The Theater 4's are a great all around speaker but remmember they are not Waynes most expensive design and in fact they are closer to the least expensive design. If you have a 300B amp I would suggest you think more along the lines of the stage 4's or the premium series. An amp like that will rise to the quality of the higher priced designs. And the Stage and Premium are smaller and more compact. I would say regarding the music that the seamless blending of the premium drivers are better served for classical music in general.
