Let's assume I won't be fooling with the ABC and go on to the next paragraph //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
No, a TL isn't just a gigantic resonating port as far as I know because the resonance only occurs in a ported box because there is a pressure deficit in the chamber after the air is forced out of the port. Only when you add a loading chamber to the beginning to the line (usually about 1/6 of the total line's volume) do you get any resonance effect. Otherwise, it's purely a phase inverter which is what it's supposed to do. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
Sure you can slow down the air flow mechanically with fills, bends, membranes and whatever else you want, but that still doesn't mean it will operate as expected. There are two kinds (as I'm sure you know) of TLs: ones that have output at the port and ones that don't. The ones that don't are merely supposed to be the ideal sealed enclosure as they exhibit no resonance whatsoever at frequencies that the sub will affected by: the rear wave of the speaker is completely damped by the enclosure and the cone is therefore completely controlled by the air in the line. The ones with output at the port are usually what we're looking for, but perhaps I should be looking for the former type. The line will still be ~ the same length, however, and tuning to a speaker's 1/4 Fs when it's
I use my Civic as a daily car and simply want a nice, clean and loud system: not loud speakers with loud bass. I'm using CDT HD-62Z with UpStage and I want it to be seamless like my home audio setups are and although I know that's incredibly difficult due to a car's envirionment, it cannot be impossible. I think it's just that most people have a different idea as to what SQ is than I do. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
