fmedina Posted September 30, 2011 Report Share Posted September 30, 2011 i never really understood this design. what are the benefits compared to a regular slot enclosure? these t-lines get low? Quote Link to comment Share on other sites More sharing options...
newls1 Posted September 30, 2011 Report Share Posted September 30, 2011 um, well, YES T-Lines get low. My T-Line has a single 8" in it with 288 clamped watts going to it, sumbish sounds nasty for what it is. I was very impressed.

fmedina Posted September 30, 2011 Author Report Share Posted September 30, 2011 So what's the formula/rule on building a t line. I'm interested on building one for my lvl 4 Quote Link to comment Share on other sites More sharing options...
eltortuga94 Posted September 30, 2011 Report Share Posted September 30, 2011 take 1130 (speed of sound) divided by the fs of the subwoofer DC lvl 4 12" is 27.4, so you have a 123.7 inch long port and keep a constant 76.5 square inches throughout of the t-line. Here's a link to forevrbumpn's post about it. http://www.stevemeadedesigns.com/board/topic/1828-quarter-wave-t-line-tutorial-updated/ Quote System: Basically Stock In process of upgrading Link to comment Share on other sites More sharing options...
Superjay Posted September 30, 2011 Report Share Posted September 30, 2011 T-line enclosures typically taper from large to small at the opening. The taper, regardless of length should end 38% small that the opening.

STEvil Posted October 1, 2011 Report Share Posted October 1, 2011 T-line enclosures typically taper from large to small at the opening.

Quote MickyMcD - "Capable of making some serious trouser flapping volumes at where's-my-testicles frequencies, the Servo-Drives used to be fairly jaw dropping..." Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.
