IQ PSW 2500 (2940 euro) managed the KEF set a hyper-accurate spatial presentation, which added a unique dimension to the concept of homogeneity. No other set could so easily distinguish between speech, music and sounds.
The name KEF, so testers look regularly led to swarm that precisely accommodate the tweeter in the center of the bass-midrange speaker from the inherent advantages of the brand-typical uni-Q systems and not as otherwise usual far apart.
The coaxial design, implementing them in practice due to diverse interactions represents a major challenge, has the virtue of one horizontal like vertical identical beam behavior, what facilitates the construction of flat Center and benefits also tangible sound when listeners (in multichannel more often) not exactly sit in front of their boxes “on axis”.
The recently revised iQ series features the latest generation of uni-Q, based on over 20 years development, increasingly complex computing models are based. It is a jagged diffuser lens that prevents sound waves from the closely adjacent sound sources interfere with each other.
90 iQ and iQ 30 (front and rear set) use a 16 cm-large variant of the uni-Q, the center of the lower overall height because of a smaller size 13. At the front Peakern, two separate bass driver are added, which ensures dynamic reserves will hardly credible in the sum.
A hyper-accurate spatial presentation, which added a unique dimension to the concept of homogeneity was the KEF Kit. No other set could so easily distinguish between speech, music and sounds, so of course resolve fine branching, or trace across the room so sustained wandering sound events.
The tester by the assertiveness of the Woofer and bass precision the iQ of 90 were not so intoxicated. What did hardly influence the incentives of the set because it directs the focus as if by magic on the artistically important content, which have little of the hat with bass Bolzerei. And because it is technically not a problem, in terms of subwoofer to look elsewhere.
