well that wasnt hard

That is at 2.83v. 2.83 volts is 1w/1m @ 8 ohms. At 4 ohms it's 2w/1m which means a doubling of power and +3db. This means it's actually 87db 1w/1m. Nice try though. Look it up before you argue... so yeah... that WAS hard.

Audio control meter or term lab? I have a term lab and I've metered a ton of people. I calculate them with this and it's always close. I have to assume you guys are picking the wrong options. It won't be 100% but it gets **** close for a daily tuning (

152.1

Wow!

It was really close when using the amps rms rating. When using actual clamped rms it was way off. lol

HAHA yeah.. there are a lot of flaws with it, BUT if you were going to buy a setup and had no experience... you can sort gauge equipment's potential. Of course it's all dependant on the install but it can get you a decent ballpark of what you'll hit on the TL.

HAHA what is your sensitivity and transfer function?

Hmm what is her setup? I wonder why it's off so far. Btw register on my forums so you can tell me what an idiot I am there... at least if you hurt my feelings it will help build my forums up.

Keep tryin it out.

I have an efficiency calculator written also that will calculate 1w/1m @ 50 hz based on T/S parameters... but I can't find it to post it. I think people would get good use of these two utilities. You could get through the bs of which sub would actually produce higher spl at a given power level if all other factors were equal.

said i should be around 137 right now. and 143.75 when i get my HDC3

Have you been metered yet?
