Indigo embodies the perfect balance between clarity, durability, and musical accuracy — a true statement for both SQ (Sound Quality) and daily listening enthusiasts.

The Indigo series represents the essence of Russian acoustic craftsmanship, combining robust build quality, premium components, and competition-level tuning derived from AURA’s EMMA-winning experience.

Midwoofer Highlights

• Frame: Precision-formed stamped steel frame with black anti-resonance coating, minimizing unwanted vibrations and structural coloration.
• Cone: Lightweight yet rigid glass fiber cone ensures accurate midbass reproduction with reduced distortion.
• Surround: Butyl rubber (NBR) surround provides long-lasting elasticity and linear cone control.
• Voice Coil: High-temperature 1” (25.5mm) voice coil wound on a Kapton former ensures superior thermal stability under dynamic loads.
• Magnet System: Robust 13 Oz (368g) ferrite magnet guarantees deep, controlled bass response with precision.

Tweeter Highlights

• Design: Compact silk dome tweeter reproduces smooth and natural high frequencies with excellent dispersion.
• Magnet: High-performance Neodymium (N38SH) motor structure with ferrofluid cooling maintains stable performance even at elevated SPL levels.
• Voice Coil: 25.4mm CCAW (Copper-Clad Aluminium Wire) voice coil provides fast transient response and enhanced sensitivity.
• Housing: Durable ABS plastic body allows surface or angled mounting, ideal for flexible installations in any vehicle.

Technical Insight: Why Indigo Performs Exceptionally

The AURA Indigo 6.5” midwoofer has been precisely tuned to deliver superior tonal balance within real-world car acoustic environments.

• A Qts of 0.70 ensures a controlled, musical response in door panel applications, delivering a natural midbass transition.
• A Bl factor of 5.8 T·m combined with a ferrite magnet guarantees powerful motor control and dynamic energy transfer.
• The lightweight 14.2 g moving mass (Mms) enables quick transient handling — vocals, guitars, and percussions sound alive and uncolored.
• 4.5 mm of linear excursion (Xmax) ensures distortion-free performance at higher listening levels, preserving clarity and musical depth.
• The glass fiber cone and NBR surround combination suppress unwanted resonances, allowing pure and transparent sound.
