I listen to my ls50 metas at tweeter level using 36” stands. I’m pretty tall. Read the setup instructions on the manual. It’s not intended that you aim the tweeters directly at you. Metas have better horizontal dispersion than originals. You have to just experiment and see what you think sounds best. Like any speaker setup.
Then I have my original ls50s on very low Isoacoustics stands just a few inches off the floor. That sounds good as well but different. High end more rolled off. YMMV.
