| Other Features | Discover the new iteration of this speaker with Metamaterial Absorption Technology ( MATâ„¢ ).
With a Uni-Q mid and treble backed up by a bass driver and two ABRs the Q750 is built to deliver total musical enjoyment.
Pairing the KEF signature Uni-Q driver array with a 165mm ( 6.5 inch ) aluminium bass driver and two matching ABRs, the Q750 delivers astonishing sound quality.
Q750 is the intermediate model for the Q Series floorstanders. Featuring the KEF signature Uni-Q driver array paired with an impressive 165mm (6.5 inch) aluminum bass driver and two matching ABRs, the Q750 combines astonishing sonic reproduction with powerful room filling bass. | KEF's 12th Generation Uni-Q driver acts as a single point source to disperse sound more evenly for an immersive and cohesive soundstage with better clarity.
Q Concerto features KEF's revolutionary Meta material technology that can absorb 99% of the unwanted noise from the rear of the driver for pure and natural sound.
The Q Series speakers feature a contemporary minimalist design with a satin finish that offers a premium, subtle glow. Available in Satin Black, Satin White, and Walnut finishes, they are designed to blend effortlessly into any interior.
A critical component of the Q series is the refined crossover, which ensures seamless integration of all speaker parts. More than 1,000 specific measurements are taken for each speaker model, allowing precise signal path and optimisation for best possible performance.
The Q Series features a hybrid bass driver design that provides stiffness to achieve a piston-like movement for better bass punch and speed. Combined with a port modelled using Computational Fluid Dynamics, this results in precise and agile bass management even at high output levels. |
