Yes, thanks. I think lots of manufacturers just boost the number of speakers really needed but again this really depends on the environment noise level. Regards, Bruce On Wed, Jul 14, 2010 at 11:50 PM, C F shma...@gmail.com wrote: I'm happy to hear it worked out so well with so little. :) On

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

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??? Based on your calculations for for 40k sqfeet that would be 33 speakers. I think that's way too

In my experience using height for radius works, for example if you have a 20 ft high ceiling then the coverage for one speaker would be 40 ft diameter circle (around 1200 sq ft). Of course overlapping 5 ft has never killed anyone, but this really depends on the power of the speaker, I usually deal

Hi Guys, I am looking to buy a 25 Watt output CyberData VoIP amplifier and to use 2 Bogen sp308a speakers with it for a 40, 000 squar feet area and 21 feet height. Is that enough? Is there calculator online I can use to determine the number of speakers needed? I guess these speakers go in chain

Thanks fro the input. The area is a 4 square feet. So, you are saying that if I use four speakers then they would not be as loud as needed? Thanks again 2010/7/9 Massimo Nuvoli mass...@archivio.it bruce bruce ha scritto: Hi Guys, I am looking to buy a 25 Watt output CyberData VoIP
