i was thinking about starting to compete in some spl comp, but i really don't know what i should do. i was thinking doing MECA, and then doing CS3 i think. my setup will be 2 15" k series powered by a USX-1000D. should i go with meca, or with iasca, or what? also, since i've never been to a comp before, do you guys use sine waves or do you play an actual song? one last thing, can you place the mic anywhere, or is there some set parameters as to where you can place it? thanks for all your help in advance
