If tweeters are better suited to highs, small speakers to mids and large woofers to bass, why don’t we have an array of ten say ten or twenty gradually increasing speakers from tiny tweets to ENORMOUS woofers, each with a unique crossover at a specific frequency they perform best at?
We really seem to have settled on three sizes. Tweets, miss, and subs. Why is that the case?
Surely more speakers handling less varied frequencies means a better response, right?
You want to minimize the number of crossovers. So it’s a trade off between the bandwidth of the drivers and minimum number of crossover points. Two crossovers is a pretty good compromise.
