What frequency/slope are you crossing at? Per Rhljazz, if you want that kick drum fundamental handled by the sub you'll need to cross high enough to route the signal accordingly. Depending on the slope you're using, that may well be north of 100hz. I also agree with Bob's observation re: the room. My own experience is that dealing with all these issues - time alignment, room nodes, crossover point, slope and phase, etc - makes it very difficult to optimize subwoofer set-up by ear.
I'm a digital room correction guy and - even tho Audyssey my get you drummed out of the audiophile club - believe that it dramatically increases the chance of excellent subwoofer integration.
