You may want to join that forum if still open and pm some of the heavy users who might be around but just not active. I see some older postings at Audio Asylum about Orions, so same thing there.
In the unlikely event of finding one of the older crossovers, looks like you'll be going digital. I don't see that as a negative, but I'm sure it's blasphemy for the true followers. HAL distributes a darn good 4 way crossover. Great potential for a fun and good sounding project.
