Signature 系列的旗艦產品，這款 1.3 米高的落地式揚聲器展示了 TRIANGLE 聲學和技術知識的綜合。與每一款 Signature 產品一樣，Alpha 是在法國的 Soissons 工作室設計和手工製作的。

得益於 Magellan 的研發，Signature 揚聲器具有極高密度的箱體，可提供無與倫比的聲學體驗。所有機械方面都經過研究以提高整體性能。

Alpha 揚聲器集成了一個半吊艙安裝號角加載高音揚聲器、一個帶有小褶皺懸架的紙中音揚聲器和三個專為此型號設計的低音揚聲器。它擁有所有 Signature 技術，包括雙通風口，確保完全的低音揚聲器絕緣，從而獲得更好的聲音透明度。

Signature Alpha 是一款功能強大的揚聲器，具有深沉而快速的低音，主要推薦用於大房間（30 平方米以上）。

The flagship of the Signature range, this 1.3-meter-high floorstanding loudspeaker displays the synthesis of TRIANGLE acoustic and technological know-how. As with every Signature product, the Alpha has been designed and hand-crafted in France at the company’s Soissons workshop.

Benefiting from Magellan R&D, the Signature speaker features extremely high-density cabinets for an unmatched acoustic experience. All mechanical aspects have been studied to improve the overall performance.

The Alpha loudspeaker integrates a semi pod-mounted horn loaded tweeter, one paper midrange with small pleated suspensions and three woofers specifically designed for this model. It has all Signature technologies including a twin vent ensuring a complete woofer insulation for better sound transparency.

The Signature Alpha is a powerful speaker with deep and fast bass, it is mostly recommended for large room sizes (above 30m2).
