Re: FREE MONITOR PLAN: 12" Coaxial "Smithers Wedge" by Michael SmithersI'm not aware of the crossover plans for the BMS driver being published, they were a custom job by Curtis List, and quite a complex design at that. I believe he was selling them for about $150 each, though this was several years ago. Some alternative drivers do have stock crossovers that can be used, which is a much simpler arrangement for most. I believe Michael Smithers has since upgraded his into powered wedges without the need for a passive crossover.
