Memphisman Posted August 16, 2010 Report Share Posted August 16, 2010 i have been messing around with tlines recently and the one i am using is for 1 12 mtx thunder 7000. i was on youtube and saw a guy take his tline and put 4 8's in it, here is the video of what it looks like : box shows at 6 secondsI am wondering if that kinda defeats the purpose of a tline, if it doesnt i would like to do it to mine as i dont want to make another box for my other speaker unless i really have too.

kandiman71874 Posted August 16, 2010 Report Share Posted August 16, 2010 Apply what you have learned about t-line theory in regard to port area and cone area then look at that dudes port on that box in the vid. Do you see a problem?

Memphisman Posted August 16, 2010 Author Report Share Posted August 16, 2010 i figured it was that way the port on his is way to small but for every speaker you add in a tline, you have to account for the added cone area so more square inches righr?

Memphisman Posted August 17, 2010 Author Report Share Posted August 17, 2010 I recently picked up a pair of them the thunder 7000's they were relatively cheap. they are the 4 ohm version. im running 1 in the tline right now pushing only 150 watts rms and its impressive for 1 12. i havent tryed them in any other type of box yet though. im looking at putting in the second speaker just lookin for the lazy mans way out to not have to build another box Quote Link to comment Share on other sites More sharing options...

Yes, more drivers means more cone area, means more port area(=more square inches). The guy in the video isn't the smartest one, i have told him before that it isn't a tline.

Memphisman Posted August 17, 2010 Author Report Share Posted August 17, 2010 i was pretty sure that i would need the more port area, i just had to ask to be sure. thanks for the help. bout to build another tline for both speakers Quote Link to comment Share on other sites More sharing options...
NcHalfrican Posted August 18, 2010 Report Share Posted August 18, 2010 That isn't a t-line, its a l ported box tuned to 28 hz. If you watch the rest of the video you would see he is selling his t-line for 2 8's not the box for the 4 8's Quote Link to comment Share on other sites More sharing options...
CheezyMane13 Posted August 18, 2010 Report Share Posted August 18, 2010 Neither one looks like a tline, more ported then anything.....
