It causes the sub to react as if it has more air volume than there actually is.
Most say a 10% increase, some argue higher.
Dont forget you need to deduct the space your woofer consumes from your total box volume as well.
Thanks, bro. The amp has made all the difference; waay better sound quality and way louder. I'll probably go with the upfire config and polyfill just to squeeze out a little extra SQ.

I have 4 channels to work with from the amp. I've read that active crossovers are better than passive. Would I get noticeably better SQ by running my tweeters and woofers all to separate channels and using the amp as a crossover (hi-pass filter) instead of the passive crossovers? How do I find how much power to send to the tweets vs. woofers and what crossover frequency to use for each?
