Product Description
KEF R2 Meta centre speaker is designed to voice perfectly with other R series Meta speakers to integrate perfectly into a multi-channel speaker setup. It has been upgraded with Metamaterial in the Uni-Q driver array, for even better performance.
Of course a good quality centre speaker is vitally important to accurately deliver the dialogue that makes movies and games more immersive. R2 Meta has a 25mm aluminium dome tweeter and a 125mm midrange speaker in one unit. That is the Uni-Q array. There are also two 130mm bass drivers for excellent impact and dynamics.
Metamaterial Absorption technology (Meta)
Meta material is a material that has had its characteristics changed so that it behaves in a different way to the same material’s solid form. In the case of the KEF damping material, ABS plastic has been modified to act as an almost perfect sound absorber. A moulded component made of this material has been placed behind the tweeter element in the Uni-Q array. This is designed to prevent any high frequency sound from interfering with the midrange unit. As a result, distortion is reduced and the sound should have more accurate detail.
Excellent Centre Performance
The R2 Meta centre speaker has an impressive frequency range of 74Hz-28kHz (±3dB). Power handling is 200w. High and mid frequencies are handled by the KEF designed Uni-Q array. This is a two way speaker that is the latest in a long line of centre speakers that have been improved over many years of research and development.
Uni-Q Driver Array
The Uni-Q driver array is used throughout the R series. It combines a 25mm aluminium dome tweeter with a 125mm midrange unit. This creates a single point source for more dispersed sound. The motor system that drives the diaphragm has been upgraded. The pole has been modified and it now has symmetrical aluminium demodulation rings. As a result voice coil impedance variations have been reduced for more natural vocals.
130mm Bass Units
A two part cone structure is used for the R2 Meta bass drivers. A concave aluminium skin is bonded to an underlying paper cone. This makes for a very rigid structure that resists deformation. As a result bass should be tighter and resonances are reduced. There is also a new magnet system in the motor. This improves the evenness of the magnetic field. The suspension has been redesigned to reduce distortion. Overall the result should be less chance of coloration and more accurate sound.
Rigid Cabinet Geometry
The R series cabinets use Constrained Layer Damping bracing. A flexible material is used to join the baffle elements. This material dissipates unwanted vibrations and this bracing layout creates a very inert structure. In this way a very solid vibration free platform is created for the drivers.
The KEF R series Meta
KEF make a range of speakers for the home as well as professional architectural speakers. The R series sits in the middle of the domestic speaker range with three floor standers as well as one set of stand mounted speakers. There is also a centre speaker and a subwoofer. Now with Meta materials, the R series Meta range should be the best sounding R series range to date.
