May I have a link for it please?VCAD has an enclosure simulator based on T/S parameters. quite straight forward if you ask me.

I was searching as "VCAD" and failing. I found it now. Many thanks.
I've installed VituixCAD2 but unless I am wrong it doesn't come with a library of drivers. You can create one but the argument I was making is it is not easy to search all drivers on the market one by one.
Yep - VituixCAD is exactly what you want, specifically the "enclosure" section in tools. VCAD is leading the way in complete speaker design software imo, REW for measurements.I was searching as "VCAD" and failing. I found it now. Many thanks.

Also, it is an unnecessarily complex application for the simple job I have tried to explain, which basically finding the suitability of a drive unit to a given enclosure.

Could you please show how the tuning will be if the design was sealed? I typically don't like anything in the rear of my speakers and it would be one thing less to do when I build the speaker.
I'm hoping the response would be flat to 80Hz (or at least the LF roll-off would be @80Hz) .
I’m failing to explain what I am looking. I am looking for a driver database, where simple parameters including TS values that is attached to a simple calculator. It’s to be a tool to find suitable drivers for an enclosure.I think if such a program exists you would be unemployed .
Aside from having to enter the T/S manually if it's not included in the list already, I think it does exactly what you want it to do, no?
I'm not sure whether a curated Database exists out there similar to other industries, perhaps other members may chime in.I am looking for a driver database
Enter your enclosure volume and decide closed or ported. The calculator will plot the FR and show the f3 for the selected driver. This will help one to eliminate the drivers that are not suitable in your enclosure size.
I doesn‘t need to be curated just the data of the basic parameters of each driver. As there are various databases linked to posts here I was hoping one to exist.I'm not sure whether a curated Database exists out there similar to other industries, perhaps other members may chime in.

I'll check the iOS app. Meanwhile, I find the online switch and there are indeed a lot of drivers. Thank you for your help.For a quick check, I use an IOS app called Speaker Box Lite.
VCAD has a fair number of drivers, but to see them fully, you need to check the online data box in the Enclosure calculator.
WinISD has generally been the standard tool used for subwoofer modelling, and there are various collections of drivers out there. I'm not sure about more recent drivers like the Purifi though. WinISD has a decent data entry process though- it applies consistency checks as-you-go, and it's a relatively painless process to enter a new driver from the manufacturer data sheets.I doesn‘t need to be curated just the data of the basic parameters of each driver.

This is excellent as a database. All it needs is the following.
The cabinet volume is, of course, much too large. But better that way than the other way around. If necessary you can reduce the volume by fixing a styrofoam cuboid, a brick, Head of neighbor's dog,... inside the enclosure.
With 15L internal volume the frequency response below is to be expected. The dashed curves represent possible filter targets at 80Hz - BU12dB@80Hz and LR24dB@80Hz.

However, the whole thing only makes sense if you plan to use an active speaker. As a passive speaker it will not work with this driver.
As I said, you can still adjust the volume if necessary, I have simulated it here with 15L further.
Already one simple filter (BU18dB@75Hz) and you can almost achieve an ideal LR24dB filter slope at 80Hz. The remaining correction with PEQ and, or cabinet volume reduction.

At a crossover frequency of 80Hz, the Xmax of the woofer no longer plays a role. Before this limit is reached, the woofer gets thermal problems.

Trouble with the neighbor's dog?
