Q Acoustics Concept 20 looks like a standard compact loudspeaker, but offers a few technological specialities. First of all, there is the casing which consists of two casings which are nested into each other and feature a gel layer in between. This construction kills off any sound-distorting vibration, because the normal vibrations are transferred into warmth by the gel layer. This brings the compact two way speaker to an acoustic top performance. With matching stands, which also features this so called Gelcore technology in their upper part, the Concept 20 are brought to listening level, thus enhancing the sound quality even further.
