SPL Calculator

[Stalin-ohaulic]

I wrote this SPL calculator back in 2005. It will actually get you pretty close. Check it out. I know that it can't be precise due to too many variables not factored in BUT give it a look. Check out the forums. Chat with the Stetsom Rep.

Cool stuff //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif it says I'll hit 138dB lol if I ever get my system metered after it's assembled, I'll let you guys know how accurate the guess was haha

 

[Stalin-ohaulic]

It's strangely close most of the time.... Try to get it to set some world records. It's pretty tough.

guess it doesnt matter if its 3 8's or 3 18's

The theory was that efficiency is a factor of displacement, so stating the displacement of the cone was irrelevant.

For instance most 18's have a 1w/1m efficiency of over 90db. Find me an 8 that has that.

Ok, it says I should be doing about a 142. One day ill get it metered and see. Definitly seems like it should consider the woofer size.

Try it out. I'll be back later and I want some feedback //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

it told me 127 which i find to be kind of low for a 12" type-x tuned to 34 getting 1200rms considering i have a pair of 10w0 subs tuned to 35 getting 200rms each that have broke 140 at the window sealed on a tl.

that is the stupiest thing ever i hit 125db wit 1 15 on 2400rms
