Concept 50
Floorstanding Speaker

A sonic step-up from the Concept 30, this elegant floorstander takes everything great about its standmount brother but delivers more powerful audio, a deeper soundstage and increased bass extension through its leading-edge, low resonance cabinet.

Concept 30
Standmount Speaker

Taking acoustic technology and design cues from the flagship Concept 300, while also introducing new audio innovations, the Concept 30 standmount delivers truly high-end home audio performance.

Concept 90
Centre Speaker

At the heart of a Concept 5.1 home cinema set-up, the Concept 90 is our most high-performance centre channel speaker yet. Able to deliver astonishingly dynamic and ultra-clear dialogue, this speaker is the star of the Concept home cinema range.

Star role in home cinema

A centre channel speaker in a 5.1 home cinema set-up plays a crucial role to convey a realistic surround sound experience. More than just supporting the front left and right channel speakers, a centre channel anchors the dialogue while also seamlessly being part of the whole soundstage. As a key player in the Concept 5.1 package, the Concept 90 is our most advanced and striking centre channel speaker, featuring many anti-resonance technologies that appear in its Concept stablemates to deliver a focused but captivating cinema sound.

No artificial colouring

Suited to larger spaces, the Concept 50 offers a truly high-end home audio performance without the high-end price tag. Every element of acoustic innovation featured in the Concept 50 is geared towards designing the quietest cabinet possible. Unaffected by internal and external resonances, these speakers deliver focused stereo imaging, accurate audio and an extended holographic soundstage to emulate a live performance in the home.

Boasting a higher sensitivity for enhanced dynamics, this floorstander thrills with its sheer musicality and uncannily realistic soundstage.

Controlled power

Designed as an integral part of the mechanical structure of the cabinet, both the 5-inch mid/bass and 1.0-inch tweeter drivers are new, ground-up designs specifically for the Concept 30, 50 and 90 loudspeakers. The drive units are fixed to a remarkably stiff 3mm aluminium baffle plate before it is fitted to the cabinet - this gives the correct acoustic seal, dampening vibrations and minimising structural coupling.

Elsewhere, the tweeter is hermetically sealed and mechanically isolated (floating) from the baffle, which means lower distortion and a lower crossover point for seamless integration through the crossover region. At 30.5mm, the larger mid/bass driver voice coil increases motor strength resulting in a 50% increase in power handling over a comparable driver with 25.4 mm voice coil.

Lastly, the crossover itself is mounted to the isolation base, keeping it free of sound-effecting vibrations and away from the electro-magnetic influence of the drivers themselves.

HPE™ (Helmholtz Pressure Equalizer™) technology

The very nature of the Concept 50 tower design can introduce undesirable standing waves within the cabinet. By employing an HPE™ (Helmholtz Pressure Equalizer™) tube design, first launched in the Concept 500, pressure is converted to velocity to eliminate these performance-effecting vibrations and to help deliver the ideal frequency response.

Elegant design

Boasting the same sophisticated design lines and stunning, premium high gloss finish of the top-of-the-range 300 and 500 models, the new range retains the signature aluminium front baffle plate that made the original Concept speakers so iconic. The Concept 50 arrives in three striking lacquers: black, silver and white.

Gelcore™ technology

Introduced in the original Concept speaker, the Gelcore™ cabinet construction is designed to minimise high-frequency noise. A unique design comprised of a non-setting gel sandwiched between two individual layers, this specially developed adhesive dissipates high-frequency vibrations, generated by the moving drivers, into heat to maintain a focused audio performance.

Isolation suspension system

A variation on the hugely effective ‘isolation base’ principle first seen on Concept 300 means the Concept 50 have a suspension system in the form of a sprung baseplate. Two plates are separated by suspension ‘spheres’ that effectively isolates the cabinet from interference from external vibrations, providing tighter stereo imaging, while also bringing greater depth.

P2P™ (Point to Point™) technology

To keep the cabinet as rigid as possible, P2P™ (Point to Point™) internal bracing is employed. First introduced in the Concept 500, reinforcement is fitted to interior areas of the cabinet susceptible to low-end frequency reverberations.

Using Finite Element Analysis and laser interferometry to examine the performance of the cabinet down to a microscopic level, P2P™ bracing has been applied to the speaker cabinet.

Implemented this state-of-the-art technology, Q Acoustics have been able to identify and apply bracing to only the precise points of the cabinet that require additional support and unwanted energy is dissipated rather than transferred throughout the cabinet.

Bi-Wire Terminals

All models in the Concept series features Bi-Wire terminals on the rear of the cabinet. This means, using a compatible speaker cable, two pair of cables can be run from your power source (amplifer) to the speaker. One set of cables carries the high frequency signals, while the second pair transfers the mid/low frequencies.

The advantage of separating these frequencies through bi-wiring are two-fold: Intermodulation distortion caused by interactions between the high and low frequencies traveling down the cable can be minimised, with the result being noticeable improvement in the clarity of the mid-range.
