Anything ‘wrong’ with this?
Maybe there’s a ‘better’ use of chamber or port size/shape to arrive at a similar Fb?
Seems like I can really drag a high QTS driver down low regardless of its Fs in some of these big vented boxes? ( Fs 46 hz , Qts 0.75)

High Qts woofers with a resulting very strong port output peak are sensitive to parameter changes and tuning inaccuracies or shifts.
Not sure if it is a real problem, though.
(Much) reduced power handling/GD, but otherwise.............Indeed! FYI/FWIW, the pioneers made so called reactance annulled horns, mass loaded speakers = Flc = Fs*Qts'/2 = 17.25 Hz!
(Qts'): (Qts) + any added series resistance (Rs):

What does a ‘weak motored’ (high QTs) driver do outside of resonace? Tend to flop around and potentially sound funny?
I cannot understand hornresp parameters of S3-S4 (100cm x 0.01cm) with respect to drawing
I may be wrong but I'll assume far enough above enclosure and driver resonance the weak motor only relates to efficiency/sensitivity.
The OD section has the third line ‘minimized as 0.01cm’ so the port can be described in ‘Ap/Lpt’ and ‘Qlosses’ is then adjustable
(Had to double click on ‘Clo’ up in the right hand corner as well )
It’s kinda tricky/confusing for me too
I think whatever is happening at and below the second resonace is extremely audible to anyone used to (or requiring) non resonace sound in that area and where these designs really start to annoy people ? It’s the details of bass instruments and male vocals that become muddy and weird ??
Try listening to Metallica in that ? Or in a ROAR, where it’s even ‘worse’ with an even longer/lower frequency resonace bump?
