2 12s or a Single 15

[cougarballa2k5 0]

Which would be louder? Yes this is a stupid and somewhat hard to answer question, but which do you *think*.

Two 12s, each getting 600 rms

One 15, getting 1200 rms.

Of course, SI Magnum D2s....

assuming that the total power would be the same, most likely the same amp in each sinario. I would say the 2 12s would be louder simply do to cone volume, 24 inches total as oppose to 15.

Also depends on whether you'd be porting one or the other, or going sealed.. whats your preference?

You have to look at that in terms of SD

A single 12 is .05 sq M of SD, so .1 for the air

A single 15 is .08 sq M of SD

Then you have to factor in xmax (this is for general displacement purposes)

The pair of 12s is 2.4 and the Single 15 is 1.92

Now, the question lies in are the 12s reaching Xmax off of 600 per driver? The 15 assuredly is reaching it off of 1200 watts. The 15 could very possibly be throwing farther than the 12. And the gap is closed somewhat. I'm sure the two would be very close in terms of output. I would like to say the 12s would inch out ahead, since that is what I am going to be using .

EDIT - Both in their respective recommended ported applications.

The x-max value on the website is one-way, not peak to peak...

Two 12" Mags = 4800cm^3

One 15" Mag = 3840cm^3

I know it is one way. What is your point?

EDIT: I didn't mean that disrespectfully, I'm just saying, my calculations and assumptions were on it being one way..

Point it that a sub moves both forward and backward because it receives an AC signal...not a DC signal. I just didn't see much point in using one-way excursion when a sub moves both ways. You will arrive at the same values as I did if you multiply your numbers by 2, no biggie I guess...
