General opinions 18" or two 10"

which would you prefer and why.

I see alot of ppl saying the larger subs reproduce lows easier and or better, Is there any truth to this?

Larger sub (of the same design/model) usually means lower fs, but not by much. Enclosure design will dictate frequency response much more.
One 18 will have considerably more cone area than two 10's. Extrapolation from there is up to you.

So more cone area means in theory the 18 properly executed has the potential to get louder?

Im not saying more cone area always wins out. But the sheer difference in cone area will more than likely make up for the 10's having the efficiency advantage of being ported.

i thought 2 10s have a slight bit more cone area so they with the same power as the 18 cn get louder ??

what if the 18 is ported?

nah its not 10 +10

18' ftw

18' ftw

I agree 18 ft. sub ftw. lol

Cone area of two 10" subs: 2 x (Pi x (radius squared)) = 2 x (3.14 x (5 x 5)) = 157 square inches.

Cone area of one 18" sub: (Pi x (radius squared)) = (3.14 x (9 x 9)) = 254.47 square inches.

Now these are calcs for flat circles, so they don't consider the slope of the cone, if that matters.

One 18 has more than 50% more cone area than two 10's.

what if the 18 is ported?

Well if the 18 has that much more cone area AND will be ported, the difference between it and two 10's ported is not even close.

Well I am glad I went with one 18 then. Hopefully when I get a new car I will have enough room for 2. Then the real fun can begin.

they biig

so does that mean it would take 4 10s to get to the cone area of 1 18 ??
