    t line enclosure

    I want to experiment with a t line, I have really no definite answer, perhaps there is none, I know it requires quite a bit of space for a properly designed t line, what exactly are the advantages of a t line?

    Re: t line enclosure

    Another advantage of wave transmission lines is that they're super easy to calculate. Of course, that's offset by the difficulty in designing the box to fit in your vehicle but on balance, I think it's well worth the difficulty.

    They play well throughout the sub bass region and normally extend to about one octave below driver Fs before going -3dB... which is super low compared with the response of a conventional ported enclosure tuned in the low 30s.

    Drivers with a Qts above 7 and a Qes below 4 are best suited for them but any sub will perform its best in a t-line.

    Here are some resources on them:
    Transmission Line Speakers
    Quarter Wavelength Loudspeaker Design

    Here are a few I've built:

    I've always heard that T-lines usually will give you far and away the highest output, it's just a pain in the *** to build them lol

    Depends on what you mean by build. The actual build process is no more difficult than a properly constructed ported box but, designing them to fit in a vehicle can be a challenge, given that a line for a small sub with an Fs of 30Hz will be about 9' long.

    And calculating one can be done with a simple, garden variety calculator... no software needed.

    Re: t line enclosure

    Divide 1120 by the fs of your choice of sub and divide that by 4
    (1128/fs)/4 and that will be the length of your t line

    I'm getting 8.09 feet, would it make a difference with 4 subs over 1?

    No. The length stays the same. Your line volume will be x4. The length of the line has to do with the fs of the sub. The diameter of the line increases with more cone area
