Transmission Line vs Reflex Ported vs Isobaric
Just wanted to know if anyone knows the advantages or disadvantages of each...in layman's lingo.
This would be in terms of quantity, quality and tunefulness of the bass produced.
I have heard that TL is more difficult to get right and so possibly more expensive to produce...as well as being drier sounding and possibly less weighty. I have also read this, which I don't know if it's true, and I paraphrase:
"Real world TL speakers like PMC are really quarter-wave TLs, ie. the line length is 1/4 the wavelength of the resonance frequency the bass driver is tuned to.
This means it's nothing but a Bass Reflex variant, that offers no real advantage over a classic Reflex alignment."
So any comments, preferences or insights would be much appreciated.
