KEF’s research group has being steadily developing considerable expertise in the in the use of advanced acoustical, magnetic and mechanical modelling techniques. These techniques, such as Finite Element Analysis, allow acoustic systems to be modelled to an accuracy not previously achievable using other methods. Drive units for example, with their complex vibrating parts, are now prototyped and optimised in the virtual domain, allowing many options to be investigated before a real physical sample needs to be made. The fruits of this capability can be seen in the latest generation of Uni-Q driver arrays from the 4.5 inch KHT3005 version with its ribbed cone and sealed suspension technology to the latest 6.5 inch Reference Range Uni-Q with its optimised geometry, wide dispersion tweeter section.

Now under in its 5th decade, KEF is still developing world-beating products. Scientific innovation and hands-on experimentation continue to underwrite its reputation as the audiophile’s ultimate loudspeaker manufacturer.
