Thanks for the input guys. For other refrence, a CyberData Voip Amplifier which supplies 10 Watt to each of the two bogen 30 Watt speakers did the job for a 35,0000 square feet warehouse with environmental noise level of slightly higher than standard but not those of industrial.<div>
<br></div><div>Only two speakers and done deal. Though I know that three speaker would have been the perfect solution but 4 would cover every single little corner and be an overkill.</div><div><br></div><div>-Bruce<br><br>

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