I have a low ceiling in my basement 84" so I like the sound with the tweeters lower than ear level. I have 20" monitor speakers and 12" stands and also dedicated 16" stands and I prefer the lower stands much better. I also have them tilted up with old school Audioquest sorbothane dampers. I've also experimented with the speakers on the floor tilted up and I like that presentation as well. I think it all depends on the room but for me with the low ceiling, low stands sound better...
