Q Acoustics Concept 500 (EISA Award Winner)
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, fine-sounding and astonishingly accurate. It couples low directivity with wide bandwidth, good sensitivity and sensible impedance. This makes the new Concept 500 both room-friendly and an easy load to drive, allowing amplifiers to deliver their best performance.
To create a stereo soundstage which gives as good an impression of width, depth and height as that found in a live performance requires high quality drive units, a well designed crossover and an accurately constructed cabinet. To achieve this, Q Acoustics formed a truly talented team with many years of experience in the design, engineering and manufacture of world-class loudspeakers. A combination that resulted in a state-of-the-art loudspeaker worthy of any high-end system.

Concept 500 is the culmination of Q Acoustics continual
evolution and refinement resulting in what we believe is
near sonic perfection.
Evolution Refinement Perfection.
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.
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.
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.
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.
Tall loudspeakers tend to suffer from resonances caused by
unwanted pressure gradients. Specially designed Helmholtz
Pressure Equalisers (HPE™) balance out these
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 (left) 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™ technology
significantly reduces the ability of the
speaker cabinet to interfere with the accurate
reproduction of the source material.
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.
