Imcloud, these types of items are basically pieces of furniture, since they are so large and visible. I think buying someone a home theater as a gift is a great idea, but I wouldn't want to spring it as a surprise on anyone, as you would basically be decorating their homes for them. If I wanted to give home audio or video items to someone as a gift, I would make absolutely sure they are a hundred percent cool with the item's appearance, and have them know what to expect in size.
With that being said, one approach you might take is just go 2.0 for now, and get some solid bookshelf speakers that look so nice she couldn't possibly object to them. One advantage to that approach is some sturdy good looking speakers could last a long time (barring abuse), and so it would be something that brings great returns. Some fancier speakers might also compel the recipient to take greater care for them than something which wouldn't seem to be as higher-end, in appearance at least- 'pride of ownership' and all that. Some suggestions I would make in that vein that is within your budget:
KEF Q300
Aperion Verus Grande
Swan D2.1se + stand
NHT Classic Two
You might also try one of
these kits from parts express, there are some very lovely speakers in there, they will likely perform above their price point, they are easy to assemble, and the fact that you put them together may engender a greater affection for the gift from the recipient. Check
this one out, it is heavy-duty and gorgeous. Take a look at
this one too, very tasteful speaker that will also be a terrific performer. Watch the little videos embedded at the product pages to see how easy it is to assemble those speakers, you could have it done within a half hour, and all you need are basic tools, like a screw driver and hammer. I haven't put together one myself, but it really looks like a piece of cake.
