Product Description

Utopia M: The only limit is your creativity.

 

MAKING THE IMPOSSIBLE POSSIBLE
Focal has invested a lot in Utopia M and has excelled itself. Making the impossible possible, elevating sound excellence to a level never achieved before : this was the goal set by our engineers who developed, among other things, a brand new ‘M'-profile 'W' sandwich cone.

DESIGN AND PERFORMANCE
Handmade in our French Workshops, all the Utopia M speaker drivers use high-end codes: a unique cone profile and a unique chassis. The design of the Utopia M chassis is a subtle mix of tradition, performance and elegance.

TAILORED INSTALLATION
By choosing each speaker driver in the range based on your vehicle and your needs, you can build your own high-fidelity audiophile system. Tailored installation, ‘à la carte’, where the only limit is the creativity of the installers.

'M'-profile 'W' sandwich cone

 

The new, patented, ‘M'-profile cone is the result of many years of research and our expertise in materials and their geometry. The innovative ‘M’-profile, made from a single piece, means it is incredibly rigid and perfectly combines the three criteria essential for creating an “ideal” speaker driver: rigidity, lightness and damping. The result is an extremely linear frequency response, a low distortion rate and better sound dispersion.Upon listening, this cone delivers striking realism and level of detail, that transports you into the heart of music

TMD® surround
 
TMD® surround
 

Originally developed for the Sopra line of high-fidelity loudspeakers, our TMD® (Tuned Mass Damper) surround has a unique profile, designed to better control the effects of resonance and to drastically reduce the distortion associated with deformations of the cone. The speaker driver takes advantage of this patented technology by spreading better defined and very realistic midranges’ frequencies.

 

 

TMD - Tuned mass damper



The obsession with the midrange

 

The midrange register is no doubt the most complicated to control in a sound system. On one hand, there must be a smooth transition with the bass. On the other hand, it must be tuned to the tweeter in terms of dispersion and acceleration. This determines the homogeneity of the timbre and spatialisation.

For the past 20 years, we have been working on mastering the "break up" (the frequency at which the cone becomes deformed, leading to distortion) of our 3rd generation "W" cones and on drastically reducing the resonance of the tweeter with the IAL 2. Today, thanks to the power of finite element analysis, our teams have developed simulation software to visualise the dynamic behaviour of the suspension which connects the cone to the basket, thus revealing the performance issues requiring attention.

Tuned mass damper

Following the discovering of these issues, we had to conceive the equipment to solve them. The solutions already known for increasing the damping properties of the suspension all result in an increase of the mass which consequently alters definition. The answer came from a technology used in earthquake-resistant skyscrapers and which is also used for the suspension on racing cars! This technology is called a "Tuned Mass Damper": an additional mass oscillate in opposition to the resonance frequency to control it.

Applied to the speaker driver, the solution consists in simply two tubular rings on the suspension whose dimensions and position have been judiciously determined. They form our Tuned Mass Damper (TMD) and they stabilise the dynamic behaviour of the surround according to resonance, thus avoiding deformation of the cone without afflicting the dynamics. This innovation is patented.





 

Visual analogy of the surrounds

 

 

 

Our Tuned Mass Damper (TMD) consists of two tubular rings moulded onto the surround. On the left the default suspension, on the right, the TMD suspension. This simple solution, perfected thanks to our new software, stabilises the dynamic behaviour of the surround according to resonance, thus avoiding deformation of the cone without afflicting the dynamics.


 

Principle of the Tuned Mass Damper



 

The principle of the tuned harmonic damper (TMD): The graph on the left demonstrates the principle of the tuned mass damper. In red, an m1/k1 system with very pronounced resonance. By adding a mass/spring system m2/k2 (upper section of the diagram), there will be two resonance peaks, as represented by the blue curve. The drop or anti-resonance being previously based on the resonance of the main system, we get the green curve. Finally, by judiciously adding a damper, we obtain the purple curve. The resonance has almost disappeared!

With Sopra hi-fi speakers, we opted for exponentially shaped cones in order to increase frequency response, and consequently impulse response. Another reason for increasing definition.


 


Measurement and analysis


 

Improved response linearity between 1 and 2kHz and the frequency extension provided by the exponential cone profile..
Frequency response of our latest midrange driver (blue trace) compared to the previous-generation W-cone midrange, representing prior state-of-the art performance (red trace). Improvements to the magnetic circuit also contribute (see next section). NB: The dip at 3kHz in the blue trace is due to the tested driver not being fitted with a dust cap.
