Q Acoustics is proud to introduce the new Concept 20 Loudspeaker. The 'Concept 20' is a special loudspeaker which goes beyond anything that Q Acoustics has achieved before. It's a beautifully styled product which we confidently believe delivers a level of sonic performance previously thought impossible at its price point." To achieve this extraordinary performance, Q Acoustics' design team applied scientific methodology and advances in technology to address the problem of cabinet resonance; long recognised as the single biggest hurdle preventing speaker designers delivering true 'high end' performance at a reasonable price. What is Gelcore The 'Concept 20' proves cabinet resonance need be a problem no longer.* Incorporating a 'cabinet within a cabinet' design, its inner and outer enclosures are bound together by a bespoke adhesive which never quite sets. This configuration (known as Gelcore™ construction) allows the kinetic energy generated by the drive units within the cabinet to be dispersed as heat and preventing them colouring and degrading the speaker's musical output. The 'cabinet within a cabinet' Gelcore™ construction dramatically reduces resonances and colouration. Combine this new cabinet design with the Concept 20's advanced, high dynamic, low distortion drive units and the result is a loudspeaker which, at its price, is nothing short of sensational." Sonically Matching Floorstand To optimise sonic performance, we have also incorporated Gelcore(TM) Construction into a unique, visually striking and resonance-free matching floorstand for the new loudspeaker. The beautiful Concept 20 speakers and high performance stands come in a choice of either Gloss White or Gloss Black, lacquered finishes. *When compared to a good conventional cabinet, radiated power (colouration) throughout the critical mid-band (voice frequencies) reduces by an average of more than -6dB. In the high and low frequencies the effect is even greater, with improvements in excess of -10dB.
