PA System for a T3

Hi all! I’m new to the forum and just got my T3. Guitar is my main instrument but I will be implementing the T3 into the mix. I play one Mesa Triple Recto thru a Mesa 4x12 stereo with another Mesa head and 4X12. I need a small PA to keep up with this combo. I’m specifically looking at the QSC K and KW series. I was thinking one K12 and one KW181. Or would a 15" monitor with a sub be a better setup? A 3-way setup? I figure that’s unnecessary since bass is the name of the game with the T3. I also plan on using a Access Virus B or Indigo down the road as well.

I’m looking in the direction of powered speakers to eliminate the need for a separate amp. I can get a good deal on QSC stuff so I’m looking at getting the right sound and not so caught up on price.
