Because music is a series of accelerations only high efficiency drivers equipped with light cones are able to move quickly enough air molecules and thus provide intact timbres and respect the attacks of instruments.   >

-   Wide range units

Knowing that it is very difficult to achieve simple designed crossovers that point between 100 Hz and 5 KHz our constraint is then to choose drive units capable of covering bandwidth over these frequencies to which the human ear is very sensitive.
Moreover it is nearly impossible to achieve a three way crossover without generating phase splitting that it be electronic or mechanic.   

-Paper cones

Paper which has been the first material used for driver cones is the only one whose characteristics is that sound goes through it at the same speed than air .Group dispersion is thus respected and phase splitting are avoided which again the human ear is very sensitive to.

-Not altering the signal    

Using components to only point frequencies ,and not to rectify artificially flawed response, avoids disturbing the signal by a series of components whose the 10% tolerance varies according to the heat of the driver and of the crossover itself which in the end causes unsteadiness that alters and spoils sound reproduction.
We have then selected high efficiency wide range speakers which are made under schedule of conditions by a company that has manufactured these kinds of products for about 60 years now
As far as enclosures are concerned we have selected the Berthommé manufacture that has been making cabinets for famous brands for 30 years.
It thus guarantees the lifetime of our products.
