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?
A lot of the really high end speakers will have those build in. https://www.mcintoshlabs.com/products/speakers/XRT21K
The cone size isn’t directly proportional to the frequencies that it can produce. Since most audio companies try to use common parts for better pricing/margins they will gravitate to common sizes. That is mainly because that is what is manufactured. The difference between a 1” tweeter and a 1.35” tweeter is super minor because they can pitch produce the same frequency range. But a 1” tweeter will cost less than a 1.35” because 1.35 isn’t used anywhere.
