- 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.

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.
Elegant design
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 30 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 front and rear speakers on stands.
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 aluminium baffle plate before it is fitted to the cabinet – this gives the correct acoustic seal, dampening vibrations and minimising 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.
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.
