Hellooo Down There,

Are you wanting to do a hobbyist build or buy stuff?

Like Wayne said, if you can get to a meet that would be great.

Prob'ly the best kit that I've seen is the BK16 from Madisound,
though Wayne may have some other suggestions.

Up in the General Forum there's a few remarks about a book
called Speakerbuilding 201 just released from Old Colony and
the audioXpress mag.

I have a thing for Voigt Pipes and would like to do that
build but for now, there's a smaller design called the MLTL
(Mass Loaded Transmission Line) that I built from shelving
sold at the (put your Home Depot equivalent here.) It's the
best build I've heard, but, well I've mostly only heard my
own. MLTL is a ported design found at the Single Driver Website
where one of the regulars provided the specs for a build with
the Fostex FE127e. I'm still experimenting with the tuning
from what was given by GM, the author. The MLTL has also
been used with the Jordan JX92s which is thought of highly
in full range speaker circles.
