Optimized to Go to Extreme Lengths for Exceptional Sound: Wharfedale AURA 1 Bookshelf Loudspeakers Feature Innovative Tweeter, Driver, and Crossover

To what lengths does the Aura 1 bookshelf loudspeaker go to ensure you experience playback marked by acoustic transparency, exceptional realism, bass depth, and across-the-board proficiency? Consider that every element of this two-way bass-reflex model is refined, analyzed, and optimized to convey audio with nearly inaudible distortion and seamless ease, and you’ll get a sense of how much this two-way bass-reflex model values high-end sound. 

Adorned with a proprietary five-inch glass fiber matrix-cone driver and AMT tweeter, the 27.5-pound Aura 1 is built like no other standmount. It starts with the AMT transducers, which offer exceptional clarity and transient response. Immersed in a magnetic field, its folded diaphragm design reproduces pressure waves without blurring effects caused by diaphragm mass. The result: High-frequency detail that enhances the harmonic overtones of voices and instruments.

Similarly unique, glass-fiber matrix diaphragms for the midrange cones —  each terminated by high-flexibility rubber surrounds for transient accuracy and efficiency — have voice coils immersed in high-flux magnetic fields and controlled by copper-clad pole pieces to minimize distortion. Aura  1 also boasts a crossover that ensures seamless integration between the drive units. Here, the bass and midrange/treble crossovers are laid out on separate PCBs to minimize electromagnetic interference.

Measuring 14.41 x 9.69 x 13.86 inches (HWD), Aura 1 looks fantastic courtesy of lacquered wood cabinets that deaden panel resonance below audibility and feature smooth curves that disperse sound without undesirable reflections. Concealed from view, a downward-facing port directs high-pressure airflow through a series of slot ports in the plinth to match it with the air pressure in your room, reducing turbulence and increasing efficiency. Two sets of binding posts welcome bi-amping or bi-wiring.

Backed by a five-year manufacturer warranty, and sold with removable grilles and two pairs of rubber feet, Aura 1 plays with pleasing speed, dynamics, insight, and smoothness. Please contact a Music Direct audio consultant at 312-433-0200 to learn more about this special design. 

Glass-Fiber Matrix Cones
To complement the AMT transducer, AURA loudspeakers utilize proprietary woven glass-fiber matrix diaphragms for the midrange and bass cones. These cones, terminated by high flexibility rubber surrounds, deliver transient accuracy and efficiency. The voice coils, immersed in high-flux magnetic fields, are controlled by copper-clad pole pieces to minimize distortion. Mounted on die-cast aluminum chassis, the low-distortion motor systems provide rigidity and precise transient response for exceptional audio performance.

AURA Crossover
The crossover is the heart of every loudspeaker, and Wharfedale's AURA series features a meticulously designed crossover that ensures seamless integration between drive units. By accurately dividing the frequency band and matching the acoustic performance of each driver, AURA loudspeakers achieve a blend that is acoustically seamless. The crossovers are tested and evaluated for their acoustic transparency, and the bass and midrange/treble crossovers are laid out on separate PCBs to minimize electromagnetic interference. 

Multi-Layer Lacquered Cabinet
AURA cabinets are engineered to optimize sound quality. Crafted with multiple layers of different woods, the cabinets reduce panel resonance below audibility, ensuring a clean audio output. The smooth curves of the cabinet help disperse sound without undesirable reflections, enhancing the overall listening experience. 

SLPP Reflex Design
Wharfedale's SLPP (Slot Loaded Profiled Port) bass reflex design, originating from a concept by Gilbert Briggs, provides enhanced bass performance in AURA loudspeakers. The downward-facing port directs high-pressure, high-velocity airflow through a series of slot ports in the plinth, matching it more efficiently with the low air pressure in the room. This design reduces turbulence and improves the bass reflex system's overall efficiency. Combined with the low resonance of the bass units, the SLPP system delivers powerful and articulate bass extension down to the 30Hz region, faithfully reproducing the true acoustic power of musical performances.
