Opinions on this Sub

[callas01]

Big Daddy, You seem to have a vast sum of insite to these Subs, let me ask a few questions

1. Will the 23-200 hz RW-12 vs the 20-200 hz HD-Sub12 is the lower 3 hz gonna be a big difference in what I hear and experience?

2. Are these Subs accurate? Are the muddy? I mostly watch BD's with music being about 10% of the time, would either one be better?

3. In a room the where the size measures approx 13W x 16L with the width to my front and back and the length is right to left, how much wattage would I really need from a Sub?

Thanks.

EDIT: didn't see your post.
