So, thanks to my income tax return, I can finally afford to get a decent set of subs. So far, it's a toss up between the q and the BL.

The question that I have though... What is the BP Power option on the Q?

This new option adds a machined aluminum compression plug to the pole which helps channel all of the air under the dustcap around the coil for better cooling. To aid with this increased airflow we also add 6 axial cooling channels in the top plate. Along with increased thermal capacity comes the addition of an extra spider and a changed spider pack for a little extra mechanical ability.

All of these new features increase power handling from 200-500 Watts depending on the application.

Its just another way of tuning and tailoring your subs to your exact needs.

As explained by Scott

thanks. But, will this make a big difference in the T/S parameters or enclosure design?

Nope.
