KEF R2 Meta Serisi Merkez Hoparlör - TEK

R Serisi Merkez Pasif Hoparlör : R Serisi yer tutucularından herhangi birine uyacak şekilde tasarlanan R2c, filmleri evinizde canlandıran bir diyalog sunar. R2c'nin 125 mm (5 inç) orta kademesi ve 25 mm (1 inç) alüminyum kubbe tweeter Uni-Q, aralığın geri kalanıyla mükemmel şekilde eşleşir. İkiz 130 mm (5,25 inç) bas sürücüleri, harika filmlerin ihtiyaç duyduğu dinamikleri sunar.

Three-way centre channel : Built to match any of the R Series floorstanders the R2c delivers the dialogue that brings movies to life in your home. The R2c's 125mm (5 in.) midrange and 25mm (1 in.) aluminium dome tweeter Uni-Q matches the rest of the range perfectly. Twin 130mm (5.25 in.) bass drivers deliver the dynamics that great movies need.

Uni-Q Driver Array : Developed by KEF in 1988, the Uni-Q driver array acts as a single point source, providing pristine sound across a wider area. The R Series benefits from a new incarnation of this driver array, with advantages over its predecessors that include a new midrange motor system that drastically reduces distortion.

Air moving across the minute gaps between Uni-Q’s separate elements creates tiny resonances, but KEF engineers have reduced the impact of these necessary gaps by opening a cavity behind the drivers and adding resonance-absorbing damping material for more precise, purer treble.

Low Frequency Drivers : The R Series’ dedicated low-frequency drivers have a two-part structure, where a shallow concave aluminium skin sits atop a paper cone. This adds stiffness, while the cone’s unique geometry reduces resonances and delivers the pistonic movement that makes these drivers time so well.The new drivers also have a completely redesigned magnet system that creates a more even magnetic field, and a design of spider that reduces harmonic distortion for a cleaner, more precise sound.

Cabinet Bracing : The R Series benefits from Constrained Layer Damping bracing originally developed for the multiple award-winning LS50, and a new internal bracing layout. This combination brings the R Series closer to the internal structure of the Reference Series, and helps it deliver music as it is supposed to sound, without any unwanted extras.7

Flexible Port Technology : KEF engineers computer-modeled the ideal crossover networks before exhaustively auditioning every high grade component, individually and together, to select those with the lowest distortion and the smoothest response. Perfectionism takes time, but the difference is plain to hear. Nothing is overlooked - Reference crossovers are even mounted on separate boards and decoupled from the cabinet walls to minimize vibration and crosstalk.
