I don't know where you guys are getting that a truss takes more room. My photo above; 2 stands...thats it....nestled between is a 4 foot cart.
2 T bars, 2 speaker stands.....what takes more room? 2 speaker stands and one t bar....more room, if you're setting up the T to the side....To the back, you've got sight issues....
That being said...Randy's set up does look look nice....Bear in mind...How many wedding venues can you spread the speakers that far apart....
