[QUOTE="Papermaker85, post: 8460462, member: 572595"] designing a transmission line is tuff. you have to taper the port but i actually like to play with the initial chamber size more so than worrying too much about the tapering. the length of the wave from the rear cone to the mouth should be the same wavelength as the FS of the driver. depending on the drivers compliance and suspension stiffness is going to vary the FR. the taper is to help breakdown standing waves but i perfect to keep the port at least 1/2 the SD of the woofer.. you just got to play with it a bit to get it just right but the benefits are excellent.
