I am working on building a Seven Pi clone. (Wayne, you have finally made it - people are building "clones" of your speakers :)It is going to use the new midrange and a 2370-style horn, so it is likely to be quite tall; perhaps as much as five feet tall.
I am planning on building the woofer base separately from the rest; perhaps even separate the mid-range and tweeter, too. (For portability; mainly for bringing it up from the basement!)
Should I put the tweeter underneath the mid-range? It seems like that would be closer to ear level of a seated listener.
