Description
Tweeter
Building on the success of our carbon fiber dome on the 500 series, we identified the need to use an even lighter dome for the Corinium to maximize the transient response of the system. So, we searched for a material lighter than carbon fiber and subsequently sourced a new soft dome 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 fiber 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 140mm bass driver to produce a big, powerful, controlled and natural bass sound.
Crossover
Optimized 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 50mm for optimal performance. The 4° tilt improves the time alignment of sound to listener, whilst the 6mm ultra rigid aluminum front baffle firmly houses the drivers and isolates any cabinet resonances from the listening environment.

“Acoustic Energy has let itself off the leash, so to speak, and finally done an expensive loudspeaker. The result is superb; it might not be cheap, but it certainly delivers more than one has a right to expect at the price. Indeed, it is closer to big floor standers from flashier names costing five-figure sums. Catch it if you can.” Nick Tate, Hi Fi Choice Magazine, March 2024

“I got some exhilarating results with these speakers, they consistently managed to dig deep into each piece played and brought out the power, the emotion and the scale of each, so when Shakti (the acoustic Mahavishnu Orchestra) play India it’s hard not to get swept away by the sheer beauty of the sound. By concentrating on building the most inert cabinet that they can and aligning the drivers and crossover with so much attention to detail, Mat Spandl and the team at Acoustic Energy have come up with a winner in the Corinium.” Jason Kennedy, EAR Magazine March 2024

This superb new loudspeaker is not only Acoustic Energy’s finest-ever design, in my view, but also one of the best mid-price bargains on the market right now. The Corinium costs a lot of money compared to the company’s cheaper products but is far superior – so the law of diminishing returns certainly does not apply in this case. It’s an excellent all-rounder with few apparent vices and delivers a subtle but powerful and musically enjoyable sound that many will relish. Its classy carbon fibre drive units and highly inert cabinet make for a slightly less ‘well-lit’ sound than is normal – there’s never so much as a hint of harshness or roughness here. Yet, just as with its cheaper siblings in the range, this speaker can rock out with the best of them – so you would never, ever call it dull. David Price, Stereonet.UK, Nov ’23

Acoustic Energy has introduced a beautifully finished floorstander with its new Corinium speakers. The limited edition in British Racing Green metallic in combination with the black front, base and drivers visually leaves us with a stately impression. With this Corinium, the manufacturer has attempted to develop a more dynamic, lively and musically engaging system than anything they have created before. An attempt has been made to create new standards in the areas of sound quality, design and price-performance ratio. Let us already reveal that we believe that the manufacturer has succeeded in its aim here with distinction. Harro Tillema, HiFil.nl Magazine, Jan 2024
