Founded in 2006, Q Acoustics quickly built a reputation for designing and manufacturing class-leading loudspeakers. Concept 500 is the culmination of Q Acoustics continual evolution and refinement resulting in what we believe is near sonic perfection.

The top-of-the-range Concept speaker, this high-end floorstander is designed to appeal to discerning audiophiles. The Concept 500 achieves a perfect balance between art and science. It is a loudspeaker that is at once, stylish, contemporary, exquisite-sounding and astonishingly accurate

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.

Crossover

Great care has been taken in both the design of the crossover and the selection of high grade components, to introduce virtually zero noise and distortion. The 4th-order Linkwitz-Riley topology which gives an excellent response both on and off-axis.

Cabinet Bracing

A method, known as P2P™ (Point to Point) bracing, supports the parts of the cabinet that need to be stiffened to deal with low frequency panel vibrations.

Cabinet Walls

Constructed in three separate layers and filled under pressure with a non-setting gel, this damps the cabinet walls and converts higher frequency vibrations into heat.

High Frequency Driver

Mechanically decoupled mounting which effectively isolates the HF driver and speaker cabinet from reciprocal vibrations that would otherwise be transmitted between them.

Mid/Bass Drivers

The Mid/Bass voice coil has an uncommonly large diameter of 35mm which allows increased ‘shove’ and higher power handling - as well as reducing compression.

Pressure Equalisers

Tall loudspeakers tend to suffer from resonances caused by unwanted pressure gradients. Specially designed Helmholtz Pressure Equalisers (HPE™) balance out these pressure irregularities.

Dual Gelcore™

The speaker cabinet is constructed in three separate layers. The gaps between the layers are completely filled under pressure with a compliant form of non-setting gel. The two constrained layers effectively damp the walls of the speaker cabinet by converting higher frequency vibrations into heat, which is then dissipated harmlessly within the damping gel.

The graph shows how the cabinet performs in the mid-band frequency area from 500Hz to 2kHz. The blue line shows the amount of unwanted sound energy produced by the wall of a conventional loudspeaker cabinet.

Any erroneous boost or cut in level at this frequency can affect the perception of musical timbre and contribute to listener fatigue. You can see from the trace of the red line how the addition of Dual Gelcore™

The objective of any good Hi-Fi system is to reproduce a convincing live performance in the comfort of your home. The Concept 500 adopts some of the most advanced and innovative technologies to deliver pure audio excellence and a sensational sound stage.

Neutral, powerful and dynamic.
