Nope, that was so the Amp's internal resistance becomes irelevant. Remember, in those days the Amp's usually had no negative feedback and often in Studios an AL1 was the output pentode....

Apart from that the entire various interrelations between the classic fundamental parameters and enclosure design where known and understood in the late 40's or earlier, all T&S did was to replace the complex and many fundamental parameters with a few "compound" numbers. In the process they also effectively removed the ability to predict the large signal behaviour of the speakers, sadly.
