A star role in home cinema
At the heart of a Concept 5.1 home cinema set-up, the Concept 90 is Q Acoustic's most high-performance centre channel speaker yet. Able to deliver astonishingly dynamic and ultra-clear dialogue, this speaker is the star of the Concept home cinema range. A centre channel speaker in a 5.1 home cinema set-up plays a crucial role to convey a realistic surround sound experience. More than just supporting the front left and right channel speakers, a centre channel anchors the dialogue while also seamlessly being part of the whole soundstage.
Controlled power
Boasting a three-way design with two 125mm mid/bass drivers flanking a 25mm tweeter, the Concept 90 brings ultra-clear dialogue and spellbinding effects to movie watching sessions through it specially developed driver designs. With sound synergy important in a home cinema speaker system, the Concept 90 harbours the same hermitically sealed and decoupled tweeter enclosure and driver assembly baffle-mounted design as the Concept 30 and 50. The same isolation base, featuring two plates separated by suspension spheres, is also present to isolate the cabinet from external resonances – a crucial design when the speaker is placed straight onto a TV cabinet, while also providing tighter audio, and greater depth to your music and movies.
All of these resonance eliminating innovations are housed in a Gelcore™ cabinet design to deliver a speaker low on interior influences that can colour the sound. It ensures the Concept 90 can dispatch crystal clear dialogue and improved depth of sound that will elevate the film watching experience. Introduced in the original Concept speaker, the Gelcore™ cabinet construction is designed to minimise high-frequency noise. A unique design comprised of a non-setting gel sandwiched between two individual layers, this specially developed adhesive dissipates high-frequency vibrations, generated by the moving drivers, into heat to maintain a focused audio performance, whether watching movies or listening to music.
