[attachment=232998:orange.jpg]Hiho-I use an Orange TB500 with a SP212 and an OBC115 .
I am very happy with them.
SP212-small ,one hand lift,tight sound and very loud with loads of bottom.
OBC115-big,heavy,load it in on a trolley.Looser sounding,growls more,very loud.
Both together-can go insanely loud with more to come,volume at 10 0clock,about 4 in the other scale.
They go very well with the TB500 head.
If your after sound-OBC115,if space and weight is the deciding factor-SP/OBC212 but either is good
