Q ACOUSTICS CONCEPT 300 FLAGSHIP STAND-MOUNT SPEAKERS

Q Acoustics unveiled their most advanced loudspeaker, the Concept 300, at London's Cornflake Shop. Prepare to want.
Q Acoustics’ flagship loudspeaker, the award-winning Concept 500 floorstander, proved what was possible to achieve while keeping the price well within the realms of most audiophile's pockets.
Building on the success of its flagship model the company has developed the groundbreaking Concept 300.
The Concept 300 sports real wood veneers with multiple gloss lacquer, the dual finish is merely the beginning of the high-desirability factor of these new stand-mounts.
Q Acoustics Concept 300 Design
The Concept 300 employs the same Dual Gelcore cabinet construction and internal P2P (Point-to-Point) bracing found in the Concept 500. Comprising of three individual layers, separated by a specially developed non-setting gel, this special bespoke adhesive dissipates high-frequency vibrations, generated by the moving drivers, into heat to maintain a focused audio performance.
Furthermore, there's the unique and innovative Tensegrity tripod stand. Not only does this add to the overall modern aesthetic, but the stand is also integral to further reducing the transmission of vibrations and providing a stable support system for the speaker.
The oddly-named stands consist of load-bearing low-profile aluminium rods and thin stainless-steel cables that define and maintain the spatial orientation of the rods. The self-supporting structure, made up of elements either in compression (tubes) or tension (cables), is never subjected to bending force. The outcome here is a low surface area that eliminates radiating sound and reflections for a purer sonic performance.
Rigidly coupling a speaker to a stand is crucial to minimising the intensity of vibrational energy and maintain an accurate audio performance. Q Acoustics’ expert engineers have developed the Isolation base plate system and integrated it into the bottom of the Concept 300 cabinet. Not only does it securely anchor the cabinet to the stand but provides a flexible suspension system.
The entire mass of the speaker rests on four springs, damped using a special material called Sylodamp (we love these names). A polyurethane elastomer, precisely tailored to the mass of the speaker converts any vibrational energy in the springs into heat. The result is a more controlled but extended bass response and improved stereo imaging.
Smooth Operator
To preserve the sleek, minimalist design, the facade is kept free from unsightly bolt-heads. The Concept 300 has the mid/bass driver unit held in place from behind by strong spring-tensioned retaining bolts. Not only does this remove the need for vibration-attracting decorative trim to hide the screws but it keeps the torque constant with no adjustment needed throughout its lifetime, maintaining consistent performance.
The Concept 300 also features the wide-dispersion high-frequency driver and isolating mount developed for Concept 500. Again, a design that protects the tweeter from sending or receiving unwanted vibrations and allows it to be mounted close to the mid-bass driver, enhancing integration with the larger mid/bass driver and improving timing.
Price and availability
The Q Acoustics Concept 300 dual finish model (including Tensegrity stand) comes in three finishes: Gloss Black/Rosewood, Gloss White/Oak and Silver/Ebony and is available from March 2019, priced £2,999 / €3,749 / $4,499 (SRP).

applause awards
Each time StereoNET reviews a product, it is considered for an Applause Award. Winning one marks it out as a design of great quality and distinction – a special product in its class, on the grounds of either performance, value for money, or usually both.
Applause Awards are personally issued by StereoNET’s global Editor-in-Chief, David Price – who has over three decades of experience reviewing hi-fi products at the highest level – after consulting with our senior editorial team. They are not automatically given with all reviews, nor can manufacturers purchase them.
The StereoNET editorial team includes some of the world’s most experienced and respected hi-fi journalists with a vast wealth of knowledge. Some have edited popular English language hi-fi magazines, and others have been senior contributors to famous audio journals stretching back to the late 1970s. And we also employ professional IT and home theatre specialists who work at the cutting edge of today’s technology.
We believe that no other online hi-fi and home cinema resource offers such expert knowledge, so when StereoNET gives an Applause Award, it is a trustworthy hallmark of quality. Receiving such an award is the prerequisite to becoming eligible for our annual Product of the Year awards, awarded only to the finest designs in their respective categories. Buyers of hi-fi, home cinema, and headphones can be sure that a StereoNET Applause Award winner is worthy of your most serious attention.
