About this item

Hifi Bookshelf Speakers: Q Concept 30 passive speakers let you feel like you’re listening to your favorite music live. The 0.9″ high-frequency driver is hermetically sealed and mechanically isolated from the front baffle, protecting it from internal resonances from the 5″ mid/bass driver for a truly refined sound.
Quiet Cabinet Design: The stereo speakers’ Gelcore cabinet construction reduces higher frequency noise, while P2P internal bracing stiffens the cabinet to minimize lower frequency vibrations. These innovations improve the focus of stereo images and provide an extended holographic soundstage.
No Interference: The desktop speakers’ isolation suspension base eliminates unwanted external and internal vibrations. The crossover is mounted on the isolation base, keeping it away from electromagnetic fields radiated by the drivers and minimizing any microphonic pickup.

Q Acoustics Q Concept 30

Every element of acoustic innovation featured in Q Acoustics Q Concept 30 is geared toward 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 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 Q Acoustics Q Concept 30, 50, and 90 loudspeakers.

The drive units are fixed to a remarkably stiff 3mm aluminum baffle plate before it is fitted to the cabinet – this gives the correct acoustic seal, dampening vibrations, and minimizing 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 itself is mounted to the isolation base, keeping it free of sound-effecting vibrations and away from the electromagnetic influence of the drivers themselves.

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 aluminum front baffle plate that made the original Concept speakers so iconic. Q Acoustics Q Concept 30 arrives in three striking lacquers

Q Acoustics Q Concept 30 features

Gelcore™ cabinet construction reduces higher-frequency cabinet noise.
P2P™ (Point to Point™) internal bracing stiffens the cabinet to minimize lower frequency vibrations.
Isolation suspension base eradicates unwanted external and internal vibrations.
Q Acoustics Q Concept 30 driver assembly is mounted to the front aluminum baffle by pre-tensioned studs to give the correct acoustic seal while dampening vibrations and minimizing the structural coupling of the assembly in the main cabinet.
Ground-up mid/bass and tweeter driver design for increased power handling.
The 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.
Q Acoustics Q Concept 30 crossover design is mounted on the isolation base, to minimize any microphonic pickup and away from electromagnetic fields radiated by the drive units.
