Could anyone please provide me with the formula or where can I find tables of the relationship between input watts and output dBs in a speaker?

I want to calculate for a certain sensibity speaker the watts needed to perform at differemt dB levels

Thanks a lot

The sensitivity is the output at 1 watt for an 8ohm speaker @ 1 meter. For each doubling of wattage, output is increased by 3dB.

It's been a while, hasn't it.

I don't really plan on staying that long. I occasionally pop in to look at the thread titles and read a few. Maybe once every few days, or once a week. A lot less than once every hour or so like I used to!

I see you guys have a few new members; good for you. New blood is always good!

Anyway, off to either watch whatever accumulated in the PVR, or listen to a bit of music.

Have fun!

Thanks a lot to both of you, i really got what i wa looking for, now i understand why the difference between 88 and 91 dBs in sensitivity is so important when using a low power amp
