OSLO

人目を惹くだけではありません
惹きつけて放さない卓越のデザイン

人目を惹くだけではありません


丸いシェイプの縁を視線が辿る・・・。

柔らかさ、内部のテクノロジーを注意深く覆うカバーをご覧ください。初めて Oslo に出会うとき、まずは目に触れられ、それから五感が開かれる。鮮やかな色、驚きのテクスチャー、表面の下になにかが隠れているのが伝わるセンセーション。前部にある刺繍付きの音量ボタンが囁く: これこそがスピーカーだ、と。近づき、探り、発見せずにはいられない。

目を閉じてこそ見えるもの


最近アメリカに旅行して、ボブ・ディランの『オリジナル・モノ・レコーディングス』を買いました。素晴らしい音質で、彼の最初の8枚のアルバムの完全収録版です。帰宅して、一晩じゅうリビングの床に座って、このビニール盤を聴きました。もう、それは・・・身体的な感覚を呼び覚ますような、優れたサウンドです。サウンドがあなたに触れ、鳥肌が立つ感じ。

レコードのサウンドは、他にはないものでした。実際、その場にいたかのように。コロンビア・スタジオで、ギターを持ったボブの目の前に。ほんとうに・・・ミュージックはいつだってこうでなくっちゃと思いました。真実だった、一音一音の輝きも逃さない、本物のサウンドでした。

完璧な印象


ソフトなテクスチャー。暖かいタッチ。Oslo の驚きの手触りの秘密は、そのウールカバーにあります。厳選した毛糸を Kvadrat がデザインした独特のパターンにていねいに織り上げています。

全工程を通じてリフレクションと直感を織り込み、Kvadrat が触覚における知識をサウンドの世界に翻訳しました。何十時間もかけ、荒い布、滑らかな布、ゴツゴツした布、シルキーな布見本の山に埋もれながら生まれたファブリックこそが、全体の製品エクスペリエンスのエッセンスとなっています。人目を惹き、耳をそばだたせ、指先を招きます。ウールは完璧な天然の素材。その心地よさと感触は、心を落ち着かせる、ベーシックな感触です。世界共通の素材。時を超える耐久力で、時を重ねるごとに美しく。

その職人技、耐久性と、製品と素材の生来のクオリティは、Oslo に少し触れてみれば分かります:感触こそがすべてです。

欠かせないもの


あなたがいちばん大切にするもの。日々の必需品から始まって、時間とともに愛着を増し、生涯肌身から離せない旅行のコンパニオンになります。なぜ?誰にも分かりません。ただ、気が付けば隣にあるのです。そうして、ホッとするのです。

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 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.

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 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.
