I'm sorry that you couldn't understand. Is this better? It's not like I'm writing an paper for school. I would still like some feedback please. I thought this was a reasonable question. Either you have 2 18's with 6 cuft a piece or you have 3 15's with 4 cuft a piece. The 15's are rated at 2.8-4 cuft @ 28-33Hz per speaker. The 18's are rated at 6-10 cuft @ 28Hz per speaker. If I only have 12 cuft to build a box then I need to know if 3 15's in optimal conditions would be louder than 2 18's with less then optimal conditions. THANK YOU to everyone that helps me out.
