This is an update on a combination of drivers suggested by rabbitz in the loudspeaker forum. x.onassis started a thread that kicked this whole idea off, and here he has given a nod to what might be considered a good jumping in point for anyone interested in a good solid two-way base for a beginners project, or something to tweak and improve upon. I still don't know how this wiki loudspeaker library is going to develop, but a little sensible practice should probably be observed. If you make alterations to this proposal, either discuss them in the forum before altering this page, or identify your suggestions here in a link to another page. You need only name the link to your idea/change/proposal and enclose it in pairs of brackets and you have instantly created another page.
This is the fun part of the wiki.

rabbitz has added This includes a drawing of the box and crossover plus alternative series crossovers
Part of the impetus of this design is based on the work that generated the TLb, a bipole using the same drivers, and from which the simple XO was lifted.
