You just answered my question:

So if you can't flip the N23 (due to issues with the inverse N23 build), how about,
to get close to my 380cm length with 4 arrays:
N23 N23 N19[+3] N23 = 377cm
N19 with a constant of +3 yields: 940LF - 4300HF
(effective: 470Hz - 8600HF)
Follows the Barker code.
Any thoughts on this?
PS From above, in the text, "the best design is one with a small number of periods..." just taking this partial statement, "small number" isn't specific. Then the sentence continues, "say, five" perhaps implying that 5 periods is recommended -- but in all situations, large and small rooms, opposite walls close or distant, mic position, etc. Unexplained?
Thanks too for your comments, Terry.
