Concept 30 Bookshelf Speaker Pair
No artificial colouring
Every element of acoustic innovation featured in the Concept 30 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.
All our anti-resonance innovations allow the state-of-the-art complement of drivers free to get on with the job of delivering the most realistic, most involving sound ever heard at this price-point.
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.
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.
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
A variation on the hugely effective ‘isolation base’ principle first seen on Concept 300 means the Concept 30 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.
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 (amplifer) 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 minimised, with the result being noticeable improvement in the clarity of the mid-range.
