Nightshade Posted August 1, 2009 Report Share Posted August 1, 2009 Actually a tline is nothing like ported, in fact opposite if anythingI Vote T-lines my self, as long as your NOT doing straight up SPL, but cone area to cone area, watt to watt, I vote tline for efficiency, and low end What a tline is, is a guide, your Only delaying the rear wave from the front wave until the rear and front wave re align and create a whole lot of bass A ported box on the other hand is pressurizing air in a box, and using a port as a valve in a sense, open the valve enough, you will get more air flow If you wanna get technical then yes, but a t line is the same as a ported box with a really long port. How it acts is the difference. I don't really care for them myself unless your running under 1k watts. Anything over that I think that they lose their effectiveness.

Forevrbumpn Posted August 2, 2009 Report Share Posted August 2, 2009 pressurized box vs free flowing, if you look at the differences on a impedance graph, its completely opposite. If your talking about a - I think its called a choked transmission line where there is a cavity, even then they are still different The tunnel is not a port, but a tuned wavelength I have done ported boxes where you tune the port to a quarter wave, and its just not the same, you need to do a smaller area port Tlines sound different, react different, work different Quote I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.

Fish Chris Posted August 2, 2009 Report Share Posted August 2, 2009 (edited) Okay Forevr. I'm strongly considering a t-line right now, for my two 12"s. And I'm trying to learn all I can about them. I always hear people say > A t-line will get just as loud on half the power. Okay, that's fine, but if my power stays the same {700 wts RMS for my two 12"s} will that help ? Currently, I have my two 12"s in a tuned ported enclosure (3 cubes, to about 32hz) and they sound great..... pretty loud, and very musical. I'm just bored, and want a new toy. But too poor to buy bigger, badder subs or amps. So I'm thinking about t-lines. How would "you" compare the output of a couple 12"s in a correctly built tuned ported enclosure, to that of the same 12"s, with the same power, in a correctly built t-line ??? A little louder ? Cleaner ? Flatter ? Deeeeper ? Just trying to decide if it's worth it. I know every enclosure has its +'s and -'s, and if the only minus with a t-line, is that they are really big, I think I can handle that........ but I wouldn't want to go through all that trouble, and take up all that space, if I (and the people I showed it off to ) didn't say, "Holy $#!+" ! And again, I have a really nice ported enclosure right now.... Forevr ? Anyone ? Peace, Fish Edited August 2, 2009 by Fish Chris Quote Link to comment Share on other sites More sharing options...
keepinitloud Posted August 2, 2009 Report Share Posted August 2, 2009 In your opinion what type of enclosure would produces the most bass??SEALED? PORTED/VENTED? ANGLED? BANDPASS? I'd go ported you don't need alot of power to get good sound from your subs bandpass are very efficiant but in a very narrow bandwith and the sub has to be one that can be put into such a box. one note of caution with a bandpass box you might not realize your pushing the sub to hard and kill it Quote 06 chrysler 300C Hemi one mmatts dreadnaut 15 powered by a planet audio vx 2200d fosgate p200 running planet audio 8" midbass drivers and super compression tweeters stock battery and a stinger spv44 Irragi 300 amp alternator big 3 1/0 http://www.stevemeadedesigns.com/board/topic/55075-system-in-my-300c/page__view__findpost__p__763656__fromsearch__1 Link to comment Share on other sites More sharing options...
Darksideofsound Posted August 2, 2009 Report Share Posted August 2, 2009 What a tline is, is a guide, your Only delaying the rear wave from the front wave until the rear and front wave re align and create a whole lot of bass explain......i wanna learn more.....

kirill007 Posted August 11, 2009 Report Share Posted August 11, 2009 I vote line too, once you heard a tline, you will never want to go back to ported or sealed. only - is that the box is big.
