2 12's ported vs. 2 15's sealed?

[Weeznur32 10+ year member]

Hey i am goign to put some Fi Q's in my trunk. BEcause of space i can either put 2 12's back there in a ported box or 2 15's with sealed box. If it makes any difference it would be powered off mmats d300hc. What do you think would get louder? SOrry if this is a dumb question?

i would do the two 15's. I had the same option with Mag 12's ported or Mag 15's sealed and was told to go with the 15's sealed and i couldn't be happier. Plus if you ever get a bigger vehicle you can always port the 15's. Thats what i'm going to do when i get my escalade or tahoe.hth

Two 10's are equivalent to one 15. I would personaly go with the three 10's ported..

Their efficiency will be increased by being ported than if they or the 15's were sealed. The three 10's will have a good chance of having the highest sustainable spl than the 15's sealed or 12's ported, and you have more cone area than the 12's ported and more motor strength.

Assuming the power is sufficient, the subs are all of the same model in each setup scenerio (Fi Q's), and you have the room, Id do the three 10's ported.
