How many DB (4) F1 subs packed together??

How many DB do you get if you have (4) F1 subs packed together??

Just curious...

I don't  know how many?

Was this a riddle?

Looking for the tech specs... not a riddle.

I searched and could not find the answer in the forums. I know one is 130 dB so adding another would give 133 dB and adding two more would give you a max dB rating of 139?? Seem too high...

theoretically, yes 139, but who really cares.  You either have enough output for your needs or you don't.  Manufacturers, including Bose don't generally publish the exact conditions of how they were measured, so it's only used a general idea.  Don't look too into it....

Hi jdbassentertainment.com

The numbers are theoretical. Ask an acoustician if the numbers are an accurate predictor of performance and they will probably say, "it depends."

Note: Some algorithms predicting increases in dB rely on all the drivers being in a sphere that is within one-quarter wavelength of each other. You're probably okay with two F1 Subwoofers side-by-side, but when you get to four, the drivers are no longer within one-quarter wavelength. The outcome is more complex.

Check out this article.

Everything you wanted to know about subwoofers

If you could come up with a number, how would you use it?

Generally 6 dB per doubling (3dB from the matching additional source, 3dB when the sources are coupled a.k.a. nearly phase coherent).

So:

1x F1 Sub - 130dB Peak

2x F1 Sub Coupled - 136 dB Theoretical Peak

4x F1 Sub Coupled - 142 dB Theoretical Peak

3db from 3dB from the matching additional source?
