I’m not sure if anyone else can find it but awhile back someone posted pictures of DIY stands they made for their QS speakers. They really looked fantastic. So one option if you want to do a little woodworking you could make your own.

As jakewash says make sure what you use can hold their weight and is bottom weighted enough not to topple over.
