Triangle - Duetto 40th Anniversary (Mangellan Series) - Bookshelf Speakers

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, optimises 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.

Features

• High-Fidelity Passive Speaker
• Rooms from 15 to 40m²
• Magnesium Horn Tweeter
• 16cm (6") Midwoofer
• Power Handling 120 W
• Recommended Amp Power: 30 - 200 Watts (8ohms)

 

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 centre 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 linearised.

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.

CROSSOVERS & COMPONENTS

The Magellan 40th crossovers are assembled in our production facility and use only high-quality audio components selected after many hours of listening:

• French MKP capacitors developed in collaboration with SCR Audio.
• Ceramics resistors with low induction effect.
• Large section air core coils.

These new components provide this 40th anniversary edition a very high definition over the entire sound spectrum The particularity of the crossovers in the Magellan range lies in the use of very steep cut-off slopes (up to 24dB/Octave), correlated with the natural cut-off slopes of the loudspeaker’s transducers, thus guaranteeing excellent phase response.

The crossovers used reduce the risk of delays. The loudspeakers’ natural frequency responses were modified digitally for a perfect match with its crossover’s transfer function. Furthermore, the drivers’ impedances were linearised so they act as a pure resistance, reducing the amplifier’s workload.

HEAT DISSIPATION SYSTEM

All the drivers in the range have a high rigidity die-cast aluminium basket allowing maximum clearance of the radiating rear surface of the diaphragm.

This basket is in two parts, the rear part acting as a cooling cover. These drivers are equipped with a heat transmission ring to optimise the heat transfer towards the outer cover (LHS2 system).

This ring collects heat dissipated from the core and the yoke and brings it towards the outer cover. The power handling capacity for each speaker can thus exceed 200 W RMS. This system prevents the risk of overheating and ensures better speaker performance. As an example, a 20° change is measurable over 120 minutes, with a pink noise registered at 100 watts and filtered with high pass at 80Hz.

SOLID WOOD CABINET

The design of the enclosure is crucial to the sound quality, and the cabinets of the MAGELLAN 40th anniversary edition have been carefully designed to ensure full stability.

Made of successive layers of 3mm of HDF (High Density Fibreboard), the sides are moulded under tension for several weeks to obtain the desired shape without any compromise in terms of rigidity. The curved cabinet has been chosen for a reason: to limit the standing wave phenomenon by excluding any internal parallels.

The Magellan cabinets feature a specific architecture resulting from a thorough study of the vibrations and micro-deformations of the cabinetry. Measurements were made by laser accelerometers to highlight and model the deformation of the cabinets to place the reinforcements at the optimal places to ensure the best rigidity to the cabinet against the disturbances generated by the drivers. This process allowed to eliminate all the vibrations and to remove any sound coloration linked to the cabinet.

"WIDE-VENTING” CONCEPT

In a bass-reflex speaker, at high power levels, conventional tube vents tend to create airflow disturbances resulting in “breathing” noise.

To solve this problem, we designed internal and external bell-shaped adapters inspired by wind tunnel construction to ensure a constant laminar airflow. This controlled ventilation system reduces distortion, and the bass now has depth and power.

TERMINAL

To enhance the crossover of this 40th Edition, TRIANGLE had to offer a connection plate that would live up to the work done.

The terminal is manufactured in a block of aluminium, reaching a thickness of 11mm. The terminals are made of pure copper then gold plated for a perfect electrical conduction. It allows for bi-wiring and bi-amplification. On the floorstander models, the crossover is done on separate boards for the bass and the medium/high. To do this, you just need to remove the jumpers.

Note that the terminals are designed to accommodate a bare audio cable, or a cable mounted with banana plugs or forks.

The serial number on the terminal highlights the exclusive character of this exceptional product.

Specifications

• Find a model in the Magellan 40th range that suits your listening room: from 15 to 40m2: Duetto 40th, from 20 to 50m2: Cello 40th, > 30m2: Quatuor 40th

Amplifier & Power Handling

• Recommended Amplifier power : from 30 to 200 Watts (8 Ohms)
• Power Handling : 80W

* The power handling of a speaker is the average continuous power that the speaker can accept without damaging the drivers. You can use an amplifier more powerful than the permissible speaker power by limiting the volume to 70% of the maximum capacity. Conversely, an amplifier that is too underpowered will clip and create distortion, which can also damage the speakers if it is used beyond its capacity.

* The impedance of a speaker can be simplified as an electrical resistance. The lower is the impedance of the speaker, the more current the amplifier will have to deliver.

• - Nominal impedance is measured at a frequency of 1kHz
• -- Minimum impedance is measured at low frequencies.

TRIANGLE loudspeakers never fall below 3 Ohms, which means they can be used with almost all Hi-Fi and Home Cinema amplifiers.
