[QUOTE="slaphappy, post: 79572, member: 545220"] Ok, I thought the sub would have a recommended volume for a sealed enclosure... NOPE. I have some books but they don't help. These are the specs in the manual: Fs = 27Hz Qts = 0.30 Vas = 3.2 Ft^2 Qes = 0.32 Qms = 5.0 Sd = 490cm^2 I don't know what any of this means. My book says: fob = Fs/Qts ... so Fob = 90 Vof = Vas * Qts^2 ... so Vof = .288 The manual then says to always make sure you make the enclosure 10% larger than required. Vof = 0.317? Woofer internal volume = .19 Ft^2 So... 0.507 is the volume needed? The manual keeps using ft^2 (feet squared). Isn't it ft^3 (feet cubed)? HELP ME PLEASE [/QUOTE]
