bookshelf speakers


I know that bookshelf speakers are not meant to be actually placed in a bookshelf, but I can I do? I only have room for a pair in a long bookshelf. It is actually more a ear level (sitting) bar with some books on it. No room for stands. I would like some help from you guys to shortlist a few speakers that would serve my needs. Again, the place for the speakers is a shelf about 50cm wide and therefore there is some room for a placement away from the wall. There are not other shelves on top of it. All suggestions are welcome. At this point I still don't have an expected budget, which I will define as soon as I have shortlisted the speakers.

Thanks for your help.

NHT Classic 3. Small, dense, 3way, inexpensive these days. well built and sound great.
The Wilson Duette's are specifically made to be placed right up against a rear wall / housed in a cabinet or on a bookshelf. If in the future you want to move them out into the room, all you have to do is change the supplied external resister and change over to the supplied grey cable versus the tan cable and you're set to go.
How deep are the shelves? I'd say either the Silverline Minuets for something on the shallow side and Silverline Minuet Supreme Plus is you have the space.

The little Minuets sound very good on shelves and play well with a broad range of equipment.
I went to a guys house who had Joseph Audio RM7 XL's actually in a bookshelf. Surrounded by...books. He was driving them with Simaudio gear and they sounded great to me. I'm not the most critical listener but I thought they sounded great.
