Q Acoustics Concept 500

Introducing the Concept series

Concept is our range-topping series of loudspeakers, consisting of Concept 30 and Concept 300 standmount models, Concept 50 and Concept 500 floorstanders, Concept 90 centre channel and Concept 50 5.1 home cinema package. Each one delivers pure audio excellence.

Our applied technology

Concept is the embodiment of all the technological advances we’ve made since we began, going beyond anything we’ve accomplished before. We truly believe these beautiful speakers deliver a performance never previously heard at these price points.

Oh so quiet

Our aim with the Concept series was to design the ‘quietest’ cabinet possible. From the pioneering Gelcore cabinet construction, through to the Isolation Suspension System, these technologies deliver close to a resonance-free speaker design, as possible.

Style along with substance

Exceptional engineering inside the cabinet is matched by stunning design. The premium finishes – white, black or silver lacquers, with dual gloss and Italian wood veneer also available for the 300 and 500 models - fits perfectly into any listening environment.

Gelcore cabinet technology

First introduced in our original Concept loudspeaker, the Gelcore cabinet construction is designed to minimise high-frequency noise. A unique design consisting of a non-setting gel sandwiched between two individual layers, our specially developed adhesive converts the high-frequency vibrations generated by driver movement into heat, allowing for a focused and uncoloured audio performance.

Isolation Suspension System

A refinement of the hugely effective ‘isolation base’ principle first fitted to Concept 300, the Concept 50 has an isolation suspension system in the form of a sprung baseplate. Two plates are separated by suspension ‘spheres’ that effectively isolate the cabinet from interference caused by external vibrations. The result is tighter stereo imaging and greater low-frequency extension.

Controlled driver power

Specially developed, ground-up driver designs include a hermitically sealed and decoupled tweeter enclosure to shield from internal resonances from the mid/bass driver and reduce distortion, a driver assembly baffle-mounted design to dampen vibrations, while a larger mid/bass driver voice coil increases motor strength, resulting in a 50% increase in power handling.

P2P (Point to Point) bracing

Q Acoustics P2P (Point to Point) bracing technology is used throughout the Concept loudspeaker range - it supports the parts of the cabinet that need to be stiffened, making the elegant enclosures exceptionally rigid. This improves the focus of the stereo image, and gives the soundstage more accuracy than ever before.  

HPE (Helmholtz Pressure Equalizer)

The Concept 50 and Concept 500 are, like all floorstanding loudspeakers, vulnerable to internal build-up of pressure that causes both unwanted standing waves and colouration. To prevent this occurring, specially designed HPE (Helmholtz Pressure Equaliser) tubes are fitted inside the cabinet to nullify internal pressure and improve frequency response.

Bi-wire speaker cable terminals

Each Concept model has bi-wire terminals on the rear of its cabinet. Using appropriate speaker cable, two pairs of cables can connect an amplifier to the speaker - one carries the high-frequency signal, the other carries midrange and low frequencies. Separating these frequencies minimises the intermodulation distortion that arises when using one length of cable to carry the entire frequency range.
