I have said this before, and the audiophiles will snicker in contempt, but I must say that there is NO SUCH THING as a speaker UPGRADE. It's all lateral, my comparison comments above notwithstanding. Speakers are all, not only different, but subject to biased ears/brain links. I don't care if they are made of concrete and are completely inert or are open baffle, cheap or expensive, or measure any which way but loose. They are just DIFFERENT, not better or worse. It's all in what you prefer. They are so subjective and there are so many variables in the delivery of sound to the listener in his/her listening space that any talk of loudspeakers being "in a different league" or "an upgrade" is really irrelevant to reality. (Cabinet quality, or speaker aesthetics would be an exception to the rule.
