I have had the same setup with all my speakers. Carpet over wood floor, cinder blocks on the carpet, tiptoes under the speakers (pointy side to the cinder blocks). Works great, and the tweeters are the perfect height. Remember, you want the tweeters at about ear level from your listening position.
If my speakers were taller, I'd use paving stones instead of the cinder blocks.
Good speaker stands also have a way of decoupling the speaker from the stand.
