How much into play does cone area effect?

4 15" subs at 1600 rms... vs. 1 12" sub at 2500 rms....

Obviously this is one of those questions... "What will get louder" but its not fully....

I just am wondering if cone area will play a big part in this.

Both sets of subs would get there full RMS and be in there recomended box's.... and just imagine that everything was done perfect.

I would pick the four 15's...no question.

Explain.

we have to know the subs duh brand makes all the difference

Explain.

Because you'd be running up against power compression with the single driver, mostly likely...and not even taking that into account, the total swept area of the four drivers compared to a single one is not even close. Move more air; you get louder.

easy, type-R

the 12 could be louder, its all based on xmax (how much the sub can move)

Oh really? Care to explain why some of the loudest SPL drivers dont have amazing xmax?

Because the enclosure couldn't have anything to do with it...nahhhhhhhhhhhh.

i would most definitely go with the 4 15" at 1600wrms, cone area is the deciding factor on my decision.

in real life there would be actual parameters that would be taken in to account.

on paper the 15's look good, not always the same on the mic.

i can definatly tell you it will sound louder to the ear... but that doesn't mean they will automatically be louder on the mic //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

If SPL is directly related to moving air. What sub parameters should one look at to achieve a higher SPL??

hmm.... this is interesting.

Glad to hear that about the cone area.... now its just time for the box //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

if your wondering, you'll look better with the 15's

15's... when your about to have a heart attack and you look back and see the subs barely moving... now that's a good feeling.

are you actually putting 4 15's in ur car?
