Q Acoustics have a strong pedigree in producing award winning speakers and the Qi65CB inherits the benefit of this experience. The Qi65CB boasts a carefully designed full range 6.5″ polypropylene driver that delivers a deep, taut bass response, detailed mid-range and extended highs,to ensure an expansive and detailed sound stage. This design choice has the added benefit of being more efficient than traditional designs relying on crossovers,thus increasing its compatibility with partnering amplifiers and requiring less power to perform at higher volumes.
