[QUOTE="Lowlacs, post: 8155361, member: 642968"] 4cubes *after* port and sub displacement. Even two 12s would be short on cone area vs 1 18. How to figure cone area? Pi x (r x r)=cone area. Pi=3.14 and r= radius(half diameter) of subwoofer. With that bein said 2 properly powered 12s in a custom enclosure could very well out beat one 18 in a prefab box. There are many other variables to consider. [/QUOTE]
