I am assuming "full range" means like 3 or 4 way. 2 way- A woofer and a tweeter, the common speaker setup 3 way- A woofer, midrange(sometimes, or another tweeter), and a tweeter 4 way- A woofer, midrange, tweeter, and supertweeter
Go with 2 ways, unless you are getting components and want to mount a midrange somewhere with a 3 way. Just because the 4 way has all that crap doesn't make it better. Sure, there are decent 4 ways but 2 way is all you need. Generally, they just throw a bunch of types of speakers in one and try to sell it to you (4 way). Especially if you use a crossover on a 2 way speaker. Generally, the woofer becomes an excellent midrange as well.
