TRIANGLE has decided to relocate part of its manufacturing process to France, with the view of producing top quality speakers utilizing the expertise and the experience of its local teams. This form of luxury craftsmanship combines the finest woodwork with TRIANGLE's acoustic expertise. Triangle's goal is to share the emotion of live performance, to realistically reproduce the sensation and realism of every instrument or voice. You don't just listen to a Triangle loudspeaker, you feel it.
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.
For many years now, TRIANGLE has been investing in the latest technology to constantly innovate and improve its acoustic expertise. A Klippel system is used to conceive and simulate loudspeakers. Modern prototyping tools such as 3D printers, the latest CAD software, as well as MLSSA and CLIO measuring systems, enable the company to put theory into practice. Many different types of tests help to define the best-adapted shapes and most suitable material to use.
A new phase plug has been designed to go with the 2mm titanium dome. The tweeter horn is 100% injected aluminum developed originally for the Magellan project. At present, Tweeter's larger surface offers a greater dispersion of high frequencies. The volume of compression of the tweeter's back chamber has also been increased to offer better shock absorbance, thereby preventing the return of sound waves on the dome. These enhancements have improved upon the quality of high frequencies in terms of detail, finesse and transparency, as well as minimal sound distortion.
The 185cm aluminum basket has been entirely redesigned to provide better ventilation to its double-layered coil. It is equipped with a small pleat, peripheral short travel suspension. The new version of its cone in treated paper offers increased clarity at this very important frequency section of sound reproduction. The phase plug has been replaced by a dust cap of identical shape and size to prevent air from escaping, as it would normally do so in an enclosed volume.
This driver benefits from numerous enhancements producing a faster and deeper bass. It is equipped with a double magnet motor, a double-layered coil and an inverted half-roll rubber suspension, all of which ensure a faster speaker response. Its fiberglass cone has been improved upon to offer extra speed. The entire central part is closed with an aluminum cover.
The bookshelf and center channel woofer is specially designed for these speakers. The main difficulty lay in the technical prowess to develop a bass unit able to reproduce low frequencies without requiring a large volume load and also maintain linearity in the high frequencies. As other SIGNATURE's models it uses the same aluminum basket and treated paper cone in order to get a perfect tonal balance. Its dust cap shaped as a phase plug reduces surges and prevents any sonic aggression without adding more of electronic components
Each model is equipped with a terminal for bi-wiring or bi-amplification. The terminals are designed and assembled by TRIANGLE. Built with High quality copper alloy they provide an excellent conductivity. They accommodate a 5 mm diameter cable and receive banana plugs with locking system for excellent security.
The unique element to the Twin Vent is that it discharges the rear wave created by the bass drivers through a single vent. This system means that each of the drivers can operate in complete isolation. Increasing the volume of the sound does not disrupt the tonal balance, the only remaining distortion limit is the driver mechanics. The results in terms of power handling are amazing. The listening experience offers dynamic, solid, well sustained bass.
The performance optimization of each loudspeaker has allowed TRIANGLE to use fewer components in its filters and audio signal path. As a result, the range benefits from greater transparency and a more refined tonal balance. The new filtering system, separating the bass section and the midrange/treble section on the Delta and Alpha models eliminates the emission of electromagnetic waves and improves upon the finesse of the midrange/high frequencies.
The internal cable (supplied by highly-regarded US manufacturer, Kimber Kable) was selected for its detail when it comes to the medium/high frequencies and for its steadiness in relation to the bass frequencies. The combination of these two cables, containing strands of different sections, minimizes resonance and enhances performance.
THETA is a compact bookshelf speaker, mounted on feet. The midrange clarity and the depth of the lower end register are impressive for a speaker of this size. Equipped by a 16-cm driver with a half roll suspension, the THETA offers amazing musical quality, as well as surprising power and speed for a bookshelf model.
