Wharfedale AURA 4

The flagship tower from Wharfedale's latest series

Wharfedale's new AURA 4 sits at the very top of the company's new AURA lineup of speakers. Its design is inspired by even higher-end Elysian models. This floor-stander uses advanced driver and crossover designs to deliver outstanding sound quality and value. Use a pair as the front left and right speakers in your AURA home theater system, or as the focus of your two-channel music system.

A complement of advanced drivers

The AURA 4 uses a three-way driver design for a wide soundstage, accurate imaging, and lifelike sound.

Starting from the top, you'll find a high-performance AMT (Air Motion Transformer) tweeter dishing out the highs. This unique tweeter design uses a folded diaphragm to get a much larger tweeter in a smaller area. The tweeter's diaphragm is immersed in a powerful magnetic field to give it lightning-quick response times. It reproduces silky-smooth highs with minimal distortion and incredible detail.

Midrange frequencies are handled by a punchy 4" driver, while the low-end is dealt out by dual 6-1/2" woofers. These drivers use Wharfedale's unique woven glass-fiber matrix diaphragm. The material is both lightweight and stiff, giving the drivers lifelike attack and decay. The midrange and woofers are each seated in a die-cast aluminum chassis and feature a low-distortion motor structure.

Precision crossover networks

Great drivers need great crossovers to sound their best. Wharfedale spent hundreds of hours fine-tuning the crossover in the AURA 4s, using both advanced analysis and careful listening. As a result, these crossover networks ensure that the woofers, midrange, and tweeter each play exactly the frequencies they were designed for, while keeping the transition between the drivers seamless. The tweeter/midrange crossover circuit is laid out on its own board, separated from the woofers' crossover circuit. That helps to keep interference and crosstalk out of the equation.

A gorgeous and carefully designed cabinet

The AURA 4 is beautiful to look at, but behind that beauty lies a lot of purpose and forethought. Each cabinet is crafted with multiple layers of different woods which reduces troublesome panel resonances to near-silence. The lack of sharp angles helps disperse sound while eliminating baffle reflections.

Wharfedale's patented SLPP (Slot Loaded Profiled Port) enhances the bass output. The downward-firing ports direct airflow from the cabinets down through a series of slot ports in each speaker's plinth to equalize the air pressure in the room and inside the cabinet. What that means in plain terms is reduced turbulence (or "chuffing") and increased efficiency.
