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.
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.
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 The phase plug has been replaced by a dust cap of identical shape and size to prevent air leaks.
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.
BOOKSHELF AND CENTER CHANNEL WOOFER
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.
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.
FILTERS AND INSIDE CABLES
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.
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.
