Just my 2 cents, but I prefer the powered monitor stereo setup, especially to hear those fantastic sounds that come out of the T3.

Mackie 450s are my choice. Very easy to lug and setup. On the floor pointing up provides crystal clear highs and nice bass.

Everyone has different tastes and it took me a lot of effort to come up with something that made me happy. Sounds like you'll go through the same process

Good luck.
