Master

Let's see if I've got this right: TruRTA has a sine generator, which I'd set to 1kHz, adjust level for 2.83vac (assuming 8 ohm) across the speaker terminals, then read dB spl at same settings with pink noise?

I tried something like that before, at 60hz, and noticed that if I read 108db with sine, pink noise would be maybe 100 or less. I think I was seeing what you said I should see.

What I'm trying to do is be able to answer honestly when someone asks what the sensitivity of my speakers is. In the above case, would it be 108 or 100?

Thanks,

John
