[QUOTE="PV Audio, post: 4486542, member: 554493"] I wouldn't trust the RE calculator if my life depended on it. Why did you chose those port dimensions? The larger it is, the more square you should make it. Round is the most efficient, but rectangular ports that are very tall or wide but very thin usually suffer bad compression which lowers the enclosure's efficiency. As a result, you lose output which I know you don't want if you're running dual 18s. Instead, try something like 12x12 or 13x13 or mix the dimensions for a more square rectangle. If you need anything beyond that, PM me and I'll help you out. [/QUOTE]
