bass reflex vs double chamber reflex (ABC/DCR and DCAAV)

I would like to know if anyone has compared the systems in the figure (and possibly also the load n ° 15 type B6 by Thieele) can tell me the disadvantages and advantages of each with evidence for the aspect of impulse response or transients (also with respect to a closed case), beyond the frequency response in cutoff frequency (F3).

With every added order due to added reflex chambers impulse response gets worse. But efficiency can be gained. This is what I know from 4th order 6th order and 8th order alignments.

There are classical single reflex alignments which were studied for being good compromises concerning impulse response.

Far as I remember few benefits.
Which become more noted when modeling.

Been awhile forget...

Most probably want mystical magical more bass.

But remember at least having more control of upper and lower response
and if all else fails could get the same tuning and " alignment"
as a Butterworth. But made the first chamber smaller so could squeeze
a little more power handling from the driver. When I cared about massive power levels.
but otherwise made total size bigger.

should try again been awhile.
was originally interested in mainly tall towers.
Sometimes bigger or taller than needed.
so why not fill it with another chamber. get rid
of the lower Uhh Ohh area with a tall box
