Focal Volkswagen 2-Way Component Speaker Kit IS-VW-155

Focal Integration IS VW 155

The IS VW 155 2-way component kit is designed for drivers who want to replace their original audio system with a hi-fi quality sound solution.
The speaker drivers employ Polyglass technology, which delivers well-defined midrange and bass. The sound is natural, without coloration. The Aluminium inverted dome tweeter, a Focal technology, provides perfect treble reproduction in every direction. In addition, tweeter mounting foams and anti-vibration foams are included for a perfect set up.

The Focal IS-VW155 component speaker kit is Quick and easy to install.  This kit is compatible with the latest Volkswagen models (Passat, Tiguan, Golf 8, etc.), and can also be installed in many Seat and Skoda models.

Note: The Focal IS-VW155 kit is designed for vehicles that have tweeter slots.

Polyglass  Cone Technology

Polyglass technology, exclusive to Focal, consists in applying molten glass microballs on a cellulose pulp cone. This process combines an excellent paper damping with glass rigidity. The rigidity index exceeds even that of a single skin Kevlar^® and is almost ten times superior to one of polypropylene.

The mass/rigidity/damping ratio adjustment results in outstanding linearity of the frequency response curve, all from the inherent design of the cone. This innovation also greatly increases definition in the midrange.

Aluminium Inverted Dome Tweeter

Focal brand’s signature product, the inverted dome tweeter has been continually developed ever since it was created. It bears repeating that its main advantage, apart from its very low directivity, lies in its use of a coil of small diameter (hence very light and better accelerating) directly fixed to the rigid dome.

Just as with the cones of its bass and midrange speaker drivers, what makes Focal unique is working directly on the sound output and, therefore, on the mechanical characteristics of materials. When we introduced the pure Beryllium inverted dome tweeter ten or so years ago, we clearly demonstrated the decisive advantage of this exclusive technology.

Poron Suspension For Soft Treble

For the TNF tweeter, we have brought two major evolutions to our aluminum /magnesium tweeter. The suspension between the dome and its bracket uses Poron, a material with shape memory.

This suspension method is directly derived from the famous Utopia Beryllium tweeter, making it possible to reduce distortion by a factor of three in the 2-3kHz range, where the human ear has very great sensitivity.

Optimised Spatialisation

The inverted dome’s spatial characteristics and very low directivity already make it greatly superior to the conventional domes used by our competitors and to further improve this a wave guide has been developed. In a horizontal plane, its frequency response has a variance of +/-0.5dB. This performance guarantees an incredibly stable sound stage which makes the listening position much less critical.

It is due to more than twenty years dogged work on our manufacturing processes that it is possible to achieve such precision in a component as delicate as a tweeter.

Control over production is the one and only solution for continued innovation when it comes to loudspeakers...
