TRIANGLE SIGNATURE THETA

The Signature Theta is a 2-way bookshelf speaker designed for use on dedicated stands, featuring high-density cabinets from the Magellan series and a premium gloss finish that gives it a modern and elegant appearance. Despite its compact size, it impresses with clarity and depth in the low register, thanks to a 16 cm mid-woofer with half-roll paper suspension that brings instruments and human voices to life, while the horn-loaded tweeter, positioned on top of the cabinet, prevents unwanted resonances.

Ideal for medium-sized rooms between 15 and 30 m², the Signature Theta is aimed at music enthusiasts seeking a compact speaker that combines musicality, power, and speed, and it can also be used as a rear channel in high-end home theater systems. The design and construction of the Signature series are entirely carried out in France at TRIANGLE’s workshop in Soissons, with meticulous attention to detail and artisanal perfection.

The cabinets are built from seven high-density fiber panels for a total thickness of 21 mm, significantly reducing unwanted vibrations. To achieve a uniform “piano lacquer” finish, seven to ten layers of paint are applied, each carefully polished. Every driver has been completely redesigned: the mid-range uses a 185 mm aluminum basket with a double-layer coil and peripheral suspension, the woofer features a dual-magnet motor, double coil, and inverted half-roll rubber suspension, while the TZ2550 tweeter has a titanium dome and aluminum horn with an optimized compression chamber for even high-frequency dispersion, minimizing resonances and distortion.

The speaker also includes terminals for bi-wiring or bi-amplification made from high-conductivity copper alloy, capable of accommodating cables up to 5 mm in diameter and banana plugs with a locking system, ensuring signal security and stability. Reducing components in the crossover, careful selection of internal cables with polyethylene insulation and a low-friction PVC outer jacket, and the Twin Vent system, which vents rear bass waves through a single opening, all contribute to transparent and balanced reproduction, with deep, solid bass and detailed, natural mids and highs.

Each Signature Theta thus represents an example of luxury engineering and craftsmanship, designed to deliver an engaging, dynamic, and precise listening experience, faithfully reproducing every musical nuance and ensuring excellent performance even at high volumes.
