Description
Q Acoustics Concept 30 Bookshelf Speakers
The Q Acoustics Concept 30 Bookshelf Speakers were designed as an integral part of the mechanical structure of the cabinet, both the mid/bass and 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.

Review
Hi-Fi Choice
“In my review of the M20, I briefly embarked on an extended and possibly tortuous fried chicken metaphor to note that when Q Acoustics adheres to some core principles, the results are frequently untouchable. It’s hard to make any argument about the Concept 30 that dents this position. The new ideas at work here serve to refine the core processes that the company has made its own and have resulted in a speaker that is a genuinely spectacular arrival at the price point.
How spectacular? Well, consider this. When I reviewed the LS50 Meta I celebrated its technical excellence but noted that it came at the price of being a fairly demanding piece of equipment in its own right. This is why it proceeded to lose out to the Lumina II for the 2021 Editor’s Choice. The Sonus faber is far less sophisticated but the results of the careful application of sensible engineering led to a speaker that was more fun and rather easier to live with, if not as devastatingly capable in terms of imaging and impact. The Concept 30 arrives, bridging the gap in a manner that is unlikely but deeply impressive. It’s as technically accomplished as the LS50 Meta, at the same time retaining the joy, ease of drive and general bonhomie of the Lumina II while costing £100 less than either of them. It’s all things to all people and a well-deserved Best in Class.” Ed Selley, reviewing the Concept 30s for Hi-Fi Choice
Darko Audio
The Q Acoustics Concept 30 is positively reviewed on Darko Audio, going up against the KEF LS50 Meta and Sonus Faber Lumina II in a comparison test. View both in the Concept 30 section in the Coverage Book.
Quote: “I think it’s fantastic that a relatively new company like Q Acoustics have managed to position themselves on par with KEF and Sonus Faber – it’s brilliant, well done to them.”
Key Features
- 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.
No artificial colouring
Every element of acoustic innovation featured in the Q Acoustics Concept 30 Bookshelf Speakers are 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.
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 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 Q Acoustics Concept 30 Bookshelf Speakers 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.
