Hey all, I've been thinking about designing a smallish t-line to go into my dorm room for quite some time now. I plan on using a 6.5" Tang Band woofer, the specs of which are: Frequency range: 38-800 Hz • Fs: 38 Hz • SPL: 83 dB 1W/1m • Vas: 0.416 cu. ft. • Qms: 2.65 • Qes: 0.47 Qts: 0.40 • Xmax 13 mm • Dimensions: Overall diameter: 7", Cutout diameter: 5-1/2", Depth: 3-5/8". According to my calculations, I would need about 28 sq. in. of port and a line length of 97.5" for tuning of 36hz. My main questions are; should I bother adjusting the line length to tune the box up by just 2hz, or is 36 going to be close enough? Also, I've seen and read a lot about adding a sort of dampening material throughout half of the line; is this actually necessary/required in order to have proper response, or is it just an extra step that someone more experienced would take in order to get everything they possibly can out of their setup? Lastly, I'm open to any constructive criticism of my box, so what do you guys think? Sorry for the long read, now here's the box:
