Raised Towers

It is not a dumb idea… and there are speakers out there you would enjoy more, like @russ69 said.

Of course I do because I often imagine bad things happening before I act. Maybe this is a silly habit of mine

Dino Game

I admit to putting Martin Logan SL3 electrostatics (&10" woof) on wooden dining room chairs, exactly where they normally sat on the carpet. Everything up 20".

Of course this was only during semi-free-for-all at-home parties we threw in my thirty's.  Otherwise I was civilized and sat down, along with the speakers...

Same history as above; planars for a long time, then good dynamic boxes, then great boxes. I also feel, adding up everything, they provides the least compromise.

I have a pair of older Genesis Genre I in a secondary system.  They are sloped back, which should tip the soundstage up but I always felt the images were lower than natural.  I put them on cinder blocks in my previous apartment and this did improve the sound in my opinion. I didn't import those cinder blocks to my new place so the Genesis speakers now sit on the floor and sometimes I'm keenly aware of they'd sound better if I put them back up on blocks.  So, it can be beneficial in some circumstances.
