Bob,
Peak values for voltage (excursion) limiting are going to be based upon instantaneous capability which would rely on the amplifiers reserves rather than directly drawing it from the wall.
In fact all of the limiter values related to saving your drivers from damage will be related to the amplifiers output and not to what it is drawing from the wall.
If this is the same spreadsheet from Crown that I have be sure you are using the correct wattage values in the correct fields since JBL gives 3 values on many of their spec sheets (continuous, program, peak) and asks for 2 HR. and 100 HR. values when you fill in the spreadsheet.

Thank you. Yeah, figured the "bulk" of the power would be coming from reserves. My thought was, using Ohms Law, the amperage parameter needed to be factored into the equation to get a "meaningful??" value in watts.
The Limiter Wizard I'm using is the spreadsheet from Crown. Yep, values entered into it are correct for their respective areas. I'm probably showing my ignorance here, but the peak ms value for the attack time seems sort of long (I don't have the data in front of me at this time)... but was thinking it was around 60ms (15hz). I referenced manually setting the peak to around 40ms (to restrict the low end to around ~25hz). However, I do have my dbx-260 rolling off around 30hz on the "low side" of the low-pass filter, so this may be all just "words and crap" at this time.
If I do a "reverse lookup" to determine voltage, based on watts, I get a different voltage number for the SRX 3200 watt RMS rating... still, I'm needing to enter an amperage value to determine results.
