“The Corinium has the look and feel of a true high-end loudspeaker, with the musical involvement to match. Acoustic Energy has created something that can compete well beyond its price.” — Ed Selley
Position in the Range
Corinium is the reference benchmark for Acoustic Energy. The AE320.2, AE309.2, and AE300.2 carry its DNA into more accessible designs, but Corinium is the halo product — the purest expression of AE’s 35+ years of British loudspeaker innovation.

“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
David Price, Stereonet.UK, Nov ’23 –
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
