Yup, got it!
Yes, the 40mm well width is anecdotal for sure, though expertly so. I suppose it will take more voices and some digging to learn more. It's too bad that a fair degree of LF bandwidth is sacrificed, between the N23 and N23+2...
Well I am on to building the N19+3 as my modulation period. Reading over the design Hz/MWD discussion, I surmise that, if plate Hz isn't an issue (as with larger primes), then, if it's not otherwise problematic in the space, matching the design frequency between +1/-1 panels is a good thing, and as the difference for me is only a matter of 8mm shorter, it's easy to accomplish (I can use my same frame as with N23, but my max wells will be 127mm not 135, which means they will have 5.5mm spacers under them (plus 2.5mm faces). When the modulation panel is a bit shorter the design execution is easy.

Trevor seems to say that because your order is high enough for this not to be an issue, you can take your pick....
The use of 40mm wells is anecdotal at this stage. Will need to think more about it before allowing qrdude to move that far from the Shroeder ratio.
Taking N23+2 (at 135mm MWD), when I switch to Inverse mode, if I go to N23i+4, I get a MWD of 132mm. What do you think of this approach?
Once you rotate the phase wheel after shifting to the inverse, you generate a new normal/inverse pair. Switching back to the normal panel, you'll see its not the one you started with.
The N23+2 / I23-2 pairing was the closest match for build depths. |
