Caring for your musical instrument
The membrane of this speaker has been crafted from over 350-year resonance spruce using lutherie
techniques. It is glued and varnished with varnishes that do not perturb the vibration. It is important
to care for it like a musical instrument - which means it must not be installed near a source of
heat, i.e. not above a fireplace or woodburning stove, a radiator, nor behind a window in direct
sunlight.
Cleaning and maintenance
It is important to check the
humidity rate in the room.
We advise you to maintain a
minimum 40% humidity rate.
To clean it, we suggest using
a soft damp cloth if necessary.
Do not use cleaning products
(so as to keep the natural
satin-finish effect) and
definitely not detergents
(which may damage the
varnish). Be careful not to
knock it with any hard materials. While such impacts should not disturb the sound, they could easily
leave marks and it is virtually impossible to remove these marks.
