The successors to our renowned, award-winning HiFi speaker range, the Q Series has evolved once more in its 9th iteration since 1991. Now incorporating the revolutionary Metamaterial Absorption Technology (MAT™) and a suite of innovative acoustic technology derived from our flagship HiFi speakers, high fidelity sound is more accessible than ever. Leveraging the latest 12th generation Uni-Q driver array and cutting-edge analysis techniques, the Q Series has been carefully fine-tuned. This includes a crossover redesign that refines the signal path response for a more natural, detailed sound.

Revolutionary sound absorption with MAT™
The crucial new advancement in the Q Series is the integration of Metamaterial Absorption Technology (MAT), a revolutionary innovation that takes the performance of the latest 12th generation Uni-Q driver array to another level in terms of accuracy and clarity.
MAT is a highly complex maze-like structure, in which each of the intricate channels efficiently absorbs a specific frequency. When combined, the channels act as an acoustic black hole, absorbing 99% of the unwanted sound that comes from the rear of the tweeter. This eliminates the resulting distortion for a purer, more natural acoustic performance.
Superior KEF sound
The latest 12th generation Uni-Q driver array with MAT is found in all eight models of the Q Series and delivers an incredibly detailed performance. It’s the result of decades of accumulated in-house knowledge and the application of state-of-the-art simulation and analysis tools. The developments are many and all play a part in the Q Series’ impressive performance.
The Uni-Q driver array has been redesigned to maximise the performance improvements that MAT delivers. The conical waveguide that couples the tweeter dome to the metamaterial absorber has been specially designed for the driver based on its depth. The re-engineered tweeter gap damper strategically places two rings of porous material to tame the resonances and imperfections effectively, greatly improving detail and clarity.
An extra half way
The evolved Q Series has been upgraded from a 2.5-way to a 3-way speaker design. This updated configuration separates the frequency ranges, with the Uni-Q driver handling the high and midrange frequencies, and a newly designed bass driver dedicated to the low frequencies management.
The optimisation of the drivers for their respective frequency bands allows the 12th Uni-Q driver to perform even better. By minimising the motion of the mid-frequency cone, the tweeter can transmit high frequency sound over a smoother and more stable surface. This reduction in movement leads to a diminished distortion in the lower midrange frequencies, resulting in a significant improvement in detail and clarity
Deep and clean bass
The Q Series features a new bass driver design – a hybrid structure with a shallow, concave, aluminium skin atop a paper cone – which gives stiffness to achieve a piston-like movement for better bass punch and speed. Combined with a 3D FEA-optimised surround geometry, this significantly improves linearity at higher excursions. This results in a precise and agile bass management even at high output.
Additionally, the flared port, modelled with computational fluid dynamics, minimises turbulence and reduces chuffing noise. This enables the ported speakers to produce bass that is cleaner and more controlled
