Designed to meet the needs of nearfield monitoring, these monitors combine an ingenuous design and numerous settings optimised for the acoustics of small listening rooms. Shape Twin stands out through its excellent rendering over the whole audio spectrum, its broad frequency response in the low end, and its high SPL considering its size. The compact design makes it easy to integrate even into the most cramped of rooms. Finally, its 2.5-way design gives it a real advantage when it comes to controlling the bass and lower mid-range registers which are the hardest to control in small rooms.
Shape Twin’s five innovations present a remarkable tonal balance, with very wide and precise stereo imaging. The low frequencies are well defined as well as controlled. The low-mid and mid ranges provide a true neutral sound. Focal Shape monitors provide remarkable acoustic transparency with new innovations that distinguish themselves through the wide and extremely precise stereo image.
Features
- Tweeter with very low directivity for a flexible listening position.
- Designed without a port, but with a double passive radiator, allowing it to be placed near a wall.
- Numerous settings for optimal integration.
- Accurate control, even in the very high end.
- Flax sandwich cone: controlled and well defined bass, natural and detailed lower mid-range and upper mid-range ranges.
- Mounting mechanisms present on the back and underneath the loudspeaker: for installing on a table stand, a microphone stand, the ceiling or a wall (mounting accessories not supplied).
FLAX SANDWICH CONE
THE UNIQUE QUALITIES OF FLAX
High Performance
F cones are made of high-quality flax fibers core enclosed by two thin layers of glass fiber. They satisfy the key criteria of a high performance diaphragm : high internal damping, high velocity of sound and high flexural rigidity.
Rigidity
All these criteria cannot be met by a mono-material cone. Sandwich technology greatly influences the neutrality of the sound produced by the cone, something, which has always been Focal’s hallmark. The expertise gained from the sandwich technology of the Utopia and K2 Power ranges enabled Focal to develop a revolutionary flax-fiber cone conciliating the 3 criteria.
Lightness
Flax is twice as light as fiberglass, because the fiber is hollow. It also has very low elasticity which makes it ideal to increase the flexural rigidity of a sandwich structure. Moreover, it can be obtained in non-woven bundles of considerable diameter and it can therefore produce the thickness required for a sandwich.
Internal damping
Composite materials have properties suitable for applications where both rigidity and low mass are required. However, their disadvantage is that they lack damping, which leads to very poor control of vibrations. Recent developments in this field combining composites and natural fibers have brought unexpected opportunities. Flax fiber has an excellent internal damping of the same order of magnitude as the glass or Kevlar® fibers or aluminum.
TMD - TUNED MASS DAMPER SURROUND
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.
NIC - NEUTRAL INDUCTANCE
The precision and detail of audio reproduction depend on the stability of the magnetic field.
STABILISING THE MAGNETIC FIELD
After having pushed back the limits in electromagnetic technology, our teams discovered the fact that beyond the magnetic field intensity and its homogeneity within the gap, there was a dynamic aspect we had no control over.
The magnetic field is not stable because it is modulated by three factors
- the movement of the voice coil (Lenz's law)
- the current passing through it (Foucault current)
- the frequency
Consequently, the voice coil, and all the moving part including the cone, is in the magnetic field which becomes too variable, and this leads to loss of precision.
NEUTRAL INDUCTANCE CIRCUIT TECHNOLOGY
After three years of research and the development of simulation software which makes it possible to visualise these complex interactions, Focal engineers created an incredibly stable magnetic circuit for the Sopra line.
The solution, NIC technology, lies in a Faraday ring whose dimensions, materials and positioning were optimised to make the magnetic field no longer affected by the position of the voice coil, by the amperage or the frequency of the current passing through it.
