With its fast, expressive midrange and three-dimensional soundstage, the Triangle Magellan Quatuor 40th turns vocals and orchestras into vivid, tactile events. Its six-driver design marries silky treble, tight, punchy bass and commanding dynamics, while the rear tweeter expands the room-filling image. A lavishly built flagship for larger spaces, it delivers warmth, speed and musical scale.
Pros
Exceptionally clear, smooth and fast midrange gives vocals natural presence and expressive detail.
Expansive, deeply layered soundstage creates convincing holographic scale and strong fill between the speakers.
Tight, dynamic bass and fast transient attack bring realistic body to percussion and acoustic instruments.
First-rate veneers, metalwork, cabinet construction and versatile bi-wire terminals reflect premium craftsmanship.
Cons
Its substantial bass output can overwhelm smaller rooms, making a larger listening space preferable.
Careful positioning is needed to balance bass weight, holographic imaging and center-image solidity.
Deepest sub-bass is less plentiful than some similarly sized rivals on 20–24Hz-heavy material.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 95/100
The Quatuor 40th is described as an exceptionally fast, expressive and immersive loudspeaker, led by a notably vivid midrange and unusually deep, layered presentation. Its character is more warm, smooth and enveloping than razor-edged, while its substantial bass output needs an appropriately sized room.
Bass
94/100
Reviewers describe the three-woofer bass system as tight, punchy, lusty and dynamically convincing, with realistic body on percussion and acoustic bass. Output is substantial enough to overawe smaller rooms, although one reviewer wanted more weight on the lowest 20–24Hz organ material and characterises it as favouring quality over sheer quantity.
Mid
96/100
The midrange is repeatedly presented as the speaker's defining strength: clear, detailed, smooth, fast and free of harshness. Vocals are said to be lithe, natural, forward and expressive, while the presentation brings unusual warmth, depth and tangible three-dimensional presence rather than ultra-sharp outlines.
Treble
94/100
The magnesium tweeter is praised for its smooth, silky and slightly warm presentation, with a sweetness that integrates closely with the midrange. Reviewers also hear openness extending into the upper frequencies, while the rear tweeter adds useful ambience and expansiveness.
Soundstage Imaging
96/100
Spatial performance is a major highlight. One reviewer calls the Quatuor an imaging and soundstage monster, with exceptionally complete fill between the cabinets and images extending beyond them; another finds its front-to-back depth and layering remarkable, even if the stage is not especially wide in every setup.
Dynamics
95/100
Reviews consistently emphasise speed, transient attack and an energetic, open delivery. Deep percussion is reported to have realistic body and quick leading edges, while the fast midrange and dynamic bass keep demanding music lively and involving.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
95/100
The cabinet, veneers, metalwork and terminals are described as beautifully finished and executed with first-rate handmade attention to detail. Reviewers also note the layered high-density-fibreboard construction, extensive bracing and chambering intended to minimise cabinet-induced distortion, alongside unusually versatile and secure bi-wire binding posts.
Value for Money
94/100
At roughly £14,000 per pair in the UK and around $20,000 per pair in the US, this is plainly a premium purchase. Even so, one reviewer explicitly calls it a value, arguing that it competes successfully with speakers in the $25,000–$35,000 range, while describing it as a worthy flagship with very few compromises.

Manufacturer's Description — Triangle
Premium Floorstanding Speaker - Magellan Quatuor 40th
Music as if you were at the opera. The sound image takes on a whole new dimension here, filling the space with sophistication. The Quatuor 40th, a 135cm high 3-way floorstander, is the flagship of the new MAGELLAN 40th anniversary edition.
With a new dome made of magnesium alloy, its horn tweeter reveals the finest details of your recordings smoothly and accurately. The Quatuor 40th is characterized by the addition of a rear tweeter that allows the speaker to radiate energy to the front and rear of the transmitting point. The sound level is better distributed, and the placement of the speaker simplified.
The 16cm driver with a paper diaphragm and small pleat suspensions, a distinctive feature of TRIANGLE speakers, reproduces any vocal register with great neutrality and without the slightest coloration.
The powerful and extensive bass of the three 16cm drivers is perfectly suited for modern music as well as for a prestigious string quartet or a cello suite. Its proprietary SVA diaphragm and its cooling system provide exceptional performances in the bass and sub-bass register.
Its extended bandwidth and its significant reserve of power make it possible to easily provide sound in rooms larger than 30m2.
DPS2 Dynamic Pulse System
On the Quatuor 40th anniversary model, the addition of a rear tweeter that allows the speaker to radiate energy to the front and rear of the transmitting point, much like a symphony orchestra would. With this gain of energy initially lost off axis from the listening point, the sound volume is better distributed in front of the listener. This allows for easier placement of the speaker in the room and a stable and deep sound image with great openness without distorting the original signal.
SVA Membrane
The driver features a proprietary SVA diaphragm. This computer-modeled composite diaphragm is characterized by a ‘sandwich’ structure, composed of a double sheet of fiberglass with a cellulose pulp internal structure.
It provides the ideal combination of mass damping and rigidity to the moving coil. The driver thus handles strong impulses without distortion.
Solid wood cabinet
The cabinet of the MAGELLAN 40th anniversary edition has been carefully designed to ensure total reliability. The curved shape of the cabinet is made of successive layers of high-density fiberboard, each 3mm thick, thus excluding any internal parallels.
This cabinet is characterized by a specific architecture resulting from a thorough study of the vibrations and micro-deformations of the cabinetry. Reinforcements have been placed strategically to make sure the cabinets are rigid enough to withstand the powerful vibrations generated by the drivers at high volume levels.
