what does size matter of the sub?

[Seehafer27]

hello, umm. im kind of new to this car audio stuff and i was wondering does a bigger sub do? (meaning 10" from 15")

Basically more cone area, more air movement (which is what you're going for)

[GAMEOVERCCA]

the larger the sub, the more air it can move. say you have 2 10's thats moving 20 inchs of air but if you have 2 15's there moving 30 inchs of air, so the response will be alot louder. the more air you can move as fast as possible with determine how loud you are.. there is aLOT more to it, but thats a quick rundown for you to understand tha basic idea of a subwoofer

generally speaking bigger subs can handle lower frequencies.

[i2ain2thunder]

also the bigger the sub the bigger the enclosure should be.

so 3 10" subs move the same air as 2 15" subs? or 3 8" subs move the same air as 2 12" subs?

you're almost as bad as Dr. subwoofer.

10" sub has ~80 in^2 of surface area
12" sub has ~115 in^2 of surface area
15" sub has ~175 in^2 of surface area
18" sub has ~255 in^2 of surface area.

that gives you a general idea of how much cone area you're talking about. for example, 2 12's have ~230 in^2 where as 3 10's have ~240 in^2

the bigger the sub, the louder it will be (in most cases) and the more air it will move. there are many more factors into how loud a system can/will be, but cone area is usually the first priority

yessir lol

i said thats a general idea, you really expect to explain the ENTIRE break down of speaker response and cone area, and low freq's and so on to someone asking the question he asked? i mean really speak to him in terms he will understand.. lol

[thegreatestpenn]

alot of fail in here.

OP size does have a few different aspects. the most important thing to remember is THERE'S NOT REPLACEMENT FOR DISPLACEMENT. the impact you feel from a subwoofer is sound pressure and that requires air to move. The more cone area you have the EASIER it is to move more air.

there's a difference between general ideas and false information..

Bigger woofers are better

Serious response, larger woofers (cone area wise) will be louder on the same power vs. one will a smaller cone.

Larger woofers usually have a lower Fs, lows FTW.

They also have a higher Mms, which means they may be a little, if you will, sloppier than smaller woofers.

Most of these things can be controlled by enclosure design, as well. So I like big woofers.
