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.
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. -Bruce On Tue, Jul 13, 2010 at 8:47 PM, C F <[email protected]> wrote: > I agree with horns you'll usually get better coverage.
