#175553 - But why do you think that it is relevant? Responding to: ???'s previous message |
150W peak, 75W rms - but I don't think it has enough cooling for 1 hour at 75W.
http://www.maplin.co.uk/Module.aspx?moduleno=3265 150W peak, unknown rms. And based on size - how much heat can it transport away? http://cgi.ebay.co.uk/ws/eBayIS...=WDVW&rd=1 150W peak, 75W rms - but how much heat can the 63 gram heavy horn transport away? http://www.maplin.co.uk/Module.as...63&C=20369 150W peak, unknown rms. How much heat can it handle? http://www.cybermarket.co.uk/ishop/923...r5502.html 150W peak, unknown rms. How much heat can it handle? http://www.cybermarket.co.uk/ishop/923...r2774.html But the question is still - why is it relevant? If you intend to use it for music, then the power at 10kHz is very, very much smaller than the power in the bass range. And if you intend to kill dolphins, then we are talking about special hardware, in which case there exists datasheets with the relevant information. The normal way to use this kind of tweeters in a sound system is to have a series resistor to reduce the possibility of a high-frequency fedback loop. But you normally don't a filter to strip off the low-frequency sound since a piezo horn has a very high impedance and works capacitive. It basically ignores the almost-DC signals for the bass. |
