What I did was shopped the market to get a feel for actual value, read all the reviews of the speakers in my price range and then shopped used so I could get my money back if my ears didn't hear what everyone else did.
I learned that when a reviewer says a speaker needs 100 watts it usually means 500 watts and while measurements may show ports extend measured bass more often than not I can't hear it. Metal tweeters are much smoother than they were in the 90's...Stepping up my speaker game required me to step up my component game to really appreciate what was capable in home audio.
