Helsinki


Only nature can provide materials that fully reflect the purity and simplicity of Helsinki’s Nordic design.

The fabric has been carefully woven by leading Danish textile designer Kvadrat. Specifically created to let sound pass perfectly through the woolen threads. The solid aluminum frame is molded in one piece to avoid any assembly marks or frail spots. And the leather strap has been carefully selected and crafted by Swedish leather manufacturer Tärnsjö Garveri.

Raw, pure materials chosen to fully reflect the essence of a Helsinki loudspeaker. Materials that will age beautifully.

Your Helsinki loudspeaker is simply built for a long-lasting relationship.

Because I'm happy


Your choices define who you are and how you want to be. Understated or outspoken. Rational or emotional. Talking about things to be done – or simply doing them.

A Helsinki loudspeaker is a matter of choosing an exclusive product, uniting Nordic elegance with craftsmanship. A product that will make you happy today - and years ahead. Because it has been built to last.

It’s so delightful to know you’ve chosen well.

Music on the move


A Helsinki loudspeaker is freedom of movement. A small, compact product including a powerful battery, a Bluetooth connection and a leather strap allowing you to bring your music along, wherever you go. And whomever you might be going with.

Life is a journey and you should make the most of it.

One thing is for sure: Your possessions should never weigh you down, only lift you up.

Petite, but powerful


The Helsinki loudspeaker gives you a grand sound. Surprisingly, perhaps, given it’s small size. But if you took a peak inside you would better understand how something so small can be so powerful. It’s the sound of experience.

So listen and enjoy.

Full Range

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.

Force Balanced Woofer

The Vifa Force Balanced Woofer incorporates two identical 60mm 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.

Digital Pure Path Amplifier

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.

Symmetric Passive Radiator

The Vifa Passive Radiator uses a 40mm x 70mm 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.
