I haven't benched it but I do know in that in the right enclosure, the Jordan will go surprisingly low and is extremely coherent regardless, so much so that it makes the Fostex 108 and 126 sound weak and insipid. If the EnABL thing is legit, perhaps that might help close the performance gap between the Fostex and the Jordan, but as it stands, the Fostex drivers I have owned and heard, as good as they are, are not in the same league as the Jordan.
