6 12s vs 4 15s

[Migz124]

I have the option of using 4 15s Sundowns zv5 and or 6 12s zv5 which would y’all prefer? ( Both would be walled and I’ll be using my bc13k from Crecendo it’s what I have laying around ).

The 4 15s will have significantly more cone area

Flip a coin.

6 12s will be slightly less cone area but more motor force.
6 12s will be more expensive
Plus you will probably want quite a bit more power for 6 Zv5s. Honestly I would want more power for the 15s as well.

Do the math. No replace for displacement.

But subs are naturally aspirated. So cone area is king.

What about voice coil venting... That's a power adder!

Got nozzzz on my kickers. Planning on twin charging them soon....

10-14 square inches is certainly not a significant difference.

That said, I'd mock up the area you have for a baffle and cut out some 12 and 15" rounds of cardboard or something and just start playing around with placement and see which will be physically easier to put together in an orientation you like that allows whatever port options you're after. If I ever get good weather and free time to coincide I'm really itching to rebuild mine to try to squeeze in 8 12s but I haven't even got as far as to see if I can do it and have adequate port area. I know I can do 6 easily but I don't think 50% more power handling is quite worth the effort it'll take to do the carpentry plus the cost of rebuilding that many subs, especially since I don't think I have more than a couple 12" frames here.

What would the final ohm load be if you did that for 6 12's vs 4 15's? I almost say do the 6 12's because it's quite a bit more motor force.
