Description
Overview
The Q Acoustics Concept 90 is the flagship centre channel speaker in the Concept 5.1 home cinema range. It’s designed to deliver ultra-clear dialogue, rich midrange performance, and strong presence for movie effects, thanks to its three-way driver configuration and advanced anti-resonance cabinet technologies.
Key design features include a Gelcore™ cabinet, an isolation suspension base, and a hermetically sealed tweeter enclosure — all aimed at reducing vibrations and cabinet colouration. The Concept 90 is built for clarity even when placed directly on TV furniture.
