Sorry for the delayed reply, but I needed to verify something first before providing you the information.
The DM6SE has stainless steel part (part of the bracket).
Over time stainless steel can be affected by choline and can even break.
During this ISE (2020) we introduced 5 new FreeSpace FS loudspeaker and in these loudspeaker no stainless steel is used. For swimming pool areas we advise to use the aluminium grills as the original grill can be affected (cosmetic) by the choline.

Adding to what Arno stated, At ISE (2020) we introduced 5 new FreeSpace FS loudspeaker and these loudspeakers contain no stainless steel. For swimming pool areas we advise to use outdoor models of FreeSpace FS with the optional aluminum grilles as the original grill can be affected (cosmetic) by the environment. The hardware used to attach surface brackets to the structure also have to avoid stainless steel materials and adhere to any national or local building codes and follow safe installation practices.
