KEF iQ50 in combination with Universal Wireless Amplifier System

Introduction

Wireless Goes High Fidelity: Many providers have already tried to practically integrate wireless speaker and amplifier systems phonetically "presentable" to make. Lack of acoustic brilliance, an unsatisfactory impression of space, audible noise and patchy conceptual approaches have in most cases, however, ensured that the dissemination of such market solutions was rather low. With much cleverness and high quality has now KEF goal, finally convincing aural wireless system to offer: For 599 EUR is "Universal Wireless" in the offer, a system solution, which consists of three modules. The first module is in contact with the Pre prepress or the Amplifier on. transfer of the strengthened signal is then wirelessly to the two, each with 50 watts (RMS) strong Class D amplifier equipped amplifier modules, in which the speaker cable is connected. Overall, therefore 100 watts RMS power for the PA available, that's enough also for medium-sized placement without difficulty. The name "Universal Wireless" it says - the flexibility is almost limitless. It can be any commercially available speaker with the system. Acoustically highly recommended because of the phonetic homogeneity of course products from their own home. Therefore, we have the compact, elegant KEF iQ50 stander with a unit price of comparatively narrow EUR 319 as a test sample to appoint, so that the entire chain a value of EUR 1,237 represents. We have in the test verified that KEF with this quote the great throw on a acoustically exciting wireless system succeeded.

Processing

Interesting design of the top


Precise friction chassis


Stand


Bi-wiring terminal of the iQ50


The material quality of the speaker grille cloth is not exceptionally well


The form tapers strongly to the rear


Elegant wireless receiver

Metal screw at the two receivers
All components are very clean process. The small wireless modules look very elegant, which means that even if they are visible for each frame, there are no visual problems. The black-and-high-gloss surface leaves also constitutes a solid impression as the rounded, curving forms. The iQ fallen 50 with accurate, uniform surface quality, Folierung of the body falls carefully. The corners are very well processed, the chassis is clean and with very small gap sizes fit. The base includes spikes leaves for this price class a very high-quality impression. This can be supplied by the speaker grilles are not necessarily argue. While they sit well, and the substance poses no wrinkles, but affects quality of the material rather average. That dropped us to bi-wire speaker cable connecting the two terminals at 50 iQ extremely well, and also the stable metal screw for LS Cable to the two wireless receiver modules will find our consent. Overall processing in relation to the price class: Excellent.

Technology and Equipment

The complete Universal Wireless System


Power of the Adapter


This power supply is located at 2x, one for each recipient

KEF offers with the Universal Wireless System consists of two receivers and a set of existing channels, which in its basic configuration for the sound in stereo is designed. The connection is simple: The transmitter is supplied via a cable to the Cinch-L/R the AV receiver, stereo amplifier or stereo / surround pre-connected. For surround configurations will be further universal wireless units, according to other pre-outs connected. At the receiver units in the 50-watt (RMS) Class D amplifiers are incorporated, then using ordinary speaker cables connected the passive boxes. Here you can also choose very short cables - the user is completely flexible. The Universal Wireless System is suitable for all commercially available passive speakers, but we have within the meaning of a "family sound" the KEF iQ to 50 ordered to check how the "KEF-Family" as a complete chain suggests. The volume is at Operating completely on the amplifier / receiver regulated.

iQ50

Woofer and bass reflex opening


UNI-Q chassis

Constructive main feature of the iQ 50, the lowest standing of the new iQ Series, the KEF's proprietary UNI-Q driver. In this design the tweeter sits in the midrange, which is a perfect Group Delay and a spatially accurate sound picture possible. Newly developed the "Tangerine wave" on the Aluminiumkalotte of the 19 mm tweeter has the task of the response throughout the room to improve. With a particularly powerful magnet system trumps of the Mid on. Another feature is the constructive Titaniumlayered cone. Fineness and a clearly accentuated the audible sound effects. The exceptionally high quality propulsion guarantee low distortion and provide the basis for the new, ultra-lightweight dual composite chassis bass dar. The consequences: A low THD, and a rich, sovereign bass. The newly developed crossovers are for a possible brief and thus pure signal directly to the terminals mounted inside This creates a closed sound image with soft, smooth transitions between the different parts of the spectrum. The specially curved housings are designed so that reflections on a minimum stay. At the same time the housing is extremely stiff, so are the aural harmony disturbing reduced to a minimum. he internal damping system is like a labyrinth, which is of standing waves removed.

Conclusion

The KEF wireless stereo set delivers extremely flexible deployment

This is one of the biggest surprises this year test: How confident are the KEF solution consisting of 2 x iQ 50 and wireless module, our honored as "outstanding" erspielt, we would have never expected. Through the clear, sovereign and adult sound, the KEF System test solution to this logo but bear with pride. The Universal Wireless solution excited by almost complete freedom noise, high level resistance and dynamic sound. Also, the quality of all components found processing our full consent. And even when it collects the KEF system smooth 10 of 10 stars because not even for 1.300 EUR is a superior wireless stereo solution that does not demonstrate real weaknesses are.
