If you're happy about the 2226J's because two in parallel will give 8 ohms in the lowest bass frequencies, that much is true. But it will also mean that the impedance from midrange up will be 16 ohms, changing your crossover values and making you need coils that are twice as big. That's not a huge problem, but it isn't trivial either. I think I'd prefer 2226H's.

As for the port you mentioned in your other post, a slot will probably work, provided the area and length are kept the same. I'd measure impedance to be sure though, and find out where box resonance is. I would also be concerned about standing waves, since the port will now be somewhat wide and thin. It might cause a peak somehwere in the lower midrange.
