Delta 模型是該公司研究該系列的起點。這款揚聲器是精心設計的科技瑰寶，也是 TRIANGLE 聲學專業知識的象徵。
Delta Signature 是在 Triangle 位於法國 Soissons 的車間製造和組裝的，是一款配備 4 個驅動器的 3 路落地式揚聲器，可提供細膩精緻的聲音。

箱體頂部有一個半吊艙安裝號角高音揚聲器、一個用於自然再現人聲的 16 厘米（6.5 英寸）紙中音和兩個 16 厘米（6.5 英寸）低音揚聲器。每個低音揚聲器由不同的機櫃外殼隔開。低音喇叭後波由三角專利技術的單雙排氣口排出。

Signature Delta 將吸引任何尋求高性能、平衡性和音樂性揚聲器的高保真愛好者。它是 15 至 40 平方米房間的完美選擇。

The Delta model was the company’s starting point in terms of research for this range. This speaker is a well-designed technological gem and a symbol of TRIANGLE’s acoustic expertise.
Built and assembled in Triangle’s workshop located in Soissons, France, the Delta Signature is a 3-way floorstanding speaker equipped with 4 drivers for a detailed and refined sound.

On the top of the cabinet sits a semi pod-mounted horn loaded tweeter, one 16 cm (6,5 inches) paper midrange for naturel reproduction of vocals and two 16 cm (6,5 inches) woofers. Each woofer is separate by a different cabinet enclosure. The woofer rear wave is discharged by a single twin-vent, a Triangle patent technology.

The Signature Delta will appeal to any High-Fidelity lovers looking for a high-performance, well balanced and musical loudspeaker. It is a perfect choice for rooms between 15 and 40 m2.
