I agree with horns you'll usually get better coverage. I have done this in the past with 5 speakers for a 30k sq ft warehouse very good coverage. Using bogen horns. This was for a 300ft by 100ft warehouse. Starting at 30 ft of the 300ft wall at the 50ft line off the 100ft side I installed a horn every 60ft alternating facing one north and the other south, which ended up 3 facing one way and 2 the other. You can get double horn speakers which will face 2 sides. I wouldn't mount them on the wall specifically not so low as fork lifts and what not will damage them.
