What Is Fb?

I just got a Kicker L7 "12 and on one of the recommended vented boxes it says: Fb=37Hz. I'm rookie and was hoping someone could help me out.

Its the tuning frequency of the box they recommended.
If you follow the plans, thats what the port
will be tuned to, meaning that will be the center
frequency the sub will play at.

No guy, if you build the box according to the spec, the box port will give you 37Hz.

a ported box has a tuned frequency. this is where the box is most efficient and puts out the most bass with the least power essentially.

the tuned frequency is based on enclosure volume, and port cross-sectional area.

If you want a pre-made box for an L7 try www.bigdogcaraudio.com
they carry several I believe.
all built to spec for those subs
