Mark, We are going to sell this speaker product to European market when bundle with the 230V version of AC/AC adaptor.
Speaker bundle with AC/AC adaptor of 110/100V vresion will most likely be sold to US, Japan and other regions that requires this voltage. My main conern here is that should we accept the AC/AC adaptor compliance with EN60335-1 or request them to have it comply to EN60742 or EN60065 or EN60950 std.
