Signature Technology

30 years Research and Innovations

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.


Driver in die-cast aluminum

The new phase plug has been designed to go with the 25 mm titanium dome. The tweeter horn is made from 100% injected aluminum originally developed for the Magellan project. The tweeter’s larger surface offers a greater dispersion of high frequencies. The compression volume of the back chamber has been significantly increased to provide better shock absorbance, thus preventing the return of sound waves within the dome.

These enhancements have improved the quality and detail of high frequencies, finesse and transparency, as well as minimal sound distortion.


Paper cone driver offering clear sound

The 185 mm aluminum basket has been entirely redesigned to provide better ventilation to its double-layered coil. It is equipped with a small pleat and peripheral short travel suspension. The new version of this treated paper cone provides increased clarity at this critically important frequency level of sound reproduction. The phase plug has been replaced by a dust cap of identical shape and size to prevent air leaks.


Double ferrites for precise bass performance

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. The cone profile was developed to be purely used in low frequencies. To make it more rigid, the glass fiber membrane is supported by a second paper membrane.

WOOFER (Bookshelf and Center Channel)


Specifically designed for this range, with the objective of creating a bass unit capable of reproducing low frequencies without a large volume load, while maintaining linearity in the high frequencies. It uses the same aluminum basket and treated paper cone to achieve the perfect tonal balance. The dust cap shaped as a phase plug reduces power surges and prevents any agressive sounds.


High Quality copper Alloy

Each model is equipped with a terminal for bi-wiring or biamplification. The terminals are designed and assembled by TRIANGLE. Made of high quality copper alloy they provide an excellent conductivity. They accommodate a 5 mm diameter cable and banana plugs with a locking system for excellent security.


solid bass

A unique element to the Twin Vent is that it discharges the rear wave created by the two separated bass drivers through a single vent. This system means that each of the drivers can operate in complete isolation. Increasing the volume 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 a dynamic, solid, well sustained bass.


High quality components

The performance optimization of each loudspeaker has enabled TRIANGLE to reduce the amount of components needed 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 the finesse of the midrange/high frequencies. As with all Triangle speakers they are protected against power surges.

To achieve the most optimized results the internal cable was only chosen after multiple listening tests. An element that is often forgotten, Triangle has always paid particular attention to the wiring. The cable provides a perfectly clear sound through medium frequencies and a solid, rigorous sound through low frequencies.

The combination of these two cables minimizes resonance and enhances performance. A special form of insulation, made from polyethylene dielectric, helps to create a cleaner and smoother sound. In addition, the PVC-jacket on the outside, maintains a low friction coefficient.
