Anybody know how to contact the OG? I've acquired all components but can't find the actual plans. After completion (and presumable awe) I'd like to drop some love on the original designer, but the "Greenboy" website-links all seem dead. Also, "Speaker Hardware", the suggested and endorsed crossover-builder, has contact links that always spit-back as "undeliverable". Fn annoying because after purchasing their full complement of xovers for a pair of 15/6/1's & Sub 15 (=$$$) they won't answer a few basic questions. [Anybody?: 1. - Why aren't the two tweeter xovers (for the 15/6/1's) built with identical components, and could that be a liability for matched L/R cabinet sonics? 2. - In Sub15, is there a problem inserting a simple "Sub/Direct" bipole switch after the jack, "Y" ing to crossover & direct to speaker?] Any leads greatly appreciated.
