在最近一次去往美国的旅途中，我带上了Bob Dylan 独具匠心的原始单声道录音带。他的8部唱片在这张录音带上得到了完美的诠释，堪称完美音质的伟大杰作。当回到舒适的家，我整晚悠然地坐在客厅的地板上，惬意地用心聆听着天籁之音。那声音是绝无仅有的，可以感受到自然界的伟大之音。一种隆隆的声音直触灵魂深处。

The Vifa 50mm full range driver act as midrange and tweeter at the same time and thereby handles the frequency range from approx. 250Hz up to 18000Hz. Left and right channel full range drivers are spaced apart as much as possible and angled slightly backwards and to the sides to satisfy optimal performance at various listening heights and maximum stereo width. It sits in its own separate enclosure to avoid modulation from the woofers and for exact control of roll-off characteristics. The full range driver is designed with a rigid and light aluminum cone and dust cap with specially designed geometry for smooth and extended frequency response. A vented aluminum voice coil former ensures low moving mass and good cooling properties. A copper cap on the pole piece helps to reduced unwanted distortion and extends the frequency response. The powerful Neodymium magnet ensures high efficiency in a compact size. It all adds up to a very coherent and natural reproduction of the midrange and treble frequencies bringing out that authentic sound experience.
The Vifa Force Balanced Woofer incorporates two identical 65mm diameter custom made woofers mounted back to back. The Force Balanced Woofer is positioned in the speaker enclosure so that one woofer is radiating from the front side and the other is radiating from the rear side. Both woofers move in and out at the same time but due to the 180 degree opposite orientation, the mechanically induced vibrations that would normally be transferred to the enclosure are outbalanced by the opposite movement. The two woofers are mechanically fixed to each other – rear side against rear side – forming a very rigid and solid construction that forms a perfect platform for the woofer to start and stop with great precision and also to maintain the precise and undisturbed micro movements of the woofer. This enhances bass precision greatly and forms a very strong mechanical connection between front side and rear side of the speaker enclosure. This leads to lower coloration and lower mechanical vibration noise.
A great audio amplifier multiplies the input signal and provides the amplified signal to the drivers without lacking power or adding artifacts.
At Vifa we have a straightforward and simple strategy to designing amplifiers. We keep the signal in digital domain as much as we can, so it won’t be affected by noise. Next, we handle the digital signal just as gently as if we operated in an analog domain.
The amplification in our products is handled by switched (class-D) power amplifiers of the Digital Pure Path type. It has four powerful separate amplifier channels for maximum headroom and optimal performance. It conjoins with a high performance DSP (Digital Signal Processor) which completes the 100% digital signal chain and complements the product by having very low noise output, low distortion and a high dynamic range.
With this, we obtain the authentic sound that has become Vifa’s trademark.
The embedded battery makes it possible for you to enjoy your music literally everywhere.
Superior power capacity, lifetime and eco-friendliness are ensured by Vifa’s choice of Lithium-ion batteries from renowned brands very high quality level.
These batteries deliver high power instantaneously and keep the dynamics in the music you listen to.
The Vifa Passive Radiator uses a 45mm x 80mm flat rigid cone that moves with a resonance frequency determined by a precisely calculated weight/mass mounted in a soft linear long-throw suspension. This is to some extend comparable to using a bass port tube also referred to as a vented system. For a small enclosure, a vented system would require a long and narrow tube in order to obtain a resonance frequency low enough. This would take up a large portion of the limited volume inside the enclosure and also create loud noise as the air moves in and out of both ends of the narrow tube. The Passive Radiator takes up no space inside the cabinet and creates no noise. The Symmetric Passive Radiator design by Vifa uses two passive radiators mounted on opposite sides of the speaker cabinet at equal distances from the active Force Balanced Woofer. This outbalances the mechanical impact on the cabinet and ensures same work load on both woofers and both passive radiators. It all adds up to a very impressive bass reproduction from a physically small speaker.
