    Maybe a dumb question, but what do I put for SPL Power(W)parameter?(under the plot tab). This is for a Tempest.... Also, anyone know the Pe or the Z parameters? Thanks!

    Depends what you want to do. If you want to compare plain old SPL then use 1 watt. I like to put in the max power of my amp so when I click on the SPL tab you can see the max SPL of you driver at XX Hz. For example: I have a PE 250 so I put 250 in for the SPL Power. Then I click on SPL & I can see that at 20Hz I can achieve (theoretically) a max SPL of 107.18 db.

    Pe is 400? Might be 750 but I think that is Pe max?????
    Z is 4 (2 8ohms in parallel = 4) That's what I use anyway.
