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.
The days of performance being the be-all and end-all of a loudspeaker are long gone. Aesthetic considerations are perfectly valid and, to this end, in the Concept 300 Q Acoustics has designed a high-end, high-performance loudspeaker that’s unshowily sophisticated and able to interact discreetly with any interior design vocabulary.
On the outside, numerous lacquer coats produce a high-quality gloss finish which is combined with real-wood veneers. This results in a cabinet that manages to be clean and understated at the same time as being of obviously high perceived value.
At the rear of the speaker, Concept 300 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.
Cabinet and Stand
Ideally, the only vibrations a loudspeaker produces are the ones required to generate its sound. Of course, it’s not possible to entirely rid a loudspeaker cabinet of unwanted vibrations that can interfere with its performance - but, as Q Acoustics has demonstrated with Concept 300, it is possible to keep cabinet vibrations to an absolute minimum in order to deliver entirely uncorrupted sound.
Q Acoustics uses MDF rather than one of the more glamorous and/or expensive alternatives to construct the Concept 300 cabinet. There are a couple of reasons for this: a) alternative materials offer no benefits in terms of damping, or even ease and simplicity of construction, over the very high performance MDF delivers, and b) more expensive materials simply drive up the eventual price of the speaker for no audio gain whatsoever.
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.
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
The design of the new Tensegrity stand, and the new isolation base suspension system that joins Concept 300 to it, 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 precision machined stainless steel rods and thin stainless steel cables. The result is an exceptionally rigid and self-supporting structure with a remarkably low surface area and beautifully elegant appearance.
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.
Driver Units and Crossover
Q Acoustics has taken its proven 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 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.
- Concept 300 redefines the relationship between speaker and stand by using a completely new Tensegrity stand design
- The Tensegrity stands comprise a structure of load bearing solid stainless steel bars to forming an inherently stable tripod
- An Isolation Base Suspension System prevents vibrations moving in either direction through the bottom of the speaker
- Point 2 Point™ cabinet bracing damps the speaker cabinet walls eliminating unwanted energy and reducing distortion
- Dual Gelcore™layered cabinet converts higher-frequency vibrations into heat for ultra-quiet cabinet construction
- High quality drivers, also de-coupled from the cabinet, combine with the crossover to give superior wide dispersion
