Mission 753 speaker modding

[justblair]

Right I measured the DCR of one of the coils in the bass circuit as Peter described.

I'm getting 1.0ohm-0.4 ohm=0.6ohm

My calculations (and online inductor calculations as well) are telling me I should be getting somewhere in this region if not slightly less (0.5ohm approx) though I guess my own coli winding skills will effect this.

On this basis am I right in saying that the air core should have no ill effect on the flabbiness of the bass?
