Welcome to our in-depth Triangle - Quatuor 40th Anniversary (Magellan Series) - Floorstanding Speakers Review. From the very first note, these floorstanders deliver music as if you were seated centre-stage at an opera house—an immersive sound image that redefines what high-end audio can achieve. Whether you’re a discerning audiophile chasing every last detail or a music enthusiast craving visceral impact, the Quatuor 40th Anniversary is engineered to astound.

A Stage-Like Sound Image

At 135 cm tall, the Quatuor 40th Anniversary is a true three-way flagship. Its groundbreaking DPS II (Dynamic Pulse System) harnesses symmetrical bipolar radiation by integrating a rear-facing magnesium-alloy dome tweeter alongside the forward-radiating horn tweeter. The result is a stable, wide-open sound field that dissolves typical placement constraints—you’ll enjoy balanced bass extension even when speakers are positioned close to boundary walls.

Precision Treble and Midrange

The newly developed TZ2900PM-MG tweeter employs a next-generation magnesium dome and optimised horn profile to linearise frequency response and tame off-axis anomalies. A phase plug and counter-cap minimise rear-wave reflections, ensuring distortion is vanishingly low. Meanwhile, Triangle’s signature 16 cm paper midrange with micro-pleat suspension creates seamless transitions—vocals and strings emerge with astonishing neutrality, free of harshness or coloration.

Bass Authority and Dynamics

Three 16 cm woofers featuring an SVA (Sandwich Vibration Absorption) diaphragm and LHS2 heat-sink design handle powerful low frequencies with finesse. Fibreglass-cellulose sandwich cones combine rigidity and damping, delivering fast, controlled bass that’s equally at home with delicate chamber music or modern electronic rhythms. With power handling rated up to 260 W and recommended amplification from 80 to 500 W, these speakers thrive on dynamic peaks without strain.

Craftsmanship and Cabinet Design

Triangle’s Magellan 40th cabinetry is a masterclass in mechanical engineering. Curved HDF panels, moulded under tension, eliminate parallel surfaces and standing waves. Laser-measured reinforcements target micro-deformations, ensuring absolute rigidity and zero unwanted resonance. The “Wide-Venting” bass-reflex ports feature bell-shaped adapters inspired by aerodynamic design, producing a whisper-quiet laminar airflow.

Gold-plated, pure-copper bi-wire/biamplification terminals are housed in an 11 mm solid-aluminium plate, underscoring the Quatuor’s exclusivity. Each serialised terminal block speaks to the bespoke nature of this 40th Anniversary edition.

Innovative Crossover and Thermal Management

Crossover filters employ steep 24 dB/octave slopes matched to each transducer’s natural roll-off for coherent phase alignment and impulse accuracy. High-quality SCR-Audio French MKP capacitors, low-induction ceramic resistors and large-section air-core coils ensure ultra-low loss. The die-cast aluminium baskets double as heat sinks, with LHS2 rings channeling thermal energy away from the voice coil—maintaining linear performance during marathon listening sessions.
