. I want to begin using 3-way speakers plus my subs so I guess I should of said beforehand that I want to learn using 4-way and 5-way style sound.
There should be no "4 or 5 way style" sound.
In a proper loudspeaker system, you should not be able to tell how many "ways" a sound system is divided. You should not be able to hear the different bands nor see it in either the response or phase responses.
If you can-then something is wrong with the system. The only advantage that a "more way" system has over a single driver is output capability and/or extension on both the high and low ends of the spectrum. But in the "perfect world" a 5 way system should sound like a very good single driver-just louder.
If you want to "learn" about multiway systems, then instead of buying one to "play with", I would suggest learing about impedance & the loading effect-freq responses-crossover filter types-pattern control-interactions-wavelengths-proper rigging and so forth.
True it is not as much "fun", but you will learn a lot more that will help you when you get on a real system.
Simply learning how to hook it up is pretty easy-learning the science behind what is happening is a bit more of a challenge.
