Linkwitz fransform

hey,
I got a few questions concerning subs.
1. Can anyone tell me more or less what a Linkwitz transform does, and how it affects sound/bass response?
2.what is corner frequency?
3. What is better, a high or low Q?
Thanx.

A good start is at this link explaining the EQ required by many Subwoofer designs:

A number of your questions regarding "Q" etc. are also in this article. :)

hey thanks alot that does help me!
