Triangle Magellan- Duetto 40th
Premium Bookshelf Speaker - Magellan Duetto 40th
Liveliness and dynamics are trademarks of TRIANGLE’s sound, and they are packed into this gem, the Duetto, a compact 2-way bookshelf speaker.
Superb piece of engineering, its horn-loaded tweeter TZ2900 is equipped with a next generation dome in magnesium alloy. This transducer highlights the finest details of your recordings and brings out the subtlety of the upper harmonics.
Its full-range 16 cm midrange/bass driver produces rich bass details. It features a new paper cone that reproduces any vocal register with great neutrality without the slightest coloration. The Duetto speaker offers a really clear sound and puts the music forward.
Its elaborate crossover, equipped with high quality components, optimizes the bass and treble phasing for an outstanding transparency.
This compact speaker fits perfectly in rooms of less than 30m2, a technological achievement for a speaker consisting of only two drivers, The Duetto is supplied with an accessory box for an adapted decoupling. The S08 speaker stand, designed specifically for this model, is available as an option.
Speaker stands: S08
Designed for the MAGELLAN Duetto 40th, these top-of-the-range stands incorporate a locking system that ensures the speaker is held securely in place. Positioning your speakers perfectly at ear level, the S08 ensure excellent sound reproduction. With their high stability, the stands absorb unwanted vibrations, thus preserving the neutrality and sound precision of your speakers.
The S08 have watertight tubes in which you can add granular sand or tiny steel balls to ballast the foot and increase stability. The stand is decoupled by three metal spikes, which are easily adjusted from the top. The center spike features SPEC technology for optimal vibration dissipation.
A cable management system at the back of the stand hides cables for a harmonious integration of your system in your living space.
TZ2900PM-MG tweeter with a magnesium alloy dome
A major innovation of this 40th anniversary edition, the TZ2900PM tweeter is equipped with a next generation dome in magnesium alloy providing a significant improvement in terms of linearity and consistency.
Its horn is shaped to limit directivity, i.e., off-axis drop in high frequency level. Together with the phase plug, this pairing allows the frequency response to be linearized.
We also added a counter-cap to the motor to reduce rear waves reflections, limit distortion and control the upper end of the sound spectrum. The TZ2900PM-MG tweeter provides an exceptionally smooth and fluid musical quality whilst ensuring accurate sound reproduction.
Midrange/bass driver with a paper diaphragm
With a cellulose pulp diaphragm and its “progressive” suspension, the midrange/bass driver has that rich, natural sound the brand is known for. Thanks to its suspension, there is no clear separation at the cone attachment, resulting in a seamless mid-range. The diaphragm houses an ultra-light anti-vortex polypropylene cone covered with a latex damping material to limit end of band irregularities.
Featuring a powerful motor and a perfectly matched voice coil, this driver is capable of reproducing firm and dynamic low frequencies while maintaining remarkable clarity and finesse in the vocal register.

- Bass extension is room- and placement-dependent; claimed low-frequency reach may need burn-in and wall placement to materialize.
Sound Quality
91/100
Bass
90/100
Multiple reviewers praised the low-end as surprisingly deep and tuneful for the speaker's size, with Tracking Angle calling the bass ‘satisfactory for all acoustic instruments’ and PT Audio noting greater bloom when moved closer to walls. Some reviewers noted the claimed 38Hz is optimistic in small rooms and placement/room and burn-in improve extension, so score is high but realistic for its size.
Mid
93/100
Consistently singled out as the speaker's strongest asset: Tracking Angle calls it a 'Master Class in Midrange' and PT Audio highlights seamless, clear, human vocal presentation. Multiple reviewers praised tone, microdynamics and lack of grain, supporting an exceptional midrange rating.
Treble
89/100
Horn-loaded magnesium-dome tweeter yields extended, detailed and smooth top end per PT Audio and Tracking Angle, with good air and detail. Some reviews (What Hi‑Fi, The Ear) caution it can sound forward or a touch bright with certain electronics before burn-in or careful partnering, so slightly capped below reference.
Soundstage Imaging
92/100
Reviewers regularly praised expansive, precise imaging and scale — The Ear and PT Audio note a large, stable soundstage and good instrument placement. Driver integration and wide sweet spot were repeatedly commended, supporting a very high score.
Dynamics
90/100
Described as punchy, agile and able to handle fast transients (What Hi‑Fi, The Ear), with reviewers noting engaging rhythmic drive and excellent macro/micro dynamics. Requires appropriate partnering to reach full dynamic potential, but performs strongly for the form factor.

Build Quality
93/100
Luxury finish and workmanship repeatedly praised: Shadow Zebrano veneer, flawless finishing and robust cabinet bracing (PT Audio, The Ear, Tracking Angle). High-quality crossover parts and alloy terminal plate are noted, justifying a top-tier build score.
Features Connectivity
83/100
Passive baseline applied (80) with +2 for bi‑wiring/bi‑amp capable, gold‑plated terminals and +1 for special aluminium terminal plate/engineered connectivity, yielding 83. Includes high-quality crossover components and robust terminals; no DSP/streaming penalty (passive speaker).
Value for Money
88/100
At roughly $7k–$7.5k/pair reviewers felt performance exceeded expectations for the price (PT Audio, Tracking Angle) though The Ear notes handmade French build commands a premium. Strong performance and finish justify the cost, but it isn't a bargain.
