I have improved my impedance measurement jig accuracy and tested my 20 year old T-Line 3 speakers.
There has been argument about whether the later John Wright era TDLs were transmission lines.
The T-Line 3 was a typical 1m high MTM floorstander, like a deeper version of the RTL3.
This graph certainly does not look like a typical reflex. There is a second peak at about 22 HZ, but almost damped out of existence. The phase behaviour is very easy too, 30 degrees maximum.
