Post Subject: Returning the wavePosted by Jorge on: 9/30/2013

Well the thing is that the returning wave from the back side of the driver, does return in phase, but "later" than the front wave, logically. This should add some distortion that I have not noticed, but of course and worried for as much as I am worried for the unused RCA conectors in my preamplifier, or the brand of cable lifts I will be using...
Making a TH for a higher frequency is actually much easier since the labrynth would be much shorter. I have several designs for this but never made them due to this concerns.
So for the frequencies below our UBH it works nicely, I am sure it would work even better as ULF, but it would be prohibitively big, well much bigger than a selaed enclosure Sub which can be pretty small with a long throw subwoofer that will do the job.
Now to use it instead of my UBH: I have seriuos reservations, but never tried it....
TH do have a lot of cabinet walls and if not treated properly (a lot) any small cabinet reverberation colors the sound terribly.
