Hey Jack,
I asked my engineer your question regarding the reason behind the seemingly high-ish Le and this is his response.

Your driver has a high Le because it has a 4 layer voice coil; I chose this for its added mass and to purposely roll off the high end. I am not convinced Le is a huge issue when you are crossing these things over very low (say below 90 Hz). I cross my two IB 15's over at 40 Hz with a 24 dB per octave slope and sit almost directly under them and I can only localize them when something in the ceiling squeaks or squawks.

I also asked about the Dayton driver and is seems that they did not get involved with the design of these drivers.... They refrained from comment on the Dayton drivers...
My speculation is that if they intended them to be used for IB, they would promote this in their sales and marketing of this driver. I have a good working relationship with Part express and I can only say nice things about their products and customer service. They have always done well by us.
