Well, these are horn speakers with 30 Watt which will receive 10 Watt only from Amplifer. I am not connecting them to ceiling so maybe 10 feet off the ground. I guess my coverage would be better???<div><br></div><div>Based on your calculations for for 40k sqfeet that would be 33 speakers. I think that's way too much of an overkill.</div>

In my experience using height for radius works, for example if you<br>
have a 20 ft high ceiling then the coverage for one speaker would be<br>
40 ft diameter circle (around 1200 sq ft). Of course overlapping 5 ft<br>
has never killed anyone, but this really depends on the power of the<br>
speaker, I usually deal with 70v speakers tapped at 16 or 8 watts<br>
depending on how many speakers I put on one amplifier and the output<br>
wattage of that amplifier.<br>
