Concept 50 5.1 Home Cinema


Concept 50 5.1 Home Cinema

Bringing scale and widescreen sound to home movie-watching experience, this package ramps up the intensity and entertainment levels to command your attention.

A pair of Concept 50 floorstanding speakers at the front end intensifies the power and dynamics, all without sacrificing any insight and subtlety. This 5.1 set-up is as agile and sophisticated as it is commanding and all-encompassing.

  • Gelcore™ cabinet construction reduces higher frequency cabinet noise.
  • P2P™ (Point to Point™) internal bracing stiffens the cabinet to minimise lower frequency vibrations.
  • Isolation suspension base eradicates unwanted external and internal vibrations.
  • The driver assembly is mounted to the front aluminium baffle by pretensioned studs to give the correct acoustic seal, while dampen vibrations and minimise 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 minimise any microphonic pick up and away from electro-magnetic fields radiated by the drive units.

Concept 50 5.1 Home Cinema

Home cinema maestro

Our flagship 5.1 home cinema speaker package is comprised of a pair of Concept 50 floorstanders at the front, a pair of Concept 30 standmounts positioned at the rear, with a Concept 90 centre channel focused on dialogue. Finally, our most powerful subwoofer, the Q B12, provides the low-end sonics.

Surround sound movie experience in the home

All these speaker models (except Q B12 subwoofer) harbour many anti-resonance technologies that contributed to delivering the most realistic, enthralling and enveloping 5.1 surround sound movie experience in the home.

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 aluminium baffle plate before it is fitted to the cabinet - this gives the correct acoustic seal, dampening vibrations and minimising structural coupling.

Hermetically sealed and mechanically isolated
Hermetically sealed and mechanically isolated

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 (Concept 50 model only)

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.

With all the cabinets boasting a premium and luxurious high-gloss finish, this speaker array will fit neatly into any interior design environment. The Concept 50 5.1 arrives in two choices of finish – white or black. A range of optional accessories are also available for this package:The Q WB75 bracket lets you wall mount the Concept 30 and 90 with a 'tilt and turn' mechanism that allows flat to the wall, angled down or sideways positioning.


Inspired by the Concept 300’s Tensegrity design, the striking Q FS75 stand is compatible with the Concept 30 should you need perch these rear speakers on a stand.

Gelcore™ technology
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
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 Q Acoustics Q WB75 bracket
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..

Q B12 subwoofer; bass frequencies are substantially omni-directional. Although this means that you can position the subwoofer almost anywhere, the stereo image will still benefit from positioning the subwoofer in line with the front loudspeakers and as central to the listening position as possible. However, this may not be feasible in a multichannel system. If you place the subwoofer too close to a wall the bass will be reinforced, therefore in some locations the bass may be boomy and indistinct.
