A glaring flaw in it is the cabin gain part of it...this is hugely important, why I compete in S1 and get my *** ***** by CRX's running the same kind of setup. The amount of airspace you have to pressurize is very, very important.

Here is something you can check out, suppose to be very accurate:
Basic db formula

//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif According to that formula, my old setup with IA 187s was hitting 145.X at 29hz. Upgrading to IA LIs is getting me 144.X. All I did was upgrade subs?!! =p

There is a free program you can download. My friend had it, how accurate it was im not sure. Never messed around with it, but wanted too, although I forgot the site. I will ask him the link as soon as I talk to him. The program is only freeware but you can pay for it and get the full usage out of it.

Sorry it took so long, I finally talked to my buddy today, and here is the link.

Im going to download it now and mess around with it, maybe I will be able to find a way to make a patch/hack for the full verson and what not.

But like I said, I havent messed with the program yet, I just knew that my friend had it.

Good luck!

What exactly does this program do?

 

[audiofanaticz 10+ year member]

Well considering the name of the post, I think you would be able to measure spl with it? hmmmm kinda odd huh?//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

like I said I havent messed with it really, and if you would read the site, Im sure they would explain what there program does since they created the program. Dont yea think?

i was just messing with it and it said my computer sub hit a 122db...............lmao

I know you need to calibrate your mic, there is a option to do that, and depending on the mic your using its not going to be very accurate, such as with any program.

Ive already heard of factory car stereos hitting that high, so you never know :/

Ok, I just got done reformating my pc, and most my neighbors are away at work, so its the perfect time to bump and play with my house stereo.

I ran through a few hertz and grabbed pics of the highest db with 2 different mics.

Mic 1 was some Piezo mic that looks really old and belongs to one of them old tape recorders it looks like.

Mic 2 was from my logitech headset that I bought from walmart for $20.00.

With Mic 1 I got 108db @ 57hz

With Mic 2 I got 91db @ 57hz

57hz was the loudest for my home stereo.

My home stereo consists of Two 100w x 4 sony recivers (2 towers of each one running only channel A), and four Tech speakers, each box has two 15inch woofers, and one big horn tweeter, and one 300 watt 12 inch powered sub.

My room is about 29 feet long, by 18 feet wide, and about 8 feet high. My 4 speakers are on one side of the room, and my pc is on the otherside, so there about 29 feet apart. The mics where both tested in the same corner at the same height right by my pc.

I want to say that 108db and 91db is the most the mics could handle. I could whack the mic on my desk and from 500-20k on the program the bars would jump a little more, but nothing over them numbers listed above.

rsmithjrs3, what where you using for a mic to be getting 120db? and was that thing sticking in your computers subwoofer port or what? Because I highly doubt that your one little pc speaker is louder then my eight 15s, and one 12.
