Professional in-ear monitor

Our patented Twin Pulse scaled isobaric system becomes the drive unit of the new professional range of in-ear monitors.

When Andrea Ricci designed the first Twin Pulse, he had only one goal in mind: to build the best dynamic headphone in the world, and to achieve that, he had to tackle the greatest limitation of a dynamic headphone: the speed of transients. Everything about this in-ear is aimed at maximizing this aspect.

 

DISCOVER THE TECHNOLOGY OF SPIRIT TORINO

 

A powerful motor is the secret of our headphones

In an aluminum structure milled from a billet with high-precision CNC machines, the complex isobaric system of the Twin Pulse is recreated in miniature form.

 

For the first time, the isobaric dual-drive technique is applied to an in-ear monitor to obtain a motor unit with an exceptional performance package in terms of acceleration and control of the drive movement during the sound transient.

 

Twin Pulse offers playback linearity calibrated on isophonic Fletcher-Munson curves (with the same sensitivity as the human ear) and can therefore be used as a reference instrument to verify the timbral reliability of a recording.

 

Twin Pulse does not interpret the sound but reproduces it faithfully. Therefore, it is important to select the components of the audio chain so that its transparency and dynamics can be optimally utilized.

Spirit Torino interprets the design of in-ear monitors with fundamental design cornerstones to achieve a performance level comparable to our best traditional headphone systems.

 

 

A MECHANICALLY COMPLEX SOLUTION INSTEAD OF A COMPLICATED ACOUSTIC DESIGN

In the Beryllium Twin Pulse IEM, you will find only a single high-quality driver that consistently covers the entire audio range and offers you a naturalness rare for this type of product. 

The Twin Pulse Motor Assembly consists of two identical 10mm micro drivers with powerful neodymium magnets and beryllium-treated diaphragms that work synchronously across the entire audio range, thus eliminating typical microacoustic problems and dangerous phase interferences.

 

 

A STRATEGIC CHOICE TO ENSURE NATURALNESS AND EFFICIENCY

One of the acoustic advantages of our broadband in-ear monitor system over a multi-way system is the absence of a crossover filter.

This type of filter is responsible for directing the part of the audio range within its scope to the individual speakers and is heavily influenced by the quality of its components. Furthermore, crossovers create complex overlaps of the same sound reproduced by different speakers, which our brain interprets as reproduced sound rather than the sound of an actual event.
 

AERODYNAMICS EMBEDDED IN AN INERTIA FRAME

Our inertia frame concept adapts to the world of in-ear monitors by optimizing the aerodynamics of the airflows that guide sound to our ears.

The design of the Sound Extractor has been optimized to minimize aerodynamic turbulence caused by the piston movement of the speaker's moving unit. 

The frame of the new Beryllium Twin Pulse IEMs has been calibrated to have high resistance to dynamic stresses and sufficient mass to meet the requirements of an inertia frame.

 

The anti-resonance treatment of the inertia frame is carried out by a series of Texalium composite inserts. 

 

The ventilated pad, which has always characterized Andrea Ricci's acoustic designs, evolves into the Micro Ventilation Pad System.

To calibrate the complex interaction of the pressures generated in the acoustic chambers of the Twin Pulse system, it was necessary to completely redesign the micro frame to ensure the dissipation of the additional pressure when inserting the in-ear monitor into the ear.

 

With the Micro VPS, you can select different sound signatures as needed by changing the front filter.
 

In the enclosed metal stand, you will find three types of filters, marked with the color gray for linear studio playback, red for playback with +3dB in the lower range, and black for playback with -3dB in the lower range.
