I remember Best Buy carried EOSONE speakers about two decades ago. They were made by Polk and were the first I had seen with rear firing metal dome tweeters. I was just getting into audio back then and really liked them. They were also very inexpensive.
There are some other makers that have done it too: Opera, Sonus Faber, Hansen, Vandersteen, Von Scheickerts, Snell, etc. Evidently it changes the timber using the reflecting sound behind the speaker for a more spatial effect. Some audiophiles turn up their noses, but I like the idea and think it offers a nice effect in most cases.
I do agree, Stayngs Lawrence Audios look amazing
