Nope. They are both still TL enclosures, 1 is tapered and the other is not. The tapered TL looks like it is less efficient due to less volume. What are the total volumes of each enclosure?
if i add the 'perfect' parallel resonator to an exisitng TL then the '8th order impedance stuff isnt anywhere in the 'bandwidth'? add an L45 as a 3600cm2 x 150 cm series resonator to this and you get a parafle/ROAR combo and its truely a HIGHER order qw design then?
what gets confusing is the random size/length ‘paraflex’ design use to join the other resonator and the crazy ringing and phase discontinuit’s in their results . Nothing makes ’seMae’, but apparently it all works out when the ‘DJ’ can remove the issues with dsp?
BW seems to differ.
Technically, a mass loaded sealed or BR enclosure would have a line if modeled as an offset driver.
What's your definition of line?
TL's are supposed to be at least 72in or 6ft long.
282qwft / 6ft = 47hz...bass bin, not SUBwoofer.
If 4 string bass = 41hz, then SUBbass = <41hz.

All I know is 1 peak = 2 orders.
If you got 4 distinctive peaks in the electrical impedance graph, then you have an 8th order enclosure.
The grey line has 4 distinct peaks.
It's interesting that the green line has a 5th peak that is more distinct than the the 4th peak. The green line could be a 10th order enclosure.
Is a TL with multiple resonances the same thing as a bunch of series tuned helmholtz resonaturs seperated by odd number resonances? A bunch of capacitors(chamber) and inductors (port)?
what about a 60 cm (24”/144hz ) qw pipe for a kick bin or whatever? A TL is any length you want it to be
A TL is single chamber enclosure where the enclosure is the port, unless you have a compression (coupling) chamber.
It doesn’t matter what it looks like. It matters what the air is doing inside . Kinda looks like the second resonance in a ‘TL’ ? Lots of things are ‘TL’ (whatever that actually is? I dunno, that’s why I don’t care about these games with names that never look at the physics instead?
isnt that just a ‘dalene’ style ‘ TL’?

There is nothing really special about a TL enclosure. There is a TL thread on this forum where someone built a coupling chamber TL, measured it, then took out the "line," measured it, and the regular BR enclosure had better performance with the exact same enclosure volume.
The only way to make a TL special is to show off the "line" with plexiglass or it looks like a regular BR tower speaker.

I ‘almost’ agree(??) …. But , (and kick my butt
if I’m wrong here) what if I want a really big box with a really low fundametal and ‘knee’ shape whilst retaining the most cone control and least port velocity?
I have to use ‘TL’ because the generic bass reflex port and chamber runs out of cone control and into port velocity issues.
basicslly Youre forced to move from bass reflex to tapered qw tube(or I need to learn how to make appropriate ‘big vented reflex’ boxes or sonething?

It’s just a sealed box with an unecessary set of resonances at 96,192,288,384…. Hz Do to the 6 foot standing waves?
