Hola. I had all three models, the Theater, the Stage and the Stage X. My ears are very happy with the Stage X, and the new folded motion tweeter is the clue. This incredible tweeter has about 8 inches of diaphragm surface, but weights less than one inch dome tweeter. Remember that moving the air is how the sound is produced. Bigger and faster diaphragms is the way to go. The coherence and the overall sound of the Stage X, its a shiny jewel to use in your system. When listening live concerts and the dialog of the movies are very easy to understand. I do recommended it to you. Its another forward step in the speaker's later. I do not listen any bad resonances or color the musical instruments...really, I do enjoy it very much! You can't go wrong with the Stage X. Happy listening!
