"the idea of a TL is to get rid of all the back energy"
Not at all. The idea of the TL is to make use of the 1/4 wavelength resonance to enhance bass output. The easy way to do so is via a simple pipe enclosure. The problem with a plain pipe is that a series of resonant response peaks are created. The trick of a good TL is to suppress the all the resonant peaks except the 1/4 wavelength. Methods of so doing include, but are not limited to, driver placement, stuffing and tapering of the pipe.
Some of the descriptions in this thread of closed 'TLs' in fact refer the Acoustic Labyrinth concept, which was in its original form intended to totally absorb the backwave, though I've seen the name applied to vented boxes as well.
