Sonus Faber Concerto replacement Speaker Grilles


Does anyone know where I can get a pair of replacement speaker grilles for my Sonus Faber Concerto speakers?
My stupid cat thought he could play with the material and has ruined them.
Any help would be appreciated in locating a replacement pair.

Sumiko USA parts department has kits.  It's a job, and it took me hours, but they look great.  For my Elipsas the kit is U$80.
Probably no longer available, but there are a number of companies that will recover your existing grilles.
