Sanitarium Posted August 20, 2011 Report Share Posted August 20, 2011 Higher tuning always dimenishes lower bass. Quote Link to comment Share on other sites More sharing options...
brennan88 Posted August 20, 2011 Report Share Posted August 20, 2011 I don't believe so. I've heard one t line, a rockford fosgate t2 12 off about 1000 rms and it was tuned to 44hz to match his bass boost. Not sure exact hz but to the ear it dropped pretty low and clean. I remembered him saying the port area was really important, but not too sure though.

nCOMP1337 Posted August 20, 2011 Report Share Posted August 20, 2011 (edited) well thats just turrible tuning to the bass boost, LOL but to each his own forevrbumpn has stated that tlines can normally play well up to an octave below and above tuning, however sani is also right saying higher tuning can hurt the ability to play lows a lot of it is how close to the t/s of the sub you build the tline, as well as whether its a constant port area tline or a taper tline or a bandpass tline, if you need to lower port area, see if you can taper it from 150 to 140 rather than just going with a lower port area, tapering may help with space issues and should still offer good response as always with tline questions you should also check the sticky in the enclosure thread and see if others have had a similar issue or hope to get more responses hear by people that may have more experience with tlines edit: also dont try to get more out of a tline than it can give, tlines arent normally built with low end monster bass in mind, their normally for tight accurate bass response within a good range of tuning and also for getting loud on lower power Edited August 20, 2011 by kynto Quote Link to comment Share on other sites More sharing options...
brent379 Posted August 20, 2011 Author Report Share Posted August 20, 2011 Anyone ever seen/heard of a u shaped tline with the subs in the middle?? Quote Link to comment Share on other sites More sharing options...
Quiet Posted August 20, 2011 Report Share Posted August 20, 2011 Wait got confused i meant higher...so from 35hz to like,40hz. Would i loose and low bass?? Depends on the Qms and Qts of the sub. Some will dip down pretty low below tuning but the tuning itself controls the movement of the sub at the tuning frequency. Below tuning, the sub tends to unload. Port area, enclosure volume, cabin gain and Qts/Qms can all affect how low you can go below tuning. In the most general sense, Tuning Higher = more SPL above tuning, less low end Tuning Lower = Less SPL above tuning, subs reach deeper notes. Anyone ever seen/heard of a u shaped tline with the subs in the middle?? Maybe not so much in the middle, but a little space off the closed end of the line can help with loading...

brent379 Posted August 21, 2011 Author Report Share Posted August 21, 2011 I got it figured out.... Its gonna be my first tline build so ima just play with it a lil bit... The design i got will tune it to basically 45hz..but my port area will match perfect so i guess we will see wat happens!!! Quote Link to comment Share on other sites More sharing options...
homiewes Posted August 21, 2011 Report Share Posted August 21, 2011 if you like low notes, then just tune it low, i dont think 45hz will give you any kind of brutal low bass LOL Quote My youtube channel, please subscribehttp://www.youtube.com/ballinblaza Link to comment Share on other sites More sharing options...
