matt scarlett Posted April 19, 2013 Report Share Posted April 19, 2013 floor pan t-line for my friends Kenwwod 12" sub and it turned out well. So i did a concept with a JL Audio 8W3v3 around 27Hz and so i did one for the I6SW ... never got around to fitting it, however with the 8W3v3, it hit really low. 8W3v3 enclosure made with recycled MDF Onto I6SW build Hybrid Audio Drawing with Bic Biro - went hideously wrong Link to comment Share on other sites More sharing options...
Watch the bass Posted April 19, 2013 Report Share Posted April 19, 2013 http://www.stevemeadedesigns.com/board/topic/164798-chasing-some-6-or-65-subs-not-mid-drivers/ and sorry, didn't mean to make almost the same exact thread lol though im looking for something to use to mock up wave guide enclosures, so was asking a little different qualities out of the sub. Don´t worry, if you give "6.5 sub" in the search function, it want work in the forum.

revoracing247 Posted April 19, 2013 Author Report Share Posted April 19, 2013 i love transmission line builds! thanks for posting them up! and how do you know what amount of port area to start with? it's obviously way above the SD and i haven't been able to find good info on what to start with for port area on tapered horns and expanding horns and such I think you have a bit of truck stuck in your mud bro ~Ford Ranger, ext cabKenwood DDX4701/0ga stinger wiring for big 31/0ga ofc flextech wiring 3 kinetik 800's AQ2200 @1ohm Sundown Audio X15 in a 27Hz tuned ported box LE BUILD LOG!!!

Chris Hammer Posted April 19, 2013 Report Share Posted April 19, 2013 http://www.parts-express.com/pe/showdetl.cfm?partnumber=264-919 I would try one of these. Relatively low fs for a 6" driver IMO.

revoracing247 Posted April 19, 2013 Author Report Share Posted April 19, 2013 i think im gonna go with the TB W6-1139SIF, more xmax, cheaper, and still a good fs for playing with designs I think you have a bit of truck stuck in your mud bro ~Ford Ranger, ext cabKenwood DDX4701/0ga stinger wiring for big 31/0ga ofc flextech wiring 3 kinetik 800's AQ2200 @1ohm Sundown Audio X15 in a 27Hz tuned ported box LE BUILD LOG!!!

matt scarlett Posted April 19, 2013 Report Share Posted April 19, 2013 There are different thought and theories with the size of the 'Line Terminus' (T-lines, as I'm lead to understand from my days in both Home Audio and Car Audio, don't have a 'Port' as such). I don't want to get into trouble for linking to another forum ... so here's the google result. And click the link that TALK .. s about AUDIO in the UK!! https://www.google.co.uk/search?q=transmission+line+fundamentals+pdf&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a#safe=off&client=firefox-a&hs=pOM&hl=en&rls=org.mozilla:en-US%3Aofficial&sclient=psy-ab&q=transmission+line+design+fundamentals+&oq=transmission+line+design+fundamentals+&gs_l=serp.3..0i22i30l2.46377.50388.0.50963.10.10.0.0.0.1.216.1160.2j7j1.10.0...0.0...1c.1.9.psy-ab.2av4Yhcnbn0&pbx=1&bav=on.2,or.r_cp.r_qf.&bvm=bv.45512109,d.d2k&fp=785b9e98f4101809&biw=1660&bih=840 I found at the start of the line, if you go too much above SD ... you start hearing the box, and it give a hollow sound. Keep to 2 x SD at the most. As for the line terminus, as the transmission line design fundamentals paper states, 2:1 ratio is a good place to start. One has to go a tad above SD to accommodate the width/size of the sub. In most cases this can't be helped! But IMHO, when it comes to T-lines, worry less about 'Area' and concentrate on; 1) Line Length - to determine the depth of bass 2) Wave Guide position and Line Terminus (height, as width will already be determined by the size/width of sub) to determine the output of course there is a bit more to it, however for personal listening tastes, there is a bit of trial and error. In the case of the I6SW, I'm always experienting between depth and output. If you aim the 'Tuning' (again, one doesn't really 'Tune a t-line) around 5Hz above the given FS, this will be good for overall output. However, once again, wave guide position and line terminus have a massive effect on this. Link to comment Share on other sites More sharing options...

CstrokerV Posted October 8, 2019 Report Share Posted October 8, 2019 Cjack why would you post on a 6 year old thread ? And not just start your own? And you didn’t even give any needed info on top of that my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/ Link to comment Share on other sites More sharing options...
