I didn't see a response as to why you couldn't put them on stands, so this may be of no help. It's a bit of an out of the box suggestion. Could you hang them? Let me explain. I don't remember where I got the idea, but I believe I read somewhere that any contact with another surface can cause vibration and resonance issues. This made sense to me since a lot of speakers are built with a plinth or some sort of stand to reduce the contact area and/or elevate the speaker. Sub stands and the use of sound deadening materials under speakers seems to get recommended alot. I had a small set of bookshelves set up in an auto shop. The speakers were really undersized for the room. We got some plant hangers and suspended them from the ceiling. The sound improvement was amazing. Alot of people that came into the shop commented on the great sound of these cheap little speakers. Maybe we just got lucky. It was the only time i've ever hung speakers, but it seemed to work. Just a thought.
