[QUOTE="turtlestrap, post: 8339116, member: 664141"] Would it be possible for you guys to review my subwoofer box design for the HDS208? I am designing a T-Line box for it. It is my first every box design and I have been doing a ton of research, so any input is highly appreciated. So, based off the Fs of the sub, 44.41Hz, a quarter of the wavelength is (1130ft/s)/(44.41/s)=25.6 ft/4 = 6.4 ft of port length. (76.8 in.) For a T-Line, we also want the port area to equal the area of the subwoofer cone. I assumed the piston diameter was the same as the diameter of the cone, so I got the area to be 32 in^2. So, I went into Google Sketchup and mocked up a design. Due to the small port area and size constrictions, I need to have the subwoofer inverted. So, I have a port of dimensions 12.5" x 2.5" x 76.8" [IMG]http://i.imgur.com/ClJNy9f.png[/IMG] [IMG]http://i.imgur.com/rn6iai5.png[/IMG] Thanks a lot! [/QUOTE]
