The one Ilkka measured was in a 100L box, yours was in free air.
Inductance, inschmuctance. The Tumult was the best sub driver of its day, hands down, and the MKII was flat to >300 Hz, for the inductance-phobes. With 30+ mm of one-way throw it got the job done as well as or better than any of the 100+ drivers I've used.
It rolled off around -8dB from 50-100 Hz, according to Ilkka's and my own measurements. With an 80 Hz 4th order LPF (the standard HT X-over), this was easily managed to a flat response through the crossover. You just have to know what you're doing.
