Thanks fro the input. The area is a 40000 square feet. So, you are saying that if I use four speakers then they would not be as loud as needed?<div><br></div><div>Thanks again <br><br><div class="gmail_quote">2010/7/9 Massimo Nuvoli <span dir="ltr"><<a href="mailto:massimo@archivio.it">massimo@archivio.it</a>></span><br>

</div></div>Hummmm interesting... i never checked this kind of product.<br>
<br>
CyberData has calculator only for the 8W model, but... every speaker<br>
they sell is 8w and the calculator say 69 speakers. You can attach 2<br>
speakers to one amplifier in parallel (they say this also), this is<br>
the maximum as the amplifier cannot reach 32W (4 speakers), but you<br>
can try to use 4 speakers (2 in parallel + 2 in parallel) with a<br>
little less than maximum 8w on each speaker.<br>
<br>
I think a reasonable number of speakers may be less than half, but you<br>
must check wath is in the area, also remember if this is a warehouse<br>
to place the speakers where a person can be, not goods. :-)<br>
<br>
For a so big installation think to use a voip interface and<br>
professional product with low voltage line speakers, i think is less<br>
expensive.<br>
<br>
Bye.<br>
