Uncompromised Performance, Understated Elegance
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. This ongoing and concerted demonstration of excellence has all led to Concept 300. The brief for Concept 300 is simple, yet staggeringly ambitious. Build on the runaway success of the floorstanding Concept 500 and deliver a standmounting alternative that’s at once more affordable, of utterly uncompromised performance and of stylish, understated elegance.
Features
- The intelligence of the design of the Concept 300 cabinet is evident in its use of P2P (point to point) bracing
- Concept 300 features an over-specified terminal panel which is designed to resist vibrations from the cabinet
- Having dealt with lower-frequency vibrations using P2P bracing, Q Acoustics then negates higher-frequency cabinet vibrations using its bespoke Dual Gelcore technology
- Mid/bass driver is a 165mm impregnated/coated paper cone with very low resonance thanks to its high-performance rubber surround
- Large (35mm) glass fiber voice coil and equally substantial ferrite magnet
Point 2 Point Bracing™
The intelligence of the design of the Concept 300 cabinet is evident in its use of P2P (point to point) bracing. Q Acoustics is able to measure the performance of the cabinet structure at a microscopic level, and identifies the precise positions that require support. So the P2P targeted cabinet-bracing method means the cabinet has exactly the support it needs, and no more. In this instance, a long and involved analysis of a problem results in a simple and brilliantly effective solution.
Dual Gelcore™
Having dealt with lower-frequency vibrations using P2P bracing, Q Acoustics then negates higher-frequency cabinet vibrations using its bespoke Dual Gelcore technology. The Concept 300 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.
Tensegrity Stand & Isolation Base System
With a standmounting speaker design like this, of course, the speaker’s relationship with its stand is of fundamental importance. It’s the design of the new Tensegrity stand, and the new isolation base suspension system that joins Concept 300 to it, that allows Q Acoustics to redefine the level of performance that’s possible from a smaller loudspeaker.
Tensegrity is a tripod - by definition, an extremely stable structure. It’s built from lightweight aluminum tubes (which are the load-bearing element) and thin stainless-steel cables (which maintain the position of the load-bearing tubes). The result is a light, exceptionally rigid and self-supporting structure with a remarkably low surface area and - let’s not pretend otherwise - beautifully elegant appearance. It’s not so much a speaker stand, it’s more an entirely new loudspeaker support concept. But, of course, it’s of little consequence how efficient your speaker cabinet is, or how ingenious the design of the stand it works from, if the union between the two is unsympathetic or inefficient. Q Acoustics joins Concept 300 speaker to Tensegrity stand with the new isolation base suspension system, which is about as sympathetic and efficient as it gets.
The entire mass of Concept 300 is suspended on the four springs of the newly developed integrated base plate. This isolation base system works in multiple ways: it prevents energy from the speaker leaking into the Tensegrity stand and affecting the sound, it prevents vibrations for the floor making their way from the stands into the speaker, and in every circumstance, it provides a rigid coupling between speaker and stand. Thanks to the combination of Tensegrity stand and isolation base suspension, the performance of Concept 300 is entirely unhindered by internal or external influences.
Driver Units and Crossover
Q Acoustics has taken its proven (and acclaimed) driver technology from the Concept 500 floorstanding speaker and enhanced its performance to perfectly match the requirements of the Concept 300’s smaller cabinet. 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 fiber 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 microfiber, 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 coloring performance.
