Acoustic Energy Corinium Floorstanding Speakers
Corinium by Acoustic Energy is the latest addition to our award-winning line up of loudspeakers.
Following the culmination of a three-year project for our in-house design team, this brand-new, next-generation floor-standing model is set to establish further new standards in sound, design and value.
Using the AE520 as a benchmark and leaving no stone unturned, the team slowly chipped away at all areas of its design. The result is a more dynamic, live sounding and musically involving loudspeaker than we’ve ever created before. So, how did we achieve it? Starting with the same carbon fibre drivers used in the 500 Series that offer a good blend of mass, stiffness and damping, we knew they could go further.
A new cone design was specially developed with a low hysteresis motor system to provide the best efficiency and greatest possible performance... the second generation of carbon fibre drivers was born. The tweeter is also a new design. Having used carbon fibre in the 500 Series the team decided the moving mass of the tweeter should be reduced to offer the fastest possible high frequencies. So we started to search for a material lighter than carbon fibre and subsequently sourced a new soft dome encased in a synthetic polyester material called Tetoron.
This newly developed tweeter design has now proven to lower coloration, increase delicate high-speed transients and reproduce the very finest detail and refinement. Internally we’ve used audiophile grade cable featuring a patented arrangement of conductors for clear improvements in musical detail and dynamic expression. The crossover uses large air core conductors, metal oxide resisters and polypropylene film capacitors that have all been carefully evaluated for matching with the drive units. All of these ground breaking new developments are housed in a beautifully curved and exquisitely finished cabinet.
These Hybrid Resonance Suppression Composite (RSC) cabinets have a minimum thickness of 22mm and vary up to 45mm for optimal performance. The 4 degree tilt improves the time alignment whilst the 6mm ultra rigid aluminium front baffle firmly houses the drivers.
And finally, why the name? Cirencester in the beautiful Cotswolds, our hometown for more than 25 years, was an important outpost in Roman Britain. In fact it was the most important town outside of London. They named it Corinium and we’re proud to name our most significant and impressive loudspeaker to-date after our town.
Tweeter
Building on the success of our carbon fibre dome on the 500 series, we identified the need to use an even lighter dome for the Corinium to maximise the transient response of the system. So, we searched for a material lighter than carbon fibre and subsequently sourced a new soft dome ‘Pearl’ material. This newly developed tweeter design has now proven to lower coloration, increase delicate high- speed transients and reproduce the very finest detail and refinement.
Mid and Bass Drivers
At the heart of the Corinium is the midrange drive unit. Covering 5 octaves it’s the key element which produces most of the sound from the loudspeaker system. The new carbon fibre cone and surround helps provide specific tonal qualities we were targeting for this speaker... offering the most natural sound and realistic musical performance. The extra width of the Corinium cabinet allowed us to house a slightly larger bass driver. We went back to basics to develop a brand-new bass alignment that combines weight, speed and slam to produce a natural, realistic sound from what’s still a fairly compact loudspeaker system. In conjunction, we developed a brand new 165mm bass driver to produce a big, powerful, controlled and natural bass sound.
Crossover
Optimised for best transient performance, our 3-way crossover blends the power output of each transducer to provide a rich, tonally balanced sound. High quality components are used throughout including air core inductors, metalized polypropylene film capacitors and metal oxide resistors. The crossover is connected to the drive units using audiophile grade internal wiring which features a patented arrangement of conductors to give the best possible musical detail and dynamic expression.
Cabinet
All these ground-breaking new drive unit and crossover developments are housed in a beautifully curved, exquisitely finished inert enclosure. The hybrid ‘Resonance Suppression Composite’ (RSC) cabinets have a minimum thickness of 22mm and vary up to 45mm for optimal performance. The 4° tilt improves the time alignment of sound to listener, whilst the 6mm ultra rigid aluminium front baffle firmly houses the drivers and isolates any cabinet resonances from the listening environment.
