[QUOTE="bbeljefe, post: 8205094, member: 655960"] ¼ wave t-lines are normally tuned to the driver's Fs and the volume of the cabinet is determined by tuning frequency & the surface area of the driver(s). Generally speaking, a 30Hz tuned line for one ten would be about 3 cubes. For two, it would be exactly double. For a fifteen it would be ~9 cubes. But a transmission line isn't a box, it's a line. In simple terms, it's one long port and the length is determined by dividing the speed of sound by the tuning frequency and then dividing the product by 4. Hence, ¼ wave(length) line. They are incredibly efficient alignments from the top of the sub bass range all the way down to about one full octave below tuning. [/QUOTE]
