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 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 50mm 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.

“Going up a size, to enter the ‘affordable high end’ loudspeaker market was without doubt a gamble for Acoustic Energy, which has of late focused on less expensive designs. On the face of it the new Corinium is basically an upscaled 520 floorstander, but look closer and you’ll see a host of improvements and refinements that ratchet up the performance dramatically. Artfully designed and beautifully constructed, the result is a very powerful but subtle performer that is highly musically enjoyable yet super-refined. A real class act, right now this is near-impossible to beat at the price.“

“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.” 

“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.”

“Despite the spatial representation and the multitude of instruments, we do not experience a confusing scene, but rather a high degree of order and realism.”

“With this pricing, Acoustic Energy puts their new Corinium speakers on a very interesting price point, and they will be a formidable competitor to the competition in this price class.”

“This is one seriously special-sounding loudspeaker.”

“There’s no banging, booming or thrumming from that big cabinet; instead, this speaker sounds as tight and together as the classic AE1 standmounter ever did.”

“Allied to the Corinium’s smooth treble, velvety midband, and grippy bass is the ability to reproduce a stereo soundstage with superlative accuracy. It images brilliantly”

“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.”
