Which version did you get? I have the alnico version and it has a nice thick low midrange and plenty of bottom end in the two guitars I've put it in (both Schecter super strats, one mahogany with maple bolt neck and rosewood, FR, the other all mahogany set neck with ebony, TOM).
I have never used the ceramic one. What guitar did you put it in?
You might have a wiring issue. Are you familiar with BKP wiring?
On my Schecter C-1 Blackjack ATX, which has pickup rings, the pickups are set level with the pickup rings. The bridge isn't set especially high, but there is sufficient clearance from the strings that if it was lacking bass I would have had to jack it up
In terms of resistance readings they are close but the neck should be slightly less. Mine was tested at 8.0 neck and 8.6 bridge, which is in line with advertised spec.
I would also point out that the neck is generally considerably bassier, just because of where it is located. The bridge position naturally has less bass and is weaker just due to its location, so it is generally wound hotter with bigger/more magnets. Both Black Hawk bridge models have three magnets, one has three C8 magnets, the other has three A5 magnets. The neck is generally not used for high-gain rhythm, rather just clean and lead tones.
