"Ye canna deny the laws of physics, Captain !"One of which is that the simplest way to maintain intelligibility is for all sound to radiate from a single point.Another is that there's never enough space in the middle of our flaming fairground to park a pair of bulky spread-legged tripod stands ...so that the Motor-Mouthed Marshall's wise words can impress all around, ...from HALF the power-sapping distance that would otherwise apply.Or, how about the reverberation-induced need to have all the sound radiating from a single bracket, high up in the centre of the longest wall, to cut down the boxiness from standing waves ? K&M to the rescue.They've even included an Allen key for secure slide-adjustment of this sturdy spreader's box-section rails so that almost any enclosures can be accommodated. (Mine travels "rubber-banded" to its pole-socket.)Certified safe by Germany's TÜV and built like the Bismarck.What else do you need to know ?
