What about the sun on black lacquer finish like on JL audio fathom subs and revel ultima series speakers?
The sun could only potentially hit the back and sides of the speakers, the fronts have the grill and face into the room, and the sun comes from behind so the grilles and drivers are not in any direct sun.
i do cover with sheets, but I wonder how much UV gets right thru sheets?
(I remember reading that UV goes right thru T-shirts)
Anyonr know of a sheet or cover made to filter UV fully?
