I bought a pair of Tapco S8 monitors - made by Mackie - for my T2 and they sound great. Not as good as headphones as other folks have pointed out but they produce a very clean sound and can get pretty loud. I use them in a room that is about 15x20 (feet). The Tapco line of products are a bit cheaper than the Mackie brand. There is also a powered sub available but I don't have it yet.
