Concept 50 Floorstanding Speaker


  • Gelcore™
    cabinet construction reduces higher frequency cabinet noise.
  • P2P™
    (Point to Point™) internal bracing stiffens the cabinet to minimize lower
    frequency vibrations.
  • HPE™
    (Helmholtz Pressure Equalizer™) reduces internal pressure and standing
  • Isolation
    suspension base eradicates unwanted external and internal vibrations.
  • The
    driver assembly is mounted to the front aluminum baffle by pretensioned
    studs to give the correct acoustic seal, while dampen vibrations and minimize
    structural coupling of the assembly in main cabinet.
  • Ground-up
    mid/bass and tweeter driver design for increased power handling.
  • High-frequency
    driver is fully hermetically sealed and mechanically isolated (floating)
    from the front baffle to protect from internal resonances from the
    mid/bass driver.
  • Crossover
    design is mounted on the isolation base, to minimize any microphonic pick
    up and away from electro-magnetic fields radiated by the drive units.

No artificial coloring

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

Controlled power

Designed as an integral part of the mechanical structure of
the cabinet, both the 5-inch mid/bass and 0.9-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 aluminum baffle plate before it
is fitted to the cabinet – this gives the correct acoustic seal, dampening
vibrations and minimizing 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 aluminum 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 minimize 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

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 (amplifier) 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 minimized,
with the result being noticeable improvement in the clarity of the mid-range.
