I’m there with Hessler. I have a pair of K12s I absolutely adore. They are wonderful. I would suggest those over anything else on the market. (The EV ones are second on my list, especially being able to use the 15’s and at that price, can’t beat it).
A controller and a macbook all day would work very well. My Advice would be to pick a controller based on what you feel is best. Go to your local Guitar Center or Sam Ashe or whatever and take the time to play with those controllers. I personally like the Xone:DX (because I have it and mixing on it is ABSOLUTELY FUN. Plus with some DNS-3700, brand new dimension to sound) but I’m eyeballing the new Pioneer stuff…
