Wharfedale Aura Series
Aura 4
Three-way floorstander. Elysian performance.
The Aura 4 is a 3-way floorstander that inherits its AMT tweeter, glass fibre matrix cones, and SLPP bass loading directly from the Elysian series. With twin 6.5-inch woofers delivering bass extension to 26 Hz at −6 dB, a dedicated 4-inch midrange, and separated crossover PCBs to minimise electromagnetic interference, it offers Elysian-grade performance in a sleek, modern enclosure at less than half the price.

Key Features
AMT Tweeter
27×90 mm Air Motion Transformer inherited from the Elysian series — folded diaphragm immersed in a powerful magnetic field for ultra-low distortion.
4″ Glass Fibre Midrange
Dedicated woven glass fibre matrix midrange with copper-clad pole piece and die-cast aluminium chassis for transparent, detailed vocals.
Twin 6.5″ Glass Fibre Woofers
Dual long-throw bass drivers with high-flexibility rubber surrounds extend to 26 Hz at −6 dB with exceptional control.
Separated Crossover PCBs
Bass and midrange/treble crossover networks laid out on separate boards to minimise electromagnetic interference and lower noise floor.
Technologies Inside
AMT Tweeter
Air Motion Transformer precision.
Invented by physicist Dr. Oskar Heil, the Air Motion Transformer uses a folded, pleated diaphragm immersed in a powerful magnetic field to squeeze air laterally — like the bellows of an accordion — moving air four times faster than the diaphragm itself. The result is vanishingly low distortion, exceptional transient speed, and an effortless, open high-frequency response that conventional dome tweeters cannot match. Used across the Elysian, Aura, and EVO 5 ranges in sizes from 27×90 mm to 90 mm.
Glass Fibre Matrix Cone
The perfect bass and midrange diaphragm.
Wharfedale's woven glass fibre matrix cone offers an ideal combination of low mass and high stiffness, with a high-plasticity coating that provides damping to suppress high-frequency resonance. Unlike paper or polymer cones, the woven structure breaks up resonances at a microscopic level, resulting in a fast, detailed midrange free from colouration. Used in Elysian and Aura series drivers, terminated by high-flexibility rubber surrounds for transient accuracy and mounted on die-cast aluminium chassis.
SLPP Bass Loading
Slot-Loaded Profiled Port.
Wharfedale's Slot-Loaded Profiled Port directs high-pressure, high-velocity airflow through a series of precisely shaped slot ports in the speaker's plinth, rather than using a conventional round port. This reduces turbulence, eliminates port noise, and improves overall efficiency — delivering deeper, better-controlled bass from a given cabinet volume with improved dynamic performance at high listening levels. The SLPP system features across the Elysian, Aura, and EVO 5 ranges.
Sandwich Cabinet Construction
Resonance killed at the source.
Wharfedale's multi-layer cabinet construction bonds layers of different wood products together with high-damping adhesive — typically 6 mm MDF outer walls bonded to 12 mm high-density particle board inner walls. This sandwich structure shifts panel resonances below audibility and prevents energy storage that colours the sound. The Elysian and Aura series add precision-shaped internal bracing and curved cabinet walls to further reduce standing waves and diffract sound evenly.
