Taking acoustic technology and design cues from the flagship Concept 300, while also introducing new audio innovations, the Q Acoustics Concept 30 Bookshelf Speakers deliver truly high-end home audio performance.
No artificial colouring
Suited to larger spaces, the Concept 30 offers a truly high-end home audio performance without the high-end price tag. Every element of acoustic innovation featured in the Q Acoustics Concept 30 goes towards designing the quietest cabinet possible. Unaffected by internal and external resonances, these speakers deliver focused stereo imaging, accurate audio and an extended soundstage.
Boasting a higher sensitivity for enhanced dynamics, this floorstander thrills with both its sheer musicality and uncannily realistic soundstage.
Controlled power
Designed as an integral part of the cabinet’s mechanical structure, the 5-inch mid/bass and 1.0-inch tweeter drivers are new, ground-up designs specifically for the Concept 30, 50, and 90 speakers. The drive units are fixed to a remarkably stiff 3mm aluminium baffle plate before they are 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 a 25.4 mm voice coil.
Lastly, the crossover mounts to the isolation base, keeping it free of sound-effecting vibrations and away from electromagnetic influence.
HPE (Helmholtz Pressure Equalizer) technology
The very nature of the Concept 30 tower design can introduce undesirable standing waves within the cabinet. An HPE tube design launched in the Concept 300 converts pressure to velocity to eliminate these performance-affectingย vibrations and 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 aluminium front baffle plate that made the original Concept speakers so iconic. The Q Acoustics Concept 30 Bookshelf Speakers arrive in three striking lacquers: black, silver and white.
Gelcore technology
Introduced in the original Concept speaker, the Gelcore cabinet construction minimises high-frequency noise. A unique design comprised of a non-setting gel sandwiched between two individual layers, this specially developed adhesive also 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 โisolation baseโ principle first seen on Concept 300 means the Concept 30 speakers have a suspension system as a sprung baseplate. Suspension โspheresโ separate two plates, effectively isolating the cabinet from interference from external vibrations, providing tighter stereo imaging and depth.
P2P (Point to Point) technology
P2P (point-to-point) internal bracing keeps the cabinet as rigid as possible. Firstly introduced in the Concept 300, reinforcement is fitted to interior areas of the cabinet susceptible to low-end frequency reverberations.
The speaker cabinet’s performance is examined down to the microscopic level using P2P bracing, finite element analysis, and laser interferometry.
Implementing this state-of-the-art technology, Q Acoustics has been able to identify and apply bracing to only the precise points of the cabinet that require additional support, dissipating unwanted energy rather than transferring it throughout the cabinet.
