What is the difference between a 2.5 way, and 3 way speaker? Looking at the Paradigm Studio series. The 60 is a 2.5 way, and the 100, is a 3 way. Anyone owned a 2.5 way, and gone to a 3 way? Or vise versa?Notice any change the sound quality? Have less midrange with 2.5 way? New ht guy. Hope you can help.
