[QUOTE="Art Welter, post: 132127, member: 52"] Re: Sealed vs. Ported Subwoofer Enclosures in Pro Audio Relatively aged ;^), grew up listening to 8" Karlsons my dad built in the 1960s, the first cabinet I built in high school shop was a 15" Karlson, around 1972.Sold it ASAP. The Karlson exit looks more like a Christmas tree, internally it is a bass reflex. The Keystone has around a 10 foot folded horn path terminating at the floor. One of the dozens of exit shapes tried was more similar to the Karlson, but the keystone shape worked the best compromise between low end extension and a smoother upper end. [/QUOTE]
