All the magic of music unfolds in this compact 110cm high 3-way floorstander. The real achievement lies in the transfer of the performance of the MAGELLAN Grand Concert into a modestly sized speaker.

The TZ2900 horn tweeter features a next generation dome in magnesium alloy that enhances the finest details of your recordings. This transducer brings out all the details of the upper harmonics.

Specialised in the midrange frequency range, Triangle perpetuates its tradition with a 16cm driver with a paper diaphragm and small pleat suspensions, reproducing the vocal register with great neutrality and without the slightest coloration.

The sandwich technology developed by the aerospace industry ensures that the two bass drivers are extremely lightweight and at the same time also exceptionally rigid.

The Cello achieves a unique kind of intensity. The listening experience is pure unlimited pleasure regardless of the type of music, delivered with magnificent scale and it is never fatiguing. It has a wide array of musical skills. It is as perfectly at ease at high volume as it is for intimate listening and is suitable for rooms measuring 25 to 50 m2.

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.

WOOFER

TRIANGLE aimed to develop a speaker in the extreme low register with a relatively low distortion rate despite high listening levels.

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.

The motor, designed to reduce the total overvoltage coefficient, reaches extremely low frequencies. The specific profile of the polar parts combined with the quality of the metals allows the development of a powerful and homogeneous magnetic field, guaranteeing a linear movement of the coil.

The bass driver has a thermal transmitter covering the back of the cylinder head (LHS2). This heat sink allows an optimal heat transmission to the external structure of the driver, thus improving the power handling of the transducer.

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.

STAND AND SPEC SYSTEM

The SPEC system developed by TRIANGLE is the result of a research inspired by musical instruments such as the cello. This instrument has a resonance box vibrating at certain frequencies. To give it more support, the manufacturers have decided to connect it to the ground by a single point of connection, a part of the energy is thus directly led towards the ground.

TRIANGLE’s approach for the loudspeaker is the same. So, we decided to put three quarters of the speaker on a base. However, for the system to be highly efficient, it was necessary to insert an interface made of an inert polymer between the base and the cabinet. From then on, we could consider that the enclosure was almost completely isolated mechanically from the floor. We only had to capture a large part of the vibrations of the enclosure and its energy on the remaining front quarter and transfer it directly to the ground. This principle combined with the SPEC system eliminates any transmission to the ground.

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

Recommended Room Size

• The Cello 40th is recommended for listening rooms with an area between 15 and 50m2.
• 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 60 to 500 Watts (8 Ohms)
• Power Handling : 200W

* 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.
