Was thinkin goin sealed but gona stick with amp combo in sig so gona port it so i can get the most out my amp n sub.Gona go with the smallest rec ported box for the 18..5cf. Want to kno if my length n sizes r right. 5cf minus sub n port displacement, would a 5in diameter port with a 6.7in length give me about a 32hz tuned frequency?
