I don't have that file. A quick search found that 3 cu feet was a good box volume for these. I found that info in the picture of the spec sheet posted here. https://mullardantiques.co.uk/produ...edale-super-10-rs-dd-loudspeaker-driver-units If you have the drivers in hand it is not difficult to measure them yourself. Download the Arta software for PC from this site. https://www.artalabs.hr/download.htm Read the manual regarding the single resistor measurement setup for using a PC sound headphone output, line level input for the Limp program. It will let you measure the TS parameters for winISD in a few minutes. The fun of diy Audio is the DIY part.
I keep forgetting to post that it would be nice to upload any new files here for posterity and it be added as a 'sticky' somewhere.
korg "The software at £74.26 is expensive for a one off project though"
The software can be run in demo mode forever for free. You can make measurements and perform the TS parameter calculations with it for free. In demo mode only the file save function is disabled. You don't need to save any files to perform all the measurements and analysis. If you decide to build more than one speaker I can't think of a better value for the money than the Arta software suite. The manual is practically a textbook on how to make measurements. With the Arta and Limp you can measure and export .frd (gain and phase) and .zma (impedance files for use in free crossover design programs like Xsim. I believe Room EQ Wizard can also measure impedance, but I have not it to do that myself. There are YouTube videos that can help you use either program.

10" and 2 cubic feet is quoted as the volume used.
Far as reflex tuning. Whatever Fs is
seen sales add saying Fs between 2 units measured at 38 and 40 Hz.
