Guys, thanks for your help.
I will try to fill-in as much as I can now before testing in cabinets.

1. My source is a variety of music with good bass content.
2. Crossover is a BagEnd infra processor. It is a crossover and EQ in one box. The crossover is around 100 Hz and the EQ is designed to compensate for a sealed box roll off. This is how all bagEnd infra processors work.

3. Both the 12 inch woofer and the 21 inch woofer have been modeled in winISD software and are appropriate for a sealed box with the bag and processor.

4. The variable here is the box size and with the correct box size the rolloff is designed to be about 65 Hz. of course the 21 inch woofer will have a larger box but the target Q is .7 and a rolloff around 65 Hz.

5. The amplifiers a hefty MC2 T1500.

6. I have a feeling that with 100 Hz crossover, the 21 inch woofers do not sound good.
