Here's the way I see it. Some people are afraid of this type of test because they're afraid they'll prefer the speaker that won the preference test in this video being the cheapest. Take for example the Dayton nd16 tweeter. $10 tweeter that can mate with speakers costing several hundred and fit right in as long as it's used in the bandwidth it's intended to play. I heard the mentioned Dayton tweeter mated with Audiofrog GB25's and Illusion 10" subs. And they were run by a McIntosh amp. I'm a firm believer that as long as you choose the right tool for the job you don't need to spend big money to get great sound. If you've been around the block with speakers ranging from a few dollars to hundreds of dollars and just spending a few dollars will get you the desired results, why spend more if you don't have to?
