Shape 50 is the versatile monitoring loudspeaker par excellence. This monitor can be used from 30″ away (80cm), and it has very extended low end frequency response (50Hz) considering its compact design. Thanks to this design and to the numerous settings, this monitor is ideal for rooms measuring less than 130ft2 (12m2).
The three monitors are all made in France and integrate five innovations to maximise acoustic transparency. Designed to meet the needs of nearfield monitoring, Shape monitors combine an ingenuous design and numerous settings optimised for the acoustics of small listening rooms.
These innovations provide remarkable acoustic transparency. These new work tools distinguish themselves through the wide and extremely precise stereo image. The bass register is articulated and controlled. The lower mid-range and mid-range benefit from extreme neutrality, and without any masking effects, making equalisation of these essential registers much easier. Finally, the new tweeter is what’s at the source of the very high definition. It efficiently reveals any hissing, and it’s also very precise in the very high end.
The Poron® suspension provides a more linear frequency response curve below 6kHz, improving crossover with the woofer.
The magnetic component has also been optimised thanks to a voice coil with a Kapton® frame which significantly reduces the Foucault current, and consequently, distortion.
Finally, the horn housing the tweeter has been designed to provide equal horizontal and vertical directivity.
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.
