Interesting graphs, wondering about how different wiring patterns might work, such as vertical vs horizontal pairs run as two separate channels. Then, if one were running two Devs (8 drivers) what happens with 2 lower & 2 upper drivers wired in parallel, then run in series with the second Dev. That would give all the drivers seeing the same relative position in the horn the same circuit. Wiring would be a little bit of fun, but honestly it wouldn't be that big of a deal, especially if they were located on the same wall.
Hmmm ... might need to get playing on a tuned PR box!
A funny observation from the pics: 2 pairs of drivers ordered at the same time ( I think) and yet 2 different "models"!
Lol, missed your post earlier. I see you had the same thought I did on splitting it into two channels.
As for wiring multiple cabs, run all drivers parallel for 1ohm. Then series two cabs, 2 ohm load. One channel of a nx3000d will run that nicely.
That leaves an open channel though, better add two more.
Four of these would be very serious output, might just give 8 VBSS a run for the $.
EDIT: As for the two different “models” of drivers, the CS1214’s were ordered from amazon, while the gx1200’s were sent by @gpmbc.
