Luxury craftsmanship

The range’s conception, and design was 100% implemented in France at TRIANGLE’s workshop in Soissons. Thanks to the experience gained from the Magellan range, TRIANGLE is currently offering a form of luxury craftsmanship with SIGNATURE, born from the passion and the work of its teams.

Each item is made and assembled with uncompromised precision to strive for manufacturing perfection and irreproachable sound.

Technological Innovations

Over the years, TRIANGLE has developed and patented innovations, improving upon the mechanics and vibrations of loud speakers. Every driver has been entirely redesigned. A new 185mm (7.3") aluminum basket with better ventilation, new version of treated paper cones to increase clarity and top quality components to benefit from greater transparency and a more refined tonal balance. Other unique technology such as the twin vent and the SPEC system play their part in making TRIANGLE’s speakers unique.

Luxury woodwork

The Signature cabinets are made from 7 high-density fiberboards for an overall thickness of 21mm (0.8"). This high-density cabinet helps to considerably reduce the speaker’s vibratory behavior.

In view of embellishing this woodwork and of achieving a special luster, either seven or ten coats of paint are added during production in order to reach the “piano lacquer” finish. The cabinets are carefully polished to remove any flaws before adding a new layer of paint.

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 or 100 sqft).
