Help With T-line For Pc Sub

[schultzy]

i have some 6.5" and 5.25" speakers lying around and i was thinking of building a t-line enclosure and use it for my computer sub. i only have about 15-20 watts to put out so a t-line should be perfect

can anyone instruct me on how to build one of these things? i can build anything,i just dont know enough about what size port and all that stuff

is there anywhere i can go to read up on how and why these things work so good
