What pushes more air...?

Before anyone says " a 4x10 has 40 inches of area, and 2x15's only have 30," let's let a smart person answer.
The two configurations you propose have a similar surface area (the 15s having a little more), but their displacement (i.e. amount of air pushed) will also be determined by the excursion of the particular speakers involved. Conventional wisdom would have it that all else being equal, these setups will push about the same amount, but all else never is equal.
Man, I didn't know there was going to be math involved. And if there is, can someone do it for me?
If you round it off just using squares you could comparatively say that a 410 has 400 sq. in. (100 x 4) whereas a 215 has 450 sq. in. (225 x 2). But who's to say that one will sound better? They all differ so much in other ways than just cone area.
+1, factor in each driver's excursion and you'll get the volume displacement of air, gotta look at all three dimensions when talking about pushing air.
depends on the type of sound..
if your bass is sub-heavy, two 15's will push tons more and be/appear louder. if its mid rangy and honky, 10's. in general (not bringing surface area equations into it) i'd say two 15's can push more.

A pair of GK115RBS cabinets vs. one GK4x10RBS.
Through a GK400RB.
If it's not a huge difference, I'll go with the one 4x10. One trip up and down the stairs. Takes up less space in my apartment. And probably cheaper than the two 15s.

Insufficient data.
Incorrect. Go sit in the back of the class.
Also incorrect. Go sit next to him. :scowl:
Total 'air moved' is determined by the total driver displacement, T/S spec Vd. If you know what drivers the cab is loaded with you can look up the Vd on the manufacturer driver data sheet. If you don't there's no way of knowing, it's one of those critical pieces of information that cab manufacturers don't reveal.
owning a 400RB I'd say you're better off w/either two 1-15s to get 4 ohms to maximize your power or find two 2-10 cabs at 8 ohms a piece to give you the four ohms. That way you can stack them vertically (a big recurring theme in these threads, but it's true) for better dispersion of mids/highs AND you can hear yourself better. Plus those are easier schleps than a big 4 X 10 and you give yourself some flexibility for the kinds of gigs you're doing. YMMV, IMHO, IME, etc.

I corrected myself professor, thanks
The GK410 cab is 4 ohm. Both the 15s are 8 ohm. I do not know which speakers GK puts in these cabs.
