Since its founding in 2006, Q Acoustics has built an unrivalled reputation for designing, engineering and manufacturing innovative, high-performance and class-leading loudspeakers at every price-point.
On the outside, numerous lacquer coats produce a high-quality gloss finish which is combined with real-wood veneers. Both the tweeter and mid/bass driver are fixed, from behind, by strong spring-tensioned retaining bolts which negate the need for any exposed bolt-heads on the speaker face. At the rear of the speaker features an over-specified terminal panel which is designed to resist vibrations from the cabinet. It’s equipped for bi-wiring (or bi-amping) via its electrically isolated terminals – these can accept bare wire, spade connectors or 4mm banana plugs.
The intelligent of the design of the Concept 300 cabinet is evident in its use of P2P (point to point) bracing, measuring the performance of the cabinet structure at a microscopic level, and identifies the precise positions that require support. Having dealt with lower-frequency vibrations using P2P bracing, Q Acoustics then negates higher-frequency cabinet vibrations using its bespoke Dual Gelcore technology. The cabinet is comprised of three individual layers, each separated by a non-setting gel – the gel acts rather like a high-tech and extremely effective gasket. Any stray high-frequency vibrations are converted into heat which dissipates within the gel.
The mid/bass driver is a 165mm impregnated/coated paper cone with very low resonance thanks to its high-performance rubber surround. It sits in front of a large (35mm) glass fibre voice coil and equally substantial ferrite magnet. The result is midrange and bass response that’s as punchy and dynamic as it is poised and eloquent.
Above it, the 28mm high-frequency driver, made of super-fine strands of coated microfibre, is decoupled from the speaker cabinet using a rubber gasket. This protects the tweeter from sending or receiving unwanted vibrations and allows it to be mounted close to the mid-bass driver. This improves integration with the larger driver – and the very subtle horn-shaped profile to the tweeter’s front plate allows perfect impedance-matching with its environment without colouring performance.
