When an idea becomes a concept.

  • British audio specialists Q Acoustics launches the Concept 300 standmount speaker which features leading-edge acoustic and Tensegrity speaker stand technology.
    Q Acoustics introduces the Concept 300, which incorporates and refines many of the design features that made its flagship Concept 500 a success.

    Audio design innovations include:
    • Dual Gelcore™ cabinet construction
    • Internal P2P™ (Point to Point) bracing
    • Tensegrity tripod stand
    • Isolation base suspension system
    • Spring-tension fitted drivers
    • New stylish silver and ebony dual finish

    The cabinet construction employs the same Dual Gelcore approach and internal P2P (Point-to-Point) bracing found in the Concept 500. This comprises of three individual layers which are separated by a non-setting gel. This bespoke adhesive dissipates the high-frequency vibrations generated by the moving drivers as heat, to maintain performance. The P2P bracing is fitted to interior areas of the cabinet susceptible to low-end frequency reverberations and helps to further eradicate sound-degrading internal vibrations.

    The unique and striking Tensegrity tripod stand also further reduces the transmission of vibrations by providing a stable support system for the speaker. Constructed from aluminium rods and thin stainless-steel cables, this self-supporting structure has its constituent elements subject to either compression (tubes) or tension (cables) and is never subjected to bending forces. The outcome is a low surface area that eliminates radiating sound and reflections.

    Please note the loudspeaker and Tensegrity stand are not sold separately.


    The new isolation base plate system, integrated into the bottom of the Concept 300 cabinet, connects the speaker to the stand in a way that minimises vibrational energy and which maintains an accurate audio performance. 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. This polyurethane elastomer, tailored to the mass of the speaker, converts any vibrational energy in the springs into heat. The result is a controlled bass response and improved stereo imaging.


    The Concept 300 preserves its flagship looks and keeps the facade free from unsightly bolt-heads by holding the mid/bass driver unit 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, thereby maintaining a consistent performance.

    By using the wide-dispersion high-frequency driver and isolating mount developed for Concept 500, the 300’s tweeter is protected from sending or receiving unwanted vibrations which allows it to be mounted close to the mid-bass driver, enhancing integration and improving timing.

    The Q Acoustics Concept 300 combines real wood veneers with multiple gloss lacquer in a new Silver/Ebony finish which gives a premium feel. It joins the Gloss Black/Rosewood, Gloss White/Oak finishes and all are available (including Tensegrity stand) from March 2019, priced £2,999 / €3,749 / $4,499 (SRP).
