Q Acoustics CONCEPT 300 Silver/Ebony Bookshelf Speakers With Tensegrity Stands

Description

IntroductionSince 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.

There follows a brief explanation of just how Q Acoustics has made this happen and, by extension, why Concept 300 represents the state of the loudspeaker art in the 21st century.

DesignThe 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.

The uncluttered look of the cabinets is further enhanced by innovative drive unit mounting.

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, 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 StandIdeally, 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 Bracingâ„¢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 Gelcoreâ„¢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 SystemWith a standmounting speaker design like this, of course, the speaker’s relationship with its stand is of fundamental importance.

And 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 aluminium 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.
