Q Acoustics has added to its popular Concept speaker range with the Concept 30 standmount, Concept 50 floorstanding and Concept 90 centre channel.

The latest additions to the Q Acoustics Concept series naturally take design cues and technology from the pioneering flagship Concept 300 and 500 speakers, such as the Gelcore cabinet and Point-2-Point internal bracing. However, we are told that the new models also introduce new state-of-the-art audio innovations to "deliver truly high-end home audio performance without the high-end price tag", says the brand.

As well as the gel sandwich cabinet construction and internal bracing, the new models sport a variation of the 'isolation base' principle first seen on Concept 300, where two plates are separated by suspension 'spheres' that effectively isolates the cabinet from interference from external vibrations. This promises tighter stereo imaging while also bringing greater depth.

Tall floorstanding speakers are prone to an internal build-up of pressure that causes unwanted standing waves and reverberations. To prevent this, specially designed Helmholtz Pressure Equalisers (HPE) tubes are fitted inside the Concept 50's cabinet to improve frequency response. Q Acoustics states that all these 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 fitting to the cabinet. We are told that this gives the correct acoustic seal, dampening vibrations and minimising structural coupling.

Additionally, the tweeter is hermetically sealed and mechanically isolated (floating) from the baffle, which should mean 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.

As well as two-channel listening, Q Acoustics offers the Concept 50 5.1 speaker package comprising a pair of Concept 50 floorstanders at the front, a couple of Concept 30 standmounts for the rear, and a Concept 90 centre channel focused on dialogue. Finally, the Q B12 subwoofer is on duty for low-end sonics.

All models arrive in three striking lacquers: black, silver, and white and are available from the end of October 2021 with the Q Acoustics Concept 30 priced USD $1,299, the Concept 50 at USD $2,999 and Concept 90 at USD $999. The Q Acoustics Concept 50 5.1 package (2x Concept 50, 2x Concept 30 1x Concept 90, 1x QB12) is priced USD $6,295.
