If VC's lasted forever, then speaker makers wouldn't make any money!
I always design my BP4's with the driver's basket in the vented chamber of the enclosure for VC cooling.
HR actually has an option where you can close the front chamber with S1-S2 and L12.

The electrical impedance and maybe some other stuff looks wrong.not possible. BP also does not work that way.
And as with any conventional bassreflex box, it only takes for the DJ to pick the note to push into visitors intestines and ears to be the same as the port tuning frequency, and you are done. Either heavily compressed or limited or burnt. My approach with zero impedance minimum (yours is not valid interpretation of the box) cannot be put in such situation.

It's not a BP enclosure. Your original request was small BR enclosure.
It might be the HR version. I only have 50.70. I cannot update to the current version due to IT security on my work laptop. However, David MacBean said that's the best way to model a BR enclosure on his program. I usually just use the Vrc, Lrc, Ap, and Lpt fields to model a BR enclosure.

I can't on my work laptop. I rarely boot up my home laptop. 99% of my posts are from my work laptop or phone.
Well the new stuff is always with a markup for 6-12 months. Still, no availability info.
So, still not much of anything. I was about to pull the trigger on LN19S400, but it seems the TS parameters don't add up much. Impedance curve on RCF site is way off, as well as Q parameters. Now what.
Preferably to start with two, and if good, continue with another pair. But this knowledge gets expensive, especially when it is a failure. I will try to math out the issue. Hopefully I find what data is wrong, to be sure to buy/pass on it.
@Tumikku: yes, but given the faulty data presented, we have not much idea if it is a good choice or not.
It seems half way to me that the LN16S400 is the 19" impedance curve and vice versa.
Also same motor but different cone size should scale with Qes accordingly. The larger driver should have higher number. I counted 0.24 and 0.3 respectively. At that point LN19S400 cannot do what I'm asking a speaker to do for me. The deal ia off...

I am looking for measuring gear , I will source a couple of toys for me, 1st I need measuring mic and interface , I will use REW and the other software that I can't recall right now , it is also free , do phase and freq graphs live like smart but it is within my price range (freee) 😆
And also I want to have the box to measure the T/S parameters on drivers , is the Dayton on parts express ok?
I want to contribute with real T/S data on the drivers I will use to compare to the manufacturer specs , I know that sometimes they are way off and also out of the box drivers vs. 24 hrs break in process. And compare what shifts.

Yes, Dayton measurement gear is okay. Carefully with the knowledge, it gets expensive. Who would have thought we will learn with our wallets. 🙂 .
Do they have same motor, the Le is different by data on RCF website? I don't argue what you say, I'm interested what you see in the TS specifications that made you suspect error/problem, and how and what you calculated/confirmed?
edit. do you mean by same motor that the Bl are same for bpth of these drivers? So is it just that Qes would differ by
and the calculated value doesn't match what is on the datasheet?
