2x12", or 1x15" - Which is best for MAX SPL?
I've got a dillema. I'm building a big box, and I can put either 2 x 12" subs, or 1 x 15" sub in it, but not both as I would like. I want to make the maximum SPL. The box will be ported, obviously. I'm driving it with a class D amp which is rated at 1500 watts x 1 @ 14.4v, 1185 watts x 1 @ 12.5v. Either way, my 15" sub is an oldschool Cerwin Vega Stroker 15" dual voice coil which will be setup in parallel for 2 ohm load. My 2 x 12"'s are also oldschool JBL GTi1200 1000watt (600rms) 4 ohm, which will also be wired to 2 ohm load.. I'm using 1/0 gauge for power with multiple batteries and caps, but it's not relevent. The 15" put's out a bigger sine wave, however the 2x12"'s would have a larger surface area, but slightly smaller sine wave.. I just dunno which one would be best for max SPL? I'm leaning towards the 2x12"'s..
So which is better? 2x12", or 1x15"??
What do you mean a bigger sine wave?
from personal expierience, 2 12 with less power... louder then 1 15 with more power.
